Provision Circuits/VCs

Provision Circuits/VCs in Cisco EPN Manager

The process of creating and provisioning a circuit/VC is similar for all the supported technologies and involves:

  • Specifying the endpoints of the circuit/VC.

  • Defining the configuration parameters of the circuit/VC.

For a detailed overview of the provisioning support in Cisco EPN Manager, see Provision Circuits/VCs.

To create and provision a new circuit/VC:

Procedure

Step 1

From the left sidebar, choose Maps > Topology Maps > Network Topology.

Step 2

Click on the Device Groups button, select the required device group(s) and click Load.

Step 3

Close the Device Groups popup window.

Step 4

In the Network Topology window, click the Circuits/VCs tab.

Step 5

Click the '+' icon to open the Provisioning Wizard in a new pane to the right of the map.

Note 

You can also access the Provisioning wizard by choosing Configuration > Network > Service Provisioning

Step 6

From the Technology drop-down list, choose the required technology. For example, if you are creating a circuit for Optical/DWDM network, choose Optical.

Step 7

In the Service Type area, choose the type of circuit/VC you want to create. For example, if you are creating a circuit/VC for Optical/DWDM network, the various circuit types include OCHNC WSON, OCHCC WSON, OCH-Trail WSON, OCH-Trail UNI, ODU UNI, ODU Tunnel and OPU over ODU.

Step 8

If you have defined profiles to set the attributes of the different services, select the required profile from the Select Profile drop-down list. See Create Circuit/VC Profiles.

Step 9

Click Next to go to the Customer Service Details page.

Step 10

(Optional) Select the customer for whom the circuit/VC is being created. If there are no customers in the list, go to Inventory > Other > Customers to create the customer in the system, and then go to the Provisioning Wizard to start provisioning the circuit/VC.

Step 11

Enter the service name and its description.

Step 12

From the Deployment Action drop-down list, choose the action that you want to perform after defining the attributes for the circuit/VC. The options are:

  • Preview—Displays the generated CLIs for each device. You can review the CLIs and decide if you want to edit any attributes or go ahead with the deployment.

  • Deploy—Deploys the configuration to the relevant devices immediately after you click Submit in the last page of the Provisioning Wizard.

    Click one of the following deployment options:

    • Deploy Now—Directly deploys the provisioning order

    • Deploy Later—Saves the created provisioning order.You can deploy the same order at later point of time.To redeploy the provsiioning order click the circuit/VCs link at the bottom of the left pane.

    • Schedule Deployment—Saves the order for furture deployment at the designated time provided by you. Schedules the provisioning order and creates the Job order to be deployed at the scheduled time. If required, you can specify the date and time to provision the order in the Job Scheduler.dialog box.

      If you click this Schedule Deployment radio button, specify the following:

      • Deploy Schedule Time—Specify a schedule time for deployment of provision order.

      • Server Time—Displays the current server time.

    To know more about how to schedule and save a provisioning order, see Save and Schedule a Provisioning Order
Step 13

Click Next to choose the endpoints and define the attributes based on the technology you have selected.

Step 14

Click Submit. Depending on the deployment action you have chosen, the relevant action will be performed. That is, if you have chosen to preview the configuration, the preview page will be displayed where you can view the configurations, and then click Deploy. If you have chosen to deploy, the configurations will be directly deployed to the relevant devices.

Step 15

(Optional) Click the Leave this View button to continue using Cisco EPN Manager and to enable the service deployment to continue in the background.

Note 

If the device is busy, the request from Cisco EPN Manager to deploy the service will wait up to a pre-configured period of time before the request times out. To change this setting, see Set the Service Deployment Timeout Value.

The circuit/VC should be added to the list in the Circuits/VCs pane in the Network Topology window. To check the provisioning state, click the i icon next to the circuit/VC name to see the Circuit/VC 360 view.
For information about how to create and provision circuit/VCs for various technologies, see:

You can view the saved provisioning order in the Planned Circuits/VCs tab from Administration > Dashboards > Job Dashboard > Provisioning.

Click the (I) icon at the Last run stat field and view the configuration and Device details.

Set the Service Deployment Timeout Value

When you deploy a service to devices, if the devices are pre-occupied or busy, the service request created waits for a pre-configured period of time to acquire a ‘device lock’ for deploying the service. By default, the timeout value is set to 60 minutes.

To change the default timeout value:

Procedure

Step 1

From the left sidebar, choose Administration > Settings > System Settings .

Step 2

Expand the Circuits/VCs section and click Deployment Settings.

Step 3

Set the required timeout value in minutes.

Cisco EPN Manager will now wait up to the specified time period to acquire the device lock for deploying the service. If the lock is not acquired within this time, the service deploy operation will fail.

What Happens When a Deployment Fails

When you deploy a circuit/VC, Cisco EPN Manager performs configuration changes in the participating devices based on the type of circuit/VC. Only when the configuration changes are successfully deployed to the devices, the circuit/VC will be considered as successfully provisioned. If the deployment of configuration changes fails in any one of the participating device, Cisco EPN Manager rolls back the configuration changes made so far in all the devices.

Deployment action can result in any one of the following scenarios:

  • Deployment succeeds in all the participating devices; roll back is not initiated—In this scenario, all devices are successfully configured and the circuit provisioning is successful.

  • Deployment fails; roll back is initiated and succeeds—In this scenario, when configuring multiple devices, the configuration fails in one of the device. The failure could be due to various reasons, for example, the device has declined the configuration. Cisco EPN Manager identifies the failure and successfully rolls back all the configuration changes that were made on all the devices. In this scenario, all device configurations are restored to the states, which were there before the deployment was attempted.

    Here is an example with three devices, A, B, and C, which are configured in a sequential order to provision a circuit. The configuration changes are deployed successfully in device A, but the deployment fails in device B. Cisco EPN Manager detects the failure and stops further configuration in devices B and C. It rolls back the configuration in the reverse order of provisioning, that is, it first rolls back the device B, followed by device A. Following are the actions that are performed sequentially in the three devices:

    • Device C—Rollback is not required for device C because there were no changes deployed to the device. This is because the configuration failure was detected in device B before configurations changes were sent to device C.

    • Device B—Cisco EPN Manager checks if there are any configuration changes made on this device before the deployment failed. If there are any changes, the partial configuration on this device is removed and the device is rolled back to the previous configuration.

    • Device A—Cisco EPN Manager performs a complete roll back in device A, where all the configuration changes that were successfully deployed earlier are removed and the device is rolled back to the previous configuration.

  • Deployment fails; roll back is initiated but fails— In this scenario, when the configuration deployment fails on any of the participating device(s), Cisco EPN Manager performs a roll back, but the roll back on one or more devices fail. Now, the device(s) on which the roll back had failed, has the partial configuration.

    For example, the configuration changes are successfully deployed in devices A and B, the deployment fails in device C. Cisco EPN Manager identifies the failure and initiates the roll back in the reverse order of provisioning, that is, it first rolls back the device C, device B, and then device A. Following are the actions that are performed sequentially in the three devices:

    • Device C—Cisco EPN Manager performs a successful roll back in device C.

    • Device B—When attempting a rollback on device B, device connectivity is lost and there could be partial configurations left on the device.

    • Device A—Cisco EPN Manager performs a rollback of Device A, even if the roll back fails in device B.


Note

The roll back may fail due to various other reasons.

In the Provisioning Wizard, after previewing the configurations, click Deploy. When the deployment fails, the rollback configuration and the status for each participating device is displayed. From the Device(s) drop-down list, choose the device for which you want to view the rollback configuration and the status.

The following figure illustrates the rollback configuration and the rollback status for each device.

1

Attempted Configuration— Shows the configurations that were deployed to the device selected in the Device(s) drop-down list.

