Command History

Release Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

The member command specifies the two members of the Virtual Private Wired Service (VPWS), multisegment pseudowire or local connect services. For VPWS, one member is an attachment circuit and the other member is a pseudowire interface. For a multisegment pseudowire, both members are pseudowire interfaces. For local connect, both members are active interfaces.

When both the pseudowire interface and the peer information are specified, an interface is dynamically created by using the interface-number argument specified in the pseudowire command.

Configure the group name to specify which of the two possible groups a member belongs to.

Configure a priority for each member so that the active members can be chosen based on priority when there are multiple redundant members. The default priority for a member is 0 (highest).

There can only be two groups, with a maximum of four members in one group and only one member in the other group (the lone member is for active redundancy and the other three are for backup redundancy). If a group name is not specified, only two members can be configured in the L2VPN cross-connect context.

Examples

The following example shows how to specify pseudowire as the attachment circuit type:

Device> enable
Device# configure terminal
Device(config)# l2vpn xconnect context con1
Device(config-xconnect)# member pseudowire 17

mpls label range

To configure the range of local labels available for use with Multiprotocol Label Switching (MPLS) applications on packet interfaces, use the mpls label range command in global configuration mode. To revert to the platform defaults, use the no form of this command.

mpls label range minimum-value maximum-value [static minimum-static-value maximum-static-value]

no mpls label range

Syntax Description

minimum-value

The value of the smallest label allowed in the label space. The default is 16.

maximum-value

The value of the largest label allowed in the label space. The default is platform-dependent.

static

(Optional) Reserves a block of local labels for static label assignments. If you omit the static keyword and the minimum-static-value maximum-static-value arguments, no labels are reserved for static assignment.

minimum-static-value

(Optional) The minimum value for static label assignments. There is no default value.

maximum-static-value

(Optional) The maximum value for static label assignments. There is no default value.

Command Default

The platform’s default values are used.

Command Modes

Global configuration

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

The labels 0 through 15 are reserved by the IETF (see RFC 3032, MPLS Label Stack Encoding, for details) and cannot be included in the range specified in the mpls label range command. If you enter a 0 in the command, you will get a message that indicates that the command is an unrecognized command.

The label range defined by the mpls label range command is used by all MPLS applications that allocate local labels (for dynamic label switching, MPLS traffic engineering, MPLS Virtual Private Networks (VPNs), and so on).

You can use label distribution protocols, such as Label Distribution Protocol (LDP), to reserve a generic range of labels from 16 through 1048575 for dynamic assignment.

You specify the optional static keyword, to reserve labels for static assignment. The MPLS Static Labels feature requires that you configure a range of labels for static assignment. You can configure static bindings only from the current static range. If the static range is not configured or is exhausted, then you cannot configure static bindings.

The range of label values is 16 to 4096. The maximum value defaults to 4096. You can split for static label space between say 16 to 100 and for dynamic label space between 101 to 4096.

The upper and lower minimum static label values are displayed in the help line.

Examples

The following example displays the help lines when you configure the dynamic label with a minimum value of 16 and a maximum value of 100:


Device(config)# mpls label range 16 100 static ?
<100>  Upper Minimum static label value
<16>         Lower Minimum static label value
Reserved Label Range  --> 0    to 15
Available Label Range --> 16   to 4096
Static Label Range    --> 16   to 100
Dynamic Label Range   --> 101  to 4096

The following example shows how to configure a static range from 16 to 100. If the lower minimum static label space is not available, the lower minimum is not displayed in the help line.


Device(config)# mpls label range 16 100 static ?
  <16-100>  static label value range

The following example shows how to configure the size of the local label space. In this example, the minimum static value is set to 200, and the maximum static value is set to 4000.


Device# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Device(config)# mpls label range 200 4000
Device(config)#

If you had specified a new range that overlaps the current range (for example, the new range of the minimum static value set to 16 and the maximum static value set to 1000), then the new range takes effect immediately.