2

Deployment Status— Shows the deployment status of the selected device. If the deployment succeeds, it shows the status as "Success". If the deployment fails, it provides information about the failure.

3

Roll back Configuration— Shows the configurations for which rollback is automatically attempted.

4

Roll back Status— Shows the roll back status of the selected device. If the roll back succeeds, it shows the status as "Success". If the roll back fails, it provides information about the failure. You can use this information to manually clean up the partial configurations on the device.

You can also click the i icon next to the Provisioning column in the Circuits/VCs and Deleted Circuits/VCs tabs in the extended tables to view the details of configuration, configuration errors, rollback configuration, and rollback configuration errors for each device participating in the circuit/VC. The i icon is available for all provisioning states, except None. For information about how to access the extended tables, see View Detailed Tables of Alarms, Network Interfaces, Circuits/VCs, and Links from a Network Topology Map.

For information about how to troubleshoot deployment and rollback failures, see Troubleshoot Configuration Deployment Failures and Roll Back Failures.

Troubleshoot Configuration Deployment Failures and Roll Back Failures

Following are the tips to troubleshoot the deployment or roll back failures:

  • Deployment fails, but roll back succeeds— If the configuration deployment fails, roll back is automatically initiated and the results are displayed in the results page. Analyze the attempted configuration and error message shown in the results page for each device and identify the root cause of the deployment failure.

    The deployment failure could be due to, but not limited to the following issues:

    • Invalid values entered for the service parameters in the Provisioning Wizard. For example, the Service ID may already exists or there could be semantic errors in the CLI that is generated, and so on.

    • Device issues such as, device is not reachable, device password has changed, and so on.

    In this case, you must locate the circuit (by the name that you had given when creating it) for which deployment has failed, edit the circuit, and re-attempt the provisioning. If the service parameter for which the value to be changed is not editable, delete the circuit and create a new circuit.

    Note

    Before deleting the circuit, ensure that it is not in use.

  • Both, deployment and roll back fails— In this case, do the following:

    1. Ensure that the device is reachable and perform a device re-synch.

    2. If there were any device issues that were reported in the previous deployment, try to fix the issues.

    3. Edit the circuit and update the attributes, if required, and then re-attempt the circuit deployment.

    4. If the deployment fails, Cisco EPN Manager will initiate the roll back.

    5. If the roll back fails again, identify the cause of the roll back failure.

    6. To identify the cause of the failure, you can use the configuration and roll back transaction details, history of the service deployment attempts, and the roll back attempts that are displayed in the Circuit/VC 360 view. See Get Quick Information About a Circuit/VC: Circuit/VC 360 View.

    7. Manually remove the partial configurations that are stored on the device.

You can also contact the Cisco representative to analyze and identify the root cause of configuration deployment failure and roll back failure.

WAN Automation Engine Integration

Cisco WAN Automation Engine Integration with Cisco EPN Manager

The Cisco WAN Automation Engine (WAE) platform is an open, programmable framework that interconnects software modules, communicates with the network, and provides APIs to interface with external applications.

Cisco WAE provides the tools to create and maintain a model of the current network through continuous monitoring and analysis of the network and based on traffic demands that are placed on it. This network model contains all relevant information about a network at a given time, including topology, configuration, and traffic information. You can use this information as a basis for analyzing the impact on the network due to changes in traffic demands, paths, node and link failures, network optimizations, or other changes.


Note

For details, refer to the latest Cisco WAN Automation Engine (WAE) Installation Guide and Cisco WAN Automation Engine (WAE) User Guide.

In Cisco EPN Manager, when you create an unidirectional or a Bi-directional tunnel with an explicit path, the WAN Automation Engine (WAE) integration provides you the explicit path using a REST call from Cisco EPN Manager automatically. Thus, you can avoid manually entering the explicit paths. WAE provides you a list of possible network paths to review and allows you to select an appropriate path.

Configure WAE Parameters

To specify the WAE path details:
Before you begin

Ensure to set the WAE parameters:

  1. Choose Administration > Settings > System Settings

  2. Expand Circuit VCs and then choose WAE Server Settings.

  3. Enter the relevant WAE Details ( version 7.1.1 and above) and field details such as WAE Server IP, WAE Port Address, WAE Server User Name, WAE Server Password, and WAE Network Name.

  4. Click Save to save the WAE server settings or click Reset to Defaults to use the default values.

Procedure
Step 1

Create an Unidirectional or Bidirectional tunnel with necessary parameters. For more information, see Create and Provision an MPLS TE Tunnel.

Step 2

In the Path Constraints Details area, choose the path type either as Working or Protected. See Field References for Path Constraint Details—MPLS TE Tunnel for descriptions of the fields and attributes.

Step 3

Check the New Path check box to enable the Choose Path from WAE server check box.

Step 4

Check the Choose Path from WAE server checkbox. EPNM manager sends a REST request to WAE to obtain WAE networks.

WAE will return a list of possible networks.
Step 5

From the Select WAE Network drop-down list, choose a network.

EPNM manager will send a REST request to WAE with all the required parameters such as Source, Destination, network; Max path returned default value = 2. WAE displays a list of possible paths satisfying the request.
Step 6

From the Select WAE Path drop-down list, choose the appropriate paths returned.

EPNM shows the selected path overlay on the map.
Step 7

Enter the name of the path in the Path Name field.

You can proceed with provisioning the order using the last selected path as explicit path.

Provision EVCs in a Carrier Ethernet Network

Summary of Cisco EPN Manager Carrier Ethernet Provisioning Support

This topic provides a summary of the Carrier Ethernet service provisioning support in Cisco EPN Manager 2.1. For a more detailed overview of the different types of EVCs and the supported underlying networks, see Overview of Circuit/VC Discovery and Provisioning.

Cisco EPN Manager supports provisioning of both port-based and VLAN-based VCs of the following types:

  • E-line—Ethernet Private Line (EPL) and Ethernet Virtual Private Line (EVPL). See E-Line.
  • E-LAN—EP-LAN and EVP-LAN. See E-LAN.
  • E-Access—Access EPL and Access EVPL. See E-Access.
  • E-TREE—EP-TREE and EVP-TREE. See E-Tree.

Cisco EPN Manager supports the following supplementary provisioning functions that can be used during EVC creation:

  • Provision UNIs—For each EVC, you must define the attributes of the participating UNIs. You can either do this during the EVC creation or you can provision a UNI independently of the EVC creation process. See Configure a Device and Interface To Be a UNI.
  • Provision ENNI—For E-Access circuits, you must define the attributes of the ENNI. You can either do this during the EVC creation or you can provision an ENNI independently of the EVC creation process. See Configure a Device and Interface To Be an ENNI.
  • QoS Profiles—You can create QoS profiles to apply to VCs. See Create QoS Profiles.
  • EVC Attribute Profiles—You can create profiles containing all the required attributes for an EVC. These profiles can be selected during EVC creation to define the attributes of the EVC, instead of having to define the attributes individually for each EVC. See Create Circuit/VC Profiles.

Prerequisites for EVC Provisioning

The following prerequisites must be met before you can provision EVCs:

  1. Communication between devices must be set up before you can provision EVCs:
    • In an MPLS end-to-end network, Label Distribution Protocol (LDP) must be set up across the network and each device must be provided with an LDP ID. This enables peer label switch routers (LSRs) in an MPLS network to exchange label binding information for supporting hop-by-hop forwarding. Alternatively MPLS end-to-end connectivity can be achieved using MPLS Traffic Engineering or segment routing, and specifically, EVC provisioning over unidirectional or bidirectional TE tunnels is supported.
    • If there is Ethernet access, i.e., not all devices are MPLS-enabled, G.8032 rings or ICCP-SM must be configured to connect the Ethernet access switch to the MPLS switch.
    • CDP or LLDP must be configured on the links within the G.8032 ring to enable Ethernet link discovery.
  2. To provision EVCs over ICCP-SM and G.8032 networks, all VLANs (from 1 to 4095) should be configured either as primary or as secondary VLANs.
  3. Inventory collection status for the devices on which the EVCs will be provisioned must be Completed . To check this, go to Inventory > Network Devices , and look at the status in the Last Inventory Collection Status column.
  4. Customers can be created in the system so that you can associate a circuit/VC to a customer during the circuit/VC creation and provisioning process. Choose Inventory > Other > Customers in the left sidebar to create and manage customers.
  5. For interfaces to be used in EVCs, it is recommended to reset the default configuration on the interfaces. In global configuration mode, configure the following command on each interface: 
    
default interface 'interface-name’
  6. For ME3600 and ME3800 devices, service instances can only be configured on trunk ports with no allowed VLANs. Configure the following commands on the interface and then re-sync the device in Cisco EPN Manager: 
    interface GigabitEthernetXX/XX
switchport trunk allowed vlan none
switchport mode trunk

Create and Provision a New Carrier Ethernet EVC

EVCs are created in the context of the topology map. You can access the topology map and the Provisioning Wizard by choosing Configuration > Network > Service Provisioning in the left sidebar or you can open the Provisioning Wizard from the topology map, as described in the procedure below.

The process of creating and provisioning an EVC is similar for all supported EVC types and involves:

  • Specifying the endpoints (UNIs and ENNIs) of the EVC.
  • Defining the configuration parameters of the circuit/VC.

After a service is provisioned, you can edit the service and update or change the A-end or Z-end points.

Endpoint modification is supported with E-line services such as EPL and EVPL. you can modify only managed endpoints and full and partial services.

During modification of service, if existing UNI has different device or same device with different port, you can change to other existing UNI.

Some limitations are:

  • You cannot modify the endpoints on both end in a single modification of services.

  • Create an UNI using the standalone UNI wizard and use it in modification of EPL or EVPL services.

  • During modification of service you cannot create a new UNI.

Before you begin

For information about the prerequisites that must be met before you can provision EVCs, see Prerequisites for EVC Provisioning.

To create a new EVC:

Step 6

If you have defined profiles to set the attributes of the different services, select the required profile from the Select Profile drop-down list. See Create Circuit/VC Profiles.

Step 7

Click Next to go to the Service Details page.

Step 8

(Optional) Select the customer for whom the EVC is being created. If there are no customers in the list, go to Inventory > Other > Customers to create the customer in the system, and then restart the Provisioning Wizard.

Step 9

Enter the Service Details. See Service Details Reference for descriptions of the fields and attributes.

Step 10

For E-Line, E-Tree, and E-LAN EVCs: If required, configure the service OAM which enables fault and performance monitoring across the EVC. For E-Line EVCs, select the Enable CFM check box to enable the Service OAM options. You can then choose to either create a new CFM domain or select an existing domain for the E-Line EVC. See Service OAM. Click the Plus icon to add a row to the Service OAM table and provide values in the relevant columns. For E-Tree EVCs, you must specify the direction, i.e., Leaf-to-Root, Root-to-Leaf, or Root-to-Root.

If you want to promote and reconcile point-to-point services or multipoint services, for example EVPL/EPL services, enable the CFM parameters such as CFM Domain name, CFM Domain level and Continuity check interval fields. CFM parameters will be read from the discovered version duirng service promotion. You can perform reconciliation with discovered or provisioned version.
Step 11

In the Deployment Action field, specify what you want to do when the EVC creation process is completed. You can either request a preview of the configurations that will be deployed to the relevant devices before the actual deployment or you can deploy the configurations immediately upon completion.

Step 12

Click Next to go to the page(s) in which you define the UNI(s). In the case of E-Access, there is an additional page for defining the ENNI.

Step 13

Identify the device and interface that will serve as the UNI:

Note 

If one of the endpoints is an interface on a device that is not managed by Cisco EPN Manager, select the Unmanaged check box and provide information for the unmanaged device. See Provision a Circuit/VC with an Unmanaged Endpoint.

  • If you have already configured the required interface on the device as a UNI, uncheck the Create New UNI check box and select the relevant UNI Name from the list.

  • To create a new UNI:

    • Make sure that the Create New UNI check box is checked.
    • In the UNI Name field, enter a name for the UNI that will enable easy identification of the UNI.
    • Select a device from the list in the Device field or click on a device in the map to select it and populate the Device field. A list of the selected device’s ports is displayed.
    • Select the required port from the Port table. If the port cannot be used for the UNI, there is an alert icon next to the UNI name in the Port table that displays the reason why the port cannot be selected.
    Note 
    The device you select during UNI creation is circled in orange in the map. The UNI name is displayed above the orange circle. If it is a point-to-point EVC, the orange circle is labeled to indicate whether it is an A-side or Z-side endpoint.
Step 14

If you are creating a new UNI, enter the New UNI Details. See New UNI Details Reference for descriptions of the fields and attributes.

Step 15

Enter the UNI Service Details. See UNI Service Details Reference for descriptions of the fields and attributes.

Step 16

For E-LAN and E-TREE EVCs with H-VPLS as the core technology, select the devices that will serve as the primary and secondary hubs.

Step 17

For E-Line EVCs: In the Pseudowire Settings page, you can select a TE tunnel over which the EVC will traverse, as follows:

  1. Check the Static Preferred Path check box to assign a static route for the service.

  2. Choose the Preferred Path Type as Bidirectional or Unidirectional or SR Policy.

  3. Select the required bidirectional TE tunnel from the Preferred Path drop-down list. This list contains all existing bidirectional TE tunnels between the endpoints of the EVC.
    Note 

    This field is available only if you selected Bidirectional as the Preferred Path Type.

  4. Select the required unidirectional TE tunnels from the Preferred Path (A-Z) and Preferred Path (Z-A) drop-down lists.
    Note 

    These fields are available only if you selected Unidirectional as the Preferred Path Type.

  5. Select the Allow Fallback to LDP check box if you want the default path to be used if the preferred path is unavailable.
    Note 

    If no tunnel exists between the endpoints, the Preferred Path and the Fallback to LDP options will be disabled.

  6. Select the Send Control Word check box if you want a control word to be used to identify the pseudowire payload on both sides of the connection.

  7. Select theInterworking Option if you need to interconnect sites using either Ethernet, VLAN, or IP. This option must be enabled if one of the endpoints in the EVC is an unmanaged device.

  8. Enter the required bandwidth for the pseudowire.

  9. In the PW ID field, enter an identifier that is dispayed in the Pseudowire settings for point-to- point services.

    Note 
    Pesudowire (PW) ID is automatically allocated from the resource pool of PW ID. You can modify the PW ID value only when you create a service. You cannot edit this value during modification of an EVC service. If the entered PW ID is already allocated to the service then an error message is displayed.
Step 18

(Optional) If you want to append a template with additional CLI commands that will be configured on the devices participating in the service, do so in the Service Template page. See Extend a Circuit/VC Using Templates for more information.

Step 19

When you have provided all the required information for the circuit/VC, click Submit . If you chose to see a preview of the CLI that will be deployed to the devices, it will be displayed now and you can click Edit Attributes to change the attributes. Otherwise, the configurations will be deployed to the devices immediately.

Step 20

Service OAM

On the service level, you can define EOAM (Ethernet Operations, Administration and Management) parameters that will allow monitoring and troubleshooting of the EVC. Effectively, you will be configuring Connectivity Fault Management (CFM) components on the endpoints of the EVC.