The following example show how to configure a dynamic local label space with a minimum static value set to 100 and the maximum static value set to 1000 and a static label space with a minimum static value set to 16 and a maximum static value set to 99:


Device(config)# mpls label range 100 1000 static 16 99
Device(config)#

In the following output, the show mpls label range command, executed after a reload, shows that the configured range is now in effect:


Device# show mpls label range 	
Downstream label pool: Min/Max label: 100/1000
Range for static labels: Min/Max/Number: 16/99

The following example shows how to restore the label range to its default value:


Device# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Device(config)# no mpls label range 
Device(config)# end

mpls label protocol (interface configuration)

To specify the label distribution protocol for an interface, use the mpls label protocol command in interface configuration mode. To remove the label distribution protocol from the interface, use the no form of this command.

mpls label protocol ldp

no mpls label protocol ldp

Syntax Description

ldp

Specifies that the label distribution protocol (LDP) is to be used on the interface.

Command Default

If no protocol is explicitly configured for an interface, the label distribution protocol that was configured for the platform is used. To set the platform label distribution protocol, use the global mpls label protocol command.

Command Modes

Interface configuration (config-if)

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

To successfully establish a session for label distribution for a link connecting two label switch routers (LSRs), the link interfaces on the LSRs must be configured to use the same label distribution protocol. If there are multiple links connecting two LSRs, all of the link interfaces connecting the two LSRs must be configured to use the same protocol.

Examples

The following example shows how to establish LDP as the label distribution protocol for the interface:


Device(config-if)# mpls label protocol ldp

mpls label protocol (global configuration)

To specify the Label Distribution Protocol (LDP) for a platform, use the mpls label protocol command in global configuration mode. To restore the default LDP, use the no form of this command.

mpls label protocol ldp

no mpls label protocol ldp

Syntax Description

ldp

Specifies that LDP is the default label distribution protocol.

Command Default

LDP is the default label distribution protocol.

Command Modes

Global configuration

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

If neither the global mpls label protocol ldp command nor the interface mpls label protocol ldp command is used, all label distribution sessions use LDP.

Examples

The following command establishes LDP as the label distribution protocol for the platform:


Device(config)# mpls label protocol ldp

mpls ip (interface configuration)

To enable Multiprotocol Label Switching (MPLS) forwarding of IPv4 and IPv6 packets along normally routed paths for a particular interface, use the mpls ip command in interface configuration mode. To disable this configuration, use the no form of this command.

mpls ip

no mpls ip

Syntax Description

This command has no arguments or keywords.

Command Default

MPLS forwarding of IPv4 and IPv6 packets along normally routed paths for the interface is disabled.

Command Modes

Interface configuration (config-if)

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

MPLS forwarding of IPv4 and IPv6 packets along normally routed paths is sometimes called dynamic label switching. If dynamic label switching has been enabled for the platform when this command is issued on an interface, label distribution for the interface begins with the periodic transmission of neighbor discovery Hello messages on the interface. When the outgoing label for a destination routed through the interface is known, packets for the destination are labeled with that outgoing label and forwarded through the interface.

The no form of this command causes packets routed out through the interface to be sent unlabeled; this form of the command also terminates label distribution for the interface. However, the no form of the command does not affect the sending of labeled packets through any link-state packet (LSP) tunnels that might use the interface.

Examples

The following example shows how to enable label switching on the specified Ethernet interface:


Device(config)# configure terminal
Device(config-if)# interface TenGigabitEthernet1/0/3
Device(config-if)# mpls ip

The following example shows that label switching is enabled on the specified vlan interface (SVI) on a Cisco Catalyst switch:


Device(config)# configure terminal
Device(config-if)# interface vlan 1
Device(config-if)# mpls ip

mpls ip (global configuration)

To enable Multiprotocol Label Switching (MPLS) forwarding of IPv4 and IPv6 packets along normally routed paths for the platform, use the mpls ip command in global configuration mode. To disable this feature, use the no form of this command.

mpls ip

no mpls ip

Syntax Description

This command has no arguments or keywords.

Command Default

Label switching of IPv4 and IPv6 packets along normally routed paths is enabled for the platform.

Command Modes


Global configuration

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

MPLS forwarding of IPv4 and IPv6 packets along normally routed paths (sometimes called dynamic label switching) is enabled by this command. For a given interface to perform dynamic label switching, this switching function must be enabled for the interface and for the platform.