For a point-to-point EVC, you can define OAM parameters in one direction, i.e., from UNI A to UNI Z or in both directions. For a multipoint EVC, you can define the source and destination MEP groups and then associate the EVC endpoints with a specific MEP group.

See Configure EOAM Fault and Performance Monitoring for more information about CFM and for device-level CFM configuration.

Use the Service OAM section in the Customer Service Details page of the Provisioning Wizard to define the specifications of the service frame to be monitored and to define the OAM profile to apply to that frame, as follows:
  • From—The source of the traffic flow across the EVC.
  • To—The destination of the traffic flow across the EVC.
  • Direction (E-Tree only) —The direction of traffic flow between leaf and root, or root to root.

Note
Your input in the From and To fields creates MEP groups, or ordered sets of UNIs. In the next page of the wizard, you will associate the UNI with one of these MEP groups.
  • CoS—The Class of Service identifier that should be associated with the frame.
  • OAM Profile—A set of OAM attributes that should be applied to the frame to enable performance monitoring. The following OAM profiles are available for selection:

Configure a Device and Interface To Be a UNI

The User Network Interface (UNI) is the physical demarcation point between the responsibility of the Subscriber (the Customer Edge or CE) and the responsibility of the Service Provider (the Provider Edge or PE).

UNIs demarcate the endpoints of EVCs, so configuring device interfaces as UNIs is an essential part of VC provisioning. UNI configuration can be done during the VC creation process. Alternatively, you can configure UNIs independently of VC creation. These UNIs will be available for selection during VC creation.

To configure a UNI:

Configure a Device and Interface To Be an ENNI

The External Network to Network Interface (ENNI) specifies the reference point that is the interface between two Metro Ethernet Networks (MENs) where each operator network is under the control of a distinct administration authority. The ENNI is intended to support the extension of Ethernet services across multiple operator MENs, while preserving the characteristics of the service.

When provisioning an E-Access VC, you need to define the ENNI that will carry traffic through to the adjacent network. ENNI configuration can be done during the VC creation process. Alternatively, you can configure ENNIs independently of VC creation. These ENNIs will be available for selection during VC creation.

If you chose to see a preview of the CLI before actually deploying to the devices, the preview will be displayed now. Verify the CLI and if you want to change any of the attributes, click Edit Attributes. Else, click Deploy .

Segment Routing

Configure Segment Routing

Segment Routing (SR) is a flexible, scalable way of doing source routing. The source router chooses a path, either explicit or Interior Gateway Protocol (IGP) shortest path and encodes the path in the packet header as an ordered list of segments. Segments represent subpaths that a router can combine to form a complete route to a network destination. Each segment is identified by a segment identifier (SID) that is distributed throughout the network using new IGP extensions.

Each router (node) and each link (adjacency) has an associated SID. Node segment identifiers are globally unique and represent the shortest path to a router as determined by the IGP. The network administrator allocates a node ID from a reserved block to each router. On the other hand, an adjacency segment ID is locally significant and represents a specific adjacency, such as egress interface, to a neighboring router. Routers automatically generate adjacency identifiers outside of the reserved block of node IDs. In an MPLS network, a segment identifier is encoded as an MPLS label stack entry. Segment IDs direct the data along a specified path. A node segment can be a multi-hop path while an adjacency segment is a one-hop path.

Provision Circuits in an Optical/DWDM Network

Summary of Cisco EPN Manager Optical/DWDM Network Provisioning Support

Cisco EPN Manager supports the provisioning of Dense Wavelength Division Multiplexing (DWDM) optical channel (OCH) circuit types. The DWDM optical technology is used to increase bandwidth over existing fiber optic backbones. It combines and transmits multiple signals simultaneously at different wavelengths on the same fiber. In effect, one fiber is transformed into multiple virtual fibers.

Cisco EPN Manager supports the following optical circuits:

  • Dense Wavelength Division Multiplexing (DWDM) optical channel (OCH) circuit—Following are the different optical channel circuit types:

    • Optical Channel Network Connection (OCHNC) WSON—OCHNC WSON circuits establish connectivity between two optical nodes on a specified C-band wavelength. For more information, see Optical Channel Network Connection (OCHNC) WSON.

Prerequisites for Provisioning Optical Circuits

Following are the prerequisites for provisioning an optical circuit:

  • Cisco EPN Manager supports both, Wavelength Switched Optical Network (WSON) and non-WSON circuits. However, for non-WSON circuits, Cisco EPN Manager supports only circuit discovery, which includes circuit overlay, circuit 360 view, multilayer trace view, and circuit details. Cisco EPN Manager does not support the provisioning, activation, deactivation, protection switch actions, and modification of non-WSON circuits.
  • Communication between devices must be set up before you can provision an optical circuit.

  • Inventory collection status for the devices on which the optical circuits will be provisioned must be Completed. To check this, go to Inventory > Device Management > Network Devices, and look at the status in the Last Inventory Collection Status column.

  • DWDM grid unit must be set to either, wavelength or frequency. To do this, go to Administration > Settings > System Settings > Circuits/VCs Display, and under the DWDM Grid Unit area, choose either Wavelength (Nanometer (nm)) or Frequency (Terahertz (THz)).

  • Before you provision an OCHNC or a Media Channel NC circuit using NCS 2000 series devices running on software version 10.7 or later, ensure that you create a UNI config, either in Cisco Transport Controller (CTC) or in Cisco EPN Manager.

  • Optionally, customers must be created in the system so that you can associate a circuit/VC to a customer during the circuit/VC creation and provisioning process. From the left sidebar, choose Inventory > Other > Customers to create and manage customers.

Provision L3VPN Services

Supported L3VPN Services

An MPLS Layer 3 VPN creates a private IP network. The customer connects to the network via customer edge (CE) routers, which act as IP peers of provider edge (PE) routers.

Virtual Routing and Forwarding (VRFs)

On the PE, Virtual Routing and Forwarding (VRF) instances act as virtual IP routers dedicated to forwarding traffic for the L3VPN service. The VRFs learn the routes to each other via the Multi-Protocol Border Gateway Protocol (MP-BGP), and then forward traffic using MPLS.

A VPN is comprised of at least one but typically several VRFs. Cisco EPN Manager uses the VPN ID to discover which VRFs together form a single VPN. If Cisco EPN Manager discovers an existing network where no VPN ID has been provisioned, it takes all VRFs with the same name and associates them into one VPN. For VPNs created using Cisco Prime Provisioning, which uses a naming convention with version number prefixes and different suffixes, Cisco EPN Manager will recognize the different VRFs as belonging to one VPN.

In general there is a regular expression which can be configured to allow for varying naming convention.

Route Targets (RTs)

The connections between VRFs are defined using Route Targets (RTs) that are imported and exported by the VRFs. Cisco EPN Manager makes it easy to set up a full mesh of connections, and automatically allocates the route target to be used. The route target consists of a prefix which is either an AS number or an IPv4 address, for example, a full mesh prefix, 100 [681682]. The prefix can be selected from the existing BGP autonomous system (AS) numbers in the network, or it can be entered manually. The second number following the prefix is allocated automatically by Cisco EPN Manager.

Alternatively or in addition to the full mesh, it is possible to manually select route targets. During VPN creation, there is an initial screen where you type in the route targets to be used within a VPN, and then for each VRF you can select which route targets you import and export. You also specify for which address family (IPv4 or IPv6) you will use the route target. This can be used for example to configure extranets, by importing route targets used in other VPNs.

Route Redistribution

The routes that are exchanged between the PE and the CE have to be redistributed into the MP-BGP routing protocol so that remote endpoints can know which prefixes can be reached at each VRF. To control route redistribution, Cisco EPN Manager allows you to define the required protocol (Static, Connected, or RIP), the protocol's metric value, and optionally the applicable route policy.