The no form of this command stops dynamic label switching for all platform interfaces regardless of the interface configuration; it also stops distribution of labels for dynamic label switching. However, the no form of this command does not affect the sending of labeled packets through label switch path (LSP) tunnels.

Examples

The following example shows that dynamic label switching is disabled for the platform, and all label distribution is terminated for the platform:


Device(config)# no mpls ip

mpls ip default-route

To enable the distribution of labels associated with the IP default route, use the mpls ip default-route command in global configuration mode.

mpls ip default-route

Syntax Description

This command has no arguments or keywords.

Command Default

No distribution of labels for the IP default route.

Command Modes

Global configuration

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

Dynamic label switching (that is, distribution of labels based on routing protocols) must be enabled before you can use the mpls ip default-route command.

Examples

The following example shows how to enable the distribution of labels associated with the IP default route:


Device# configure terminal
Device(config)# mpls ip
Device(config)# mpls ip default-route

neighbor (MPLS)

To specify the peer IP address and virtual circuit (VC) ID value of a Layer 2 VPN (L2VPN) pseudowire, use the neighbor command in interface configuration mode. To remove the peer IP address and VC ID value of an L2VPN pseudowire, use the no form of this command.

neighbor peer-address vcid-value

no neighbor

Syntax Description

peer-address

IP address of the provider edge (PE) peer.

vcid-value

VC ID value. The range is from 1 to 4294967295.

Command Default

Peer address and VC ID value of a pseudowire are not specified.

Command Modes

Interface configuration (config-if)

Command History

Release Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

You must configure the neighbor command for the pseudowire to be functional.

Examples

The following example shows how to specify a peer IP address of 10.1.2.3 and a VC ID value of 100:

Device> enable
Device# configure terminal
Device(config)# interface pseudowire 100
Device(config-if)# neighbor 10.1.2.3 100

tunnel destination

To specify the destination for a tunnel interface, use the tunnel destination command in interface configuration mode. To remove the destination, use the no form of this command.

tunnel destination {host-name ip-address | ipv6-address | dynamic}

no tunnel destination

Syntax Description

host-name

Name of the host destination.

ip-address

IP address of the host destination expressed in dotted decimal notation.

ipv6-address

IPv6 address of the host destination expressed in IPv6 address format.

dynamic

Applies the tunnel destination address dynamically to the tunnel interface.

Command Default

No tunnel interface destination is specified.

Command History

Release Modification
Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

You cannot configure two tunnels to use the same encapsulation mode with exactly the same source and destination addresses. The workaround is to create a loopback interface and configure the packet source off of the loopback interface.

Examples

The following example shows how to configure the logical Layer 3 GRE tunnel interface tunnel 2 in a global or non-VRF environment:

Device> enable
Device# configure terminal
Device(config)# interface tunnel 2
Device(config-if)# ip address 100.1.1.1 255.255.255.0
Device(config-if)# tunnel source 10.10.10.1 
Device(config-if)# tunnel destination 10.10.10.2 
Device(config-if)# tunnel mode gre ip
Device(config-if)# end

The following example shows how to configure the logical Layer 3 GRE tunnel interface tunnel 2 in a VRF environment. Use the vrf definition vrf-name and the vrf forwarding vrf-name commands to configure and apply VRF.

ip pim sparse-mode

To configure a multiaccess WAN interface to be in sparse mode, use the ip pim sparse-mode command in interface configuration mode. To disable this function, use the no form of this command.

ip pim sparse-mode

no ip pim sparse-mode

Syntax Description

This command has no arguments or keywords.

Command Default

The command is disabled.

Command Modes

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

When this command is configured on all interfaces, any existing groups running in sparse mode will continue to operate in sparse mode but will use an RP address set to 0.0.0.0. Multicast entries with an RP address set to 0.0.0.0 will exhibit the following behavior:

  • Existing (S, G) states will be maintained.

  • No PIM Join or Prune messages for (*, G) or (S, G, RPbit) are sent.

  • Received (*, G) or (S, G, RPbit) Joins or Prune messages are ignored.

  • No registers are sent and traffic at the first hop is dropped.

  • Received registers are answered with register stop.