Endpoints

Cisco EPN Manager supports the creation of IP endpoints on Ethernet subinterfaces. It supports selecting untagged encapsulation, or specifying an outer and optionally an inner VLAN, with 802.1q or 802.1ad encapsulation. You can specify both IPv4 and Ipv6 addresses at an endpoint. You can also specify the BGP and OSPF neighbor details to provision BGP and OSPF neighbors between CE and PE.

For information on how to provision L3VPN service using Cisco EPN Manager, see, Provision L3VPN Services.

L3VPN Provisioning Features and Limitations

Cisco EPN Manager supports the following L3VPN features:

  • Creation of VRFs.

  • Automatic allocation of Route Target IDs.

  • Automatic allocation of route distinguishers.

  • Discovery of VPNs consisting of several VRFs, based on multiple criteria (VPN ID, common name, and Prime Provisioning naming conventions).

  • You can select devices for L3VPN provisioning using the Point and Click method of provisioning.

  • Definition of IP endpoints attached to a VRF. Associating Ethernet subinterfaces with VRFs.

  • Provisioning of BGP and/or OSPF neighbors between CE and PE.

  • Attaching QoS profiles to the endpoint interfaces.

  • Adding new VRFs to existing VPNs.

  • Modifying VPNs and associated VRFs created and deployed (or discovered and promoted) using Cisco EPN Manager.

  • Overlays in the Network Topology for L3VPN services.

  • Promotion of L3VPN services discovered directly from the device. This further helps in modifying and deleting discovered services.

  • Using route targets with OSPF dual AS routing.

  • Using integrated routing and bridging to provision L3VPN services using BDI/BVI interfaces (subinterfaces).

  • Associating IP Service Level Agreements (SLAs) and CLI templates with L3VPN services.

  • Route redistribution between the PE-CE link and the MP-BGP core using connected, static, RIP, or OSPF routes.

  • Provisioning L3VPN services using LAG interfaces.

  • Provisioning L3VPN services using HSRP.

Cisco EPN Manager has the following L3VPN limitations:

  • VRFs are supported only on Cisco ASR1000, Cisco ASR9000, Cisco ASR90X, Cisco ASR 920X, and Cisco ASR901S devices.

  • You cannot provision multicast VPNs. Only unicast VPNs are supported.

  • While creating the L3VPN service, you can add only up to five VRFs to the VPN. More VRFs can later be added to the VPN using the Modify VRF and Add VRF options.

  • Only one VRF per device is supported. You can create multiple VRFs but on different devices either with the same VRF name or with different VRF names.

  • Route policies can be selected but cannot be defined within the L3VPN service.

  • Only BGP, OSPF, and OSPFv3 routing protocols are supported in PE-CE.

  • There is no support for multiple attached PEs, and so there is no Site of Origin support.

  • Deleting an L3VPN service deletes the IP SLA operations associated with the service from the device. And the associated operations that are deleted will not be available for future usage.

  • The Integrated Routing and Bridging (IRB) is not supported for Cisco Catalyst 6500 series switches..

Prerequisites for L3VPN Provisioning

For more information about implementing L3VPNs, see Implementing MPLS Layer 3 VPNs.

Before you begin provisioning L3VPN services, ensure that the following pre-requisites are followed.

Following are the prerequisites for provisioning an L3VPN service:

  • BGP must be set up on all devices. Typically all devices must communicate with each other via a pair of route reflectors.

  • Pre-configuration changes required to set up BGP:

    Configure the BGP router-id as shown in the example below: 

    router bgp 65300
		  bgp router-id 1.1.1.1

    Set Vpn4 and Vpn6 as the parent address family using these commands: 

    
			 router bgp 100
		  address-family vpnv4 unicast 
		  address-family vpnv6 unicast
  • MPLS reachability must be set up between the devices. MPLS core network configuration must be set up.
  • Inventory collection status for the devices on which the L3VPN services will be provisioned must be 'Completed'. To check the status of devices, go to Inventory > Network Devices, and look at the status in the Last Inventory Collection Status column.
  • (Optional) Customers must be created in the system so that you can associate the L3VPN service to a customer during L3VPN service provisioning. To create and manage customers, choose Inventory > Other > Customers.

L3VPN Service Discovery

Cisco EPN Manager associates multiple VRFs into a single VPN using multiple criteria:

  • If VRFs were configured with a VPN ID: then the VPN service is discovered using the VPN ID to identify the VRFs that belong to the same VPN. If you have VPNs that you need to discover, where different VRF names are used within one VPN, then Cisco EPN Manager discovers the VRFs by the VRF names.

    In cases where no more than one VRF is created per device, it is common practice to simply use the same VRF name everywhere across the VPN. If Cisco EPN Manager sees multiple VRFs with the same name and no VPN ID, then it considers them as a single VPN, and the VPN name will be the name of the VRFs.

  • If VPNs that were originally provisioned using Prime Provisioning: Cisco EPN Manager is also aware of the Prime Provisioning VRF naming convention. The naming convention used by Prime Provisioning is in the format:

    V<number>:<VPN name><optional suffix, one of -s -h -etc>

    VRFs with the same names and numbers will belong to the same VPN. For example these are VRFs belonging to a VPN called 'ABC':

    V1:ABC, V2:ABC, V4:ABC-s, V22:ABC-h, V001:ABC, etc.

  • If the VRF has no VPN ID: and has a unique name that doesn't match other names according to the Prime Provisioning convention, it will be placed into a VPN on its own. The name of the VPN will be the name of the VRF.

The Prime Provisioning naming convention feature is driven by a regular expression that is embedded in the product. If configuring a VPN is not an option for you and you have a naming convention that could be matched with a regular expression, it is possible to change it. To change the regular expression, please contact your Cisco Advanced Services representative.

Create and Provision a New L3VPN Service

The process of creating and provisioning a unicast L3VPN involves:

  • (Optional) Associating a customer to the VPN.

  • Defining the attributes that influence how traffic that is delivered over the L3VPN and through its endpoints will be treated.

  • Specifying the endpoints and route redistribution values of the L3VPN.

  • (Optional) Configuring IP Service Level Agreements (SLAs) operation to monitor end-to-end response time between devices using IPv4 or IPv6.

  • (Optional) Associating user defined CLI templates with the L3VPN service.

Note: Only Unicast L3VPN services are supported in this release.

To create a new L3VPN service:

Procedure

Step 1

From the left pane, choose Maps > Topology Maps > Network Topology.

The network topology window opens.

Step 2

From the toolbar, click Device Groups and then select the group of devices you want to show on the map.

Step 3

Click the Circuits/VCs tab, then click the + (Create) icon in the Circuits/VCs pane toolbar.

The Provisioning Wizard opens in a new pane to the right of the map. You can also access the L3VPN Provisioning wizard by choosing Configuration > Network > Service Provisioning.

Step 4

From the Technology drop-down list, select L3VPN. A list of supported L3VPN service types is displayed.

Step 5

In the Service Type section, choose Unicast and click Next to enter the customer and service details. In this release, only service type Unicast L3VPN is supported.

Step 6

(Optional) Select the customer that you want to associate with the VPN. If there are no customers in the drop-down list, you can go to Inventory > Other > Customers to create the customer and return to this step.

Step 7

Specify the basic L3VPN parameters:

  1. Use the Activate check box to specify whether the service must be in active (check box enabled) or inactive (check box disabled) state. The Active state enables traffic to pass through the circuit and automatically sets the Service State for all associated IP endpoints to True. In the Inactive state, you can choose to set the service state for IP endpoints to true or false.

  2. Provide a unique name for the service and optionally enter a description

  3. Enter a unique VPN ID for the service. The VPN ID must be in the format OUI:VPN Index. For example, 36B:3. Here, 36B is the Organization Unique Identifier (OUI) and 3 is the VPN Index.

  4. In the IP MTU field, enter a value between 1522 (default) and 9216. The service MTU is the size in bytes of the largest IP packet that can be carried unfragmented across the L3VPN. It does not include layer 2 headers.

    The configured interface MTU is the service MTU plus the size of any layer 2 headers. For Ethernet, this will add 14 bytes plus 4 bytes per VLAN header.

    The value of the UNI MTU depends on the service MTU and outer and inner VLAN values:

    • If both outer and inner VLANs are present, then the UNI MTU value is greater than the Service MTU + 14 + (4*2)

    • If only the outer VLAN is present, then the UNI MTU value is greater than the Service MTU + 14 + (4 *1)

    • If no VLANs are present, then the UNI MTU value is greater than the Service MTU + 14

  5. (Optional) To create a full mesh topology for this service, select the Create Full Mesh check box and enter the full mesh prefix manually in the New Prefix field or select a value from the Existing Prefix drop-down list. The available options depend on the full mesh prefix values discovered from the selected device.

  6. Select the address family as IPv4, IPv6, or Both from the Full Mesh Address Family drop-down list.

Step 8

Use the Route Target Allocation section to manually specify the route target address families (IPv4, IPv6, or Both) and their associated route target values. You can create multiple route targets for the L3VPN service. These route targets can be associated with any VRF that you attach to this L3VPN service in the following steps.

Note 
The route targets associated with a VRF must also be associated with the L3VPN the VRFs belong to.
Note 
The configured route policy is listed in the Export drop-down list of the route policy.
Step 9

In the Deployment Action drop-down menu, specify the task that must be taken up when the service creation process is completed. Your options are:

  • Preview: allows you to review the configuration that is generated before it is deployed to the device.

  • Deploy: allows you to deploy the configuration to the relevant devices immediately upon completion.

Step 10

  1. Click the '+' icon to add the VRF details manually. To auto populate the VRF details, click the respective device on the map. The device details and a new name for the VRF are automatically populated on the Add VRFs page.

  2. To manually specify the VRF details, select the required device from the Device drop-down list. You can then manually enter the VRF name and description, and check the RD Auto check box.

    Note 

    If multiple VRFs are created on the same device, you must name them differently to ensure that they are not part of the same VPN. You cannot create multiple VRFs with the same names on the same device.

Step 12

Specify the IPv4 and IPv6 route targets and route distribution details:

  1. Route Targets: Select the route targets for this VRF from the Route Target drop-down menu. The options in this drop-down menu are available based on the route targets associated with this service in Step 7.

  2. Select the direction in which the route targets must be applied. Depending on the device you select, choose Import, Export, Both, or None.

    Choose the directions depending on the type of device that is selected. For example, for Cisco IOS-XR devices, you cannot choose 'None' as the route target direction.

  3. In the Route Policy section, select the import and export policy for the route targets.

    Note 

    Route Policy which has Opaque Extended Community attached is applicable only for export.

  4. In the Route Distribution section, specify the protocol that must be associated with the VRF, the protocol's metric value, the routing process ID, the relevant route policies and the route match type.

    • Protocol- Choose the source protocol from which routes must be redistributed. Your options are Static, Connected, RIP, and OSPF.

    • Metric- (Optional) Enter a numeric value for the metric which is used when redistributing from one routing process to another process on the same router.

    • Routing Process ID- (applicable only to OSPF and RIP) Specify the unique numerical value that identifies the instance of the routing process on the device.

    • Route Policy- (Optional) Select one of the route policies present on the selected device. You cannot create route policies using Cisco EPN Manager.

      Note 

      Route Policy which has Opaque Extended Community attached cannot be used in Redistribute.

    • Route Match Type (applicable only to OSPF)- Specify the match type that must be associated with the selected route policy. Your options are: Internal, External, External 1, External 2, NSSA External, NSSA External 1, NSSA External 2, NSSA, Level 1, Level 2, and Level Inter Area.

Step 13

Specify the IP endpoints and UNIs values manually as follows:

  • If the endpoint interface has already been configured as a UNI, uncheck the New UNI check box and select the required UNI from the UNI Name drop-down list.

  • To create a new UNI:

    1. Select the New UNI check box.

    2. In the UNI Name field, enter a unique name for the UNI.

    3. In the Device drop-down, select the device, its required interface, and provide a description for the UNI.

    4. Check the Service Multiplexing check box to enable more than one L3VPN or Carrier Ethernet service to be supported at the UNI.

    5. Specify the IP Maximum Transmission Unit (MTU) for the UNI., the speed and duplex settings for the UNI.

    6. Either check the Auto Negotiation check box to automatically adjust the speed and duplex settings for the UNI or uncheck the Auto Negotiation check box and specify the speed and duplex settings manually.

    7. Choose the UNI QoS profiles for ingress or egress traffic on the UNI. The list of profiles includes policy maps that were configured on the device and discovered by the system, as well as user-defined QoS profiles. If you select a UNI QoS profile, you cannot add individual QoS policies to the service endpoint in the upcoming steps. If you want to add specific QoS policies to the endpoint, leave the UNI Ingress and Egress QoS Profile fields blank.

      Note 

      You can choose two different discovered QoS profiles for the ingress and egress directions, however, in case of user defined QoS profiles, only a single QoS profile can be chosen for both directions.

    8. Select Enable Link OAM to enable IEEE 803.1ah link operation and maintenance. If Link OAM is enabled, you will see events relating to the state of the link between this UNI and the customer’s access switch.

    9. Select Enable Link Management to enable the customer access switch to get information about this UNI, VLAN IDs, services on the UNI, and so on.

For a detailed description of the fields and attributes in the UNI table, see New UNI Details Reference.

Step 14

Specify the service end point to be associated with the L3VPN by providing the following details, and then click Next:

  • VRF Name: Choose one of the available VRFs that can be associated with this VPN.

  • IPv4 and IPv6 address: Enter the IP addresses and network masks of the service end point. The masks can be entered simply as an integer that represents the length of the network mast (or in CIDR format).

  • VLAN and Inner VLAN: Enter the inner and outer VLAN identifiers using integers between 1 and 4094. Inner VLAN is the identifier for the second level of VLAN tagging.

  • QoS Policy: (Optional) Select the QoS policy that must be applied to the service endpoint. This field is disabled if you have associated UNI Ingress/Egress QoS profiles to the service in the above step. For information on creating QoS profiles, see Configure Quality of Service (QoS).

    Note 

    You can choose two different discovered QoS policies for the ingress and egress directions, however, in case of user defined QoS policies, only a single QoS policy can be chosen for both directions.

  • Service State: Specify whether the service state for associated IP endpoints must be set to true or false. If the L3VPN is in Activate state (specified in Step 6 above), this check box is disabled and all service state values are automatically set to True.

  • Use Integrated Routing & Bridging: Specify whether the VRF and IP addresses must be configured under the sub-interfaces or under the BVI (virtual) interfaces.

    Note 

    This check box is enabled only when you select devices such as, Cisco ASR 90XX devices, that support integrated routing and bridging. For Cisco ASR90xx and other IOS-XE devices you cannot uncheck the Use Integrated Routing & Bridging check box because configuration is taken care by the BDI interface..

  • (Optional) Check the Enable HSRP check box to specify the HSRP details. See HSRP Details Reference

Step 15

Click Next to go to the PE-CE Routing page.

Step 16

Click the '+' icon to add the PE-CE routing details. See PE-CE Routing Details References.