  • Asserts are unchanged.

  • The (*, G) outgoing interface list (olist) is maintained only for the Internet Group Management Protocol (IGMP) state.

  • Multicast Source Discovery Protocol (MSDP) source active (SA) messages for RP 0.0.0.0 groups are still accepted and forwarded.

Examples

The following example configures an interface to be in sparse mode:


Device(config-if)# ip pim sparse-mode

ip pim nbma-mode

To configure a multiaccess WAN interface to be in nonbroadcast multiaccess (NBMA) mode, use the ip pim nbma-mode command in interface configuration mode. To disable this function, use the no form of this command.

ip pim nbma-mode

no ip pim nbma-mode

Syntax Description

This command has no arguments or keywords.

Command Default

The command is disabled.

Command Modes

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

Use this command on Frame Relay, Switched Multimegabit Data Service (SMDS), or ATM only, especially when these media do not have native multicast available. Do not use this command on multicast-capable LANs such as Ethernet or FDDI.

When this command is configured, each Protocol Independent Multicast (PIM) join message is tracked in the outgoing interface list of a multicast routing table entry. Therefore, only PIM WAN neighbors that have joined for the group will get packets sent as data-link unicasts. This command should only be used when the ip pim sparse-mode command is configured on the interface. This command is not recommended for LANs that have natural multicast capabilities.

Examples

The following example configures an interface to be in NBMA mode:


Device(config-if)# ip pim nbma-mode

mdt log-reuse

To enable the recording of data multicast distribution tree (MDT) reuse, use the mdt log-reuse command in VRF configuration or in VRF address family configuration mode. To disable this function, use the no form of this command.

mdt log-reuse

no mdt log-reuse

Syntax Description

This command has no arguments or keywords.

Command Default

The command is disabled.

Usage Guidelines

The mdt log-reuse command generates a syslog message whenever a data MDT is reused.

You can access the mdt log-reuse command by using the ip vrf global configuration command. You can also access the mdt log-reuse command by using the vrf definition global configuration command followed by the address-family ipv4 VRF configuration command.

Examples

The following example shows how to enable MDT log reuse:


mdt log-reuse

mdt default

To configure a default multicast distribution tree (MDT) group for a Virtual Private Network (VPN) routing and forwarding (VRF) instance, use the mdt default command in VRF configuration or VRF address family configuration mode. To disable this function, use the no form of this command.

mdt default group-address

no mdt default group-address

Syntax Description

group-address

IP address of the default MDT group. This address serves as an identifier for the community in that provider edge (PE) devices configured with the same group address become members of the group, allowing them to receive packets sent by each other.

Command Default

The command is disabled.

Command Modes

VRF address family configuration (config-vrf-af)

VRF configuration (config-vrf)

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

The default MDT group must be the same group configured on all PE devices that belong to the same VPN.

If Source Specific Multicast (SSM) is used as the protocol for the default MDT, the source IP address will be the address used to source the Border Gateway Protocol (BGP) sessions.

A tunnel interface is created as a result of this command. By default, the destination address of the tunnel header is the group-address argument.

You can access the mdt default command by using the ip vrf global configuration command. You can also access the mdt default command by using the vrf definition global configuration command followed by the address-family ipv4 VRF configuration command.

Examples

In the following example, Protocol Independent Multicast (PIM) SSM is configured in the backbone. Therefore, the default and data MDT groups are configured within the SSM range of IP addresses. Inside the VPN, PIM sparse mode (PIM-SM) is configured and only Auto-RP announcements are accepted.

mdt data

To specify a range of addresses to be used in the data multicast distribution tree (MDT) pool, use the mdt data command in VRF configuration or VRF address family configuration mode. To disable this function, use the no form of this command.

mdt data threshold kb/s

no mdt data threshold kb/s

Syntax Description

threshold kb/s

(Optional) Defines the bandwidth threshold value in kilobits per second (kb/s). The range is from 1 to 4294967.

Command Default

A data MDT pool is not configured.

Command Modes

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

A data MDT can include a maximum of 256 multicast groups per MVPN. Multicast groups used to create the data MDT are dynamically chosen from a pool of configured IP addresses.