Step 17

(Optional) Select existing IP SLA parameters from the list, or specify the IP SLA operation parameters described in the table below and then click Next.

IP SLA Settings

IP SLA Parameters

Descriptions

Operation Settings

Name

Enter a unique name to identify the IP SLA operation for the selected L3VPN service.

Type

Select the type of IP SLA operation that must be generated for the devices participating in this L3VPN service. Your options are:

  • UDP Echo: Configures an IP SLAs User Datagram Protocol (UDP) Echo operation to measure response times and to test end-to-end connectivity between a Cisco device and devices using IPv4 or IPv6.

  • ICMP Echo: Allows you to measure end-to-end network response time between a Cisco device and other devices (source and destination values, as described below) using IPv4 or IPv6. With an IP SLA operation of type ICPM Echo, you cannot associate the 'Connection Loss' action variable.

  • UDP Jitter: Configures the UDP jitter operation which analyzes round-trip delay, one-way delay, one-way jitter, one-way packet loss, and connectivity in networks that carry UDP traffic in IPv4 or IPv6 networks.

Source

Specify the device which acts as the source point from which the IP SLA configuration is generated. The IP SLA responses are generated based on the connectivity between this source device and the target device. The VRF values for this operation are automatically selected based on your Source selection.

Source Port

Enter a numeric value between 0 and 65535 to specify the source port value for which the IP SLA operation must be configured.

Destination

Specify the device which acts as the target point from which the IP SLA configuration is generated. The IP SLA responses are generated based on the connectivity between the source device and this target device.

Destination Port

Enter a numeric value between 0 and 65535 to specify the destination port value for which the IP SLA operation must be generated.

VRF

The VRF details are automatically selected based on the device you specify as the IP SLA operation Source.

Reaction Settings

Action Variable

Select the variable based on which the IP SLA reactions must be triggered. For example, when a monitored value exceeds or falls below a specified level, or when a monitored event (such as a timeout or connection loss) occurs.

  • Connection Loss: Indicates that an event must be triggered when a connection loss occurs. This value is not displayed if you select ICPM Echo as the type of operation.

  • Round Trip Time: If you choose this action variable, you need to enter the Upper Threshold Value and the Lower Threshold Value which indicates that an event must be triggered when a monitored value exceeds or falls below the upper and lower threshold values that you specify.

  • Time Out: Indicates that an event must be triggered after a given set of consecutive timeouts occur.

  • Verify Error: Indicates that an event must be triggered after an error of type 'VerifyError' occurs.

Action Type

Select one of the following actions that must be taken based on the conditions set in the Action Variable field:

  • None: No action is taken.

  • Trap and Trigger: Triggers both an SNMP trap and starts another IP SLAs operation when the violation conditions are met, as defined in the Trap Only and Trigger Only options below.

  • Trap Only: Sends an SNMP logging trap when the specified violation type occurs for the monitored element.

  • Trigger Only: Changes the state of one or more target operation's Operational state from 'pending' to 'active' when the violation conditions are met. A target operation will continue until its life expires (as specified by the target operation's configured lifetime value). A triggered target operation must finish its life before it can be triggered again.

Threshold Type

Select the threshold type based on which the IP SLA events are generated.

  • Average: If you choose this threshold type, enter the N Value which specifies that an event must be triggered when the averaged total value of N probes is reached either when specified upper-threshold value is exceeded, or when it falls below the lower-threshold value.

  • Consecutive: If you choose this threshold type, enter the Consecutive Values as part of the reaction settings. This threshold type triggers an event only after a violation occurs a specified number of times consecutively. For example, if you enter 5 as the consecutive value, the consecutive violation type is used to configure an action to occur after a timeout occurs 5 times in a row, or when the round-trip-time exceeds the upper threshold value 5 times in a row.

  • Immediate: Triggers an event immediately when the value for a reaction type (such as response time) exceeds the upper threshold value or falls below the lower threshold value, or when a timeout, connection loss, or verify error event occurs.

  • Never: Never triggers an event.

  • X out of Y occurrences: If you choose this threshold type, enter the X Values and Y Values to specify the number of occurrences. This triggers an event after some number (x) of violations within some other number (y) of probe operations (x of y).

Simple Schedule

-

Enter the scheduling parameters for an individual IP SLAs operation by entering the following values:

  • Frequency: Enter the elapsed time within which the operation must repeat, in seconds.

  • Life Time: Enter the overall time until when the operation must be active, in seconds. A single operation repeats at the specified frequency for the lifetime of the operation.

  • Age Out: Enter the length of time to keep an operation active, in seconds. For example, an age out value of 43200 will ensure that the operation will age out after 12 hours of inactivity.

  • Start Now and Start After: Enable the Start Now check box to schedule the IP SLA operation to be executed immediately on Save. Or use the Start After field to specify the number of minutes after which the operation can be executed.

Step 18

(Optional) Use the Service Template page to append a template with additional CLI commands that will be configured on the devices participating in the service. See Extend a Circuit/VC Using Templates for more information.

Step 19

When you have provided all the required information for the service, click Submit. If you chose to see a preview of the CLI that will be deployed to the devices, it will be displayed now and you can click Edit Attributes to change the L3VPN attributes. Otherwise, the configurations will be deployed to the devices immediately.

In case of a deploy failure on even a single device that is part of the service, the configuration is rolled back on all devices participating in the service. To delete the endpoints associated with the service, see, Delete an L3VPN Service Endpoint. To add more VRFs to this L3VPN service, see Add and Copy VRFs to an L3VPN Service.

HSRP Details Reference

Hot Standby Router Protocol (HSRP) is Cisco’s standard method of providing high network availability by providing first-hop redundancy for IP hosts on an IEEE 802 LAN configured with a default gateway IP address. Hot Standby Router Protocol (HSRP) provides redundancy for IP networks, ensuring that user traffic immediately and transparently recovers from first hop router failures. HSRP allows multiple routers on a single LAN to share a virtual IP and MAC address which is configured as the default gateway on the hosts. From the group of routers configured in an HSRP group, there is one router elected as the active router and another as a standby router. The active router assumes the role of forwarding packets sent to the virtual IP address. If the active router fails, the standby router takes over as the new active router. In Cisco EPN Manager, HSRP for IPv4 is supported on switches running the IP base or IP services image and HSRP for IPv6 is supported on unicast routing. HSRP is not supported in IOS-XE devices for address family IPv6. The following table lists and describes the attributes of HSRP.

Table 12. HSRP Settings

Attribute

Description

Group Number

Enter the standby group number of either IOS-XE or IOS-XR device. The recommended range values are:

  • IOS-XE—Range value must be between 1-255.

  • IOS-XR—Range value must be between 1-4095.

Virtual IP

Enter the IPv4/IPv6 address. Ensure that the Virtual IP address and SEP address should be entered within the same subnet.

Priority

Enter the priority to decide which router is to be the primary router.

Hello Timer

Enter the time between hello packets in seconds.

Note 
Hold Timer and Reload Delay values should be entered mandatorily for IOS-XR device for the specified Hello Timer and Minimum Delay values.

Minimum Delay

Enter the minimum delay time in seconds..

Preempt Minimum Delay

Specify the preempt delay on the router.

Authentication Key

Enter the authentication key if the group number is between 1 to 255. This will allow the authentication messages to be included in the HSRP multicast. This ensures that only authorized routers can become part of the HSRP group.

Hold Timer

Enter the hold time in seconds.

Note 
Hold down time should be more than hello timer for XE device.

Reload Delay

Enter the delay time to reload.

Preempt Reload Delay

Enter the preempt reload delay.

This field is not supported for IOS-XR device.

Provision Circuit Emulation Services

Summary of Cisco EPN Manager CEM Provisioning Support

Cisco EPN Manager supports the provisioning of Circuit Emulation (CEM) services. CEM provides a bridge between the traditional TDM network and the packet switched network (PSN). It encapsulates the TDM data into packets, provides appropriate header, and send the packets through PSN to the destination node. For more information, see Supported Circuit Emulation Services.

You can also assign a MPLS TE tunnel to a CEM service to allow the CEM service to traverse through the network. Use the Preferred Path drop-down list in the Provisioning Wizard to assign a MPLS TE tunnel for a CEM service. For more information, see CEM Service Details References.

Prerequisites for CEM Provisioning

The following prerequisites must be met before you can provision a CEM service:

  • IP/MPLS connectivity must be enabled on the originating and terminating endpoints in a CEM service.
  • CEM configurations such as loopback interface and ACR groups must be configured on the devices that will be used in the CEM service. For more information, see Configure Circuit Emulation.
  • Inventory collection status for the devices on which the CEM service will be provisioned must be Completed. To check this, go to Inventory > Device Management > Network Devices, and look at the status in the Last Inventory Collection Status column.
  • Optionally, customers can be created in the system so that you can associate a CEM service to a customer during the service creation and provisioning process. From the left sidebar, choose Inventory > Other > Customers to create and manage customers.

Create and Provision a New CEM Service

The process of creating and provisioning a CEM service in Cisco EPN Manager involves:
  • Specifying endpoints of the CEM service.
  • Defining the attributes that influence how traffic that is delivered over the CEM service and through its endpoints will be treated.

Before you begin

For information about the prerequisites that must be met before you can provision a CEM service, see Prerequisites for CEM Provisioning.

Procedure

Step 1

In the left sidebar, choose Maps > Topology Maps > Network Topology.

Step 2

Click Device Groups, and then select the location in which you want to create the CEM service.

Step 3

Close the Device Groups popup window.

Step 4

In the Network Topology window, click Circuits/VCs.

Step 5

Click the '+' icon to open the Provisioning Wizard in a new pane to the right of the map.

You can also access the Provisioning wizard by choosing Configuration > Network > Service Provisioning.

Step 6

From the Technology drop-down list, choose Circuit Emulation.

Step 7

From the Service Type drop-down list, choose the required CEM service type depending on the rate at which you want the circuit to transmit the data. For a list of CEM service types that Cisco EPN Manager supports, see Supported Circuit Emulation Services.

Step 8

If you have defined profiles to set the attributes of the different services, select the required profile from the Select Profile drop-down list. See Create Circuit/VC Profiles.

Step 9

Click Next to go to the Customer Service Details page.

Step 10

(Optional) Select the customer for whom the EVC is being created. If there are no customers in the list, go to Inventory > Other > Customers to create the customer in the system, and then go to the Provisioning Wizard to start provisioning the CEM service.

Step 11

Check the Activate check box to activate the interface associated with the service that you are provisioning.

Step 12

Enter the service name and its description.

Step 13

In the Deployment Action field, specify what you want to do when the CEM service creation process is completed. You can either request a preview of the configurations that will be deployed to the relevant devices before the actual deployment or you can deploy the configurations immediately upon completion.

If you choose Deploy, then click one of the following deployment options:

  • Deploy Now—Directly deploys the provisioning order

  • Deploy Later—Saves the created provisioning order and deploys the same order at later period of time.

  • Schedule Deployment—Schedules the provisioning order and to be deployed at the scheduled time. If you click this Schedule Deployment radio button, specify the following:

    • Deploy Schedule Time—Specify a schedule time for deployment of provision order.

    • Server Time—Displays the current server time.
Step 14

Click Next, and then enter the A End and Z End configurations, and the transport settings for the CEM service. See CEM Service Details References for descriptions of the fields and attributes.

Step 15

If one of the endpoints is an interface on a device that is not managed by Cisco EPN Manager, check the Unmanaged Device check box and provide information for the unmanaged device. See Provision a Circuit/VC with an Unmanaged Endpoint for more information.

Note 

The Unmanaged Device check box is available only in the Z End Configurations page.

Step 16

(Optional) If you want to append a template with additional CLI commands that will be configured on the devices participating in the service, do so in the Template Details page. See Extend a Circuit/VC Using Templates for more information.

Step 17

When you have provided all the required information for the service, click Submit. If you chose to see a preview of the CLI that will be deployed to the devices, it will be displayed now and you can click Edit Attributes to change the attributes. Otherwise, the configurations will be deployed to the devices immediately.

The CEM service should be added to the list in the Circuits/VCs pane in the Network Topology window To check the provisioning state, click on thei icon next to the circuit/VC name to see the Circuit/VC 360 view. Also, you can view the saved provisioning job in the Planned Circuits/VCs tab from Administration > Dashboards > Job Dashboard > Provisioning.

CEM Service Details References

The following table lists and describes the attributes that define the CEM service types.

Table 15. Circuit Section Reference—CEM Service Types

Attribute

Description

A End and Z End Configurations

Device

Name of the source and destination devices in the CEM service.

Working Path and Protecting Path
Note 

The Working Path and Protecting Path are not available for X.21, C37.94, and EM-Voice service types.

Port Name or Interface Name

Name of the interface on the source and destination devices in the CEM service. You can choose either the port name or the port group.

When you choose the port name under the Protecting Path area, the unidirectional path switched ring (UPSR) protection mechanism is enabled.

When you choose the port group under the Protecting Path area, the Automatic Protection Switching (APS) protection mechanism is enabled. For more information about how to configure protection groups, see Configure APS or MSP and UPSR or SNCP Protection Groups.

Higher Order Path

When a SONET/SDH line is channelized, it is logically divided into smaller bandwidth channels called higher order paths (HOP) and lower order paths (LOP). HOP or synchronous transport signal (STS) path is used to transport TDM data of higher bandwidth. HOPs can also contain LOPs within it.

Select the path and path mode available for the CEM service.

Lower Order Path

LOPs or virtual tributary (VT) path is used to transport TDM data of lower bandwidth.

DS0 Time Slot

Choose one or more time slots available in the DS0 group.

Note 

This field is available only if you select DS0 in the Service Type field.

Clocking

The nodes in a network may be at different clock rates. Differences in timing at nodes may cause the receiving node to either drop or reread information sent to it. Clocking is essential to synchronize all nodes to the same clock rate. For more information about clocking, see Configure Clocking for CEM.

Clock Source

Enables to recover the clock rate from single source so that all nodes can be synchronized at the same clock rate. Values are:

  • Internal – Clock rate recovered from the host.

  • Line – Clock rate recovered from the SONET/SDH line.

  • Adaptive Clock Recovery – Clock rate is recovered based on the dejitter buffer fill level. Due to delay variations, the dejitter buffer fill levels keep varying continuously. The TDM service clock is recovered after filtering the variations. The accuracy of the recovered clock depends on the delay variations.

  • Differential Clock Recovery – Clock rate is recovered from a primary clock using Sync-E. For more information about how to setup the primary clock for your network, see Synchronize the Clock Using Sync-E, BITS, and PTP.

Clock Rate

Select the required clock rate in bits per second (bps). For example, if the clock rate is set to 64000, you can only send 64 kbps over the serial interface.

Note 

This field is available only for X.21 service type.
QOS

The list of profiles available for selection includes policy maps that were configured on the device and discovered by the system, as well as user-defined QoS profiles. Refer to Create QoS Profiles for information on how to create QoS profiles.

Ingress QoS Profile

Select the ingress QoS policies that are configured on the A end and Z end devices.
Note 

The Ingress QoS Profile is not available for X.21, C37.94, and EM-Voice service types.