Use the mdt data command to specify a range of addresses to be used in the data MDT pool. The threshold is specified in kb/s. Using the optional list keyword and access-list argument, you can define the (S, G) MVPN entries to be used in a data MDT pool, which would further limit the creation of a data MDT pool to the particular (S, G) MVPN entries defined in the access list specified for the access-list argument.

You can access the mdt data command by using the ip vrf global configuration command. You can also access the mdt data command by using the vrf definition global configuration command followed by the address-family ipv4 VRF configuration command.

Examples

The following example shows how to configure the range of group addresses for the MDT data pool. A threshold of 500 kb/s has been set, which means that if a multicast stream exceeds 1 kb/s, then a data MDT is created.


ip vrf vrf1

ip ospf network

To configure the Open Shortest Path First (OSPF) network type to a type other than the default for a given medium, use the ip ospf network command in interface configuration mode. To return to the default value, use the no form of this command.

ip ospf network {broadcast | non-broadcast | {point-to-multipoint [non-broadcast] | point-to-point}}

no ip ospf network

Syntax Description

broadcast

Sets the network type to broadcast.

non-broadcast

Sets the network type to nonbroadcast multiaccess (NBMA).

point-to-multipoint non-broadcast

Sets the network type to point-to-multipoint. The optional non-broadcast keyword sets the point-to-multipoint network to be nonbroadcast. If you use the non-broadcast keyword, the neighbor command is required.

point-to-point

Sets the network type to point-to-point.

Command Default

Depends on the network type.

Command Modes

Interface configuration (config-if)

Virtual network interface (config-if-vnet)

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

Using this feature, you can configure broadcast networks as NBMA networks when, for example, routers in your network do not support multicast addressing. You can also configure nonbroadcast multiaccess networks (such as X.25, Frame Relay, and Switched Multimegabit Data Service (SMDS)) as broadcast networks. This feature saves you from needing to configure neighbors.

Configuring NBMA networks as either broadcast or nonbroadcast assumes that there are virtual circuits from every router to every router or fully meshed networks. However, there are other configurations where this assumption is not true. For example, a partially meshed network. In these cases, you can configure the OSPF network type as a point-to-multipoint network. Routing between two routers that are not directly connected will go through the router that has virtual circuits to both routers. You need not configure neighbors when using this feature.

If this command is issued on an interface that does not allow it, this command will be ignored.

OSPF has two features related to point-to-multipoint networks. One feature applies to broadcast networks; the other feature applies to nonbroadcast networks:

  • On point-to-multipoint, broadcast networks, you can use the neighbor command, and you must specify a cost to that neighbor.

  • On point-to-multipoint, nonbroadcast networks, you must use the neighbor command to identify neighbors. Assigning a cost to a neighbor is optional.

Examples

The following example sets your OSPF network as a broadcast network:


Device(config)# interface serial 0
Device(config-if)# ip address 192.168.77.17 255.255.255.0
Device(config-if)# ip ospf network broadcast
Device(config-if)# encapsulation frame-relay

The following example illustrates a point-to-multipoint network with broadcast:


Device(config)# interface serial 0
Device(config-if)# ip address 10.0.1.1 255.255.255.0
Device(config-if)# encapsulation frame-relay
Device(config-if)# ip ospf cost 100
Device(config-if)# ip ospf network point-to-multipoint
Device(config-if)# frame-relay map ip 10.0.1.3 202 broadcast
Device(config-if)# frame-relay map ip 10.0.1.4 203 broadcast
Device(config-if)# frame-relay map ip 10.0.1.5 204 broadcast
Device(config-if)# frame-relay local-dlci 200
!
Device(config-if)# router ospf 1
Device(config-if)# network 10.0.1.0 0.0.0.255 area 0

Device(config-if)# neighbor 10.0.1.4 cost 10

ip multicast mrinfo-filter

To filter multicast router information (mrinfo) request packets, use the ip multicast mrinfo-filter command in global configuration mode. To remove the filter on mrinfo requests, use the no form of this command.

ip multicast [vrf vrf-name] mrinfo-filter access-list

no ip multicast [vrf vrf-name] mrinfo-filter

Syntax Description

vrf

(Optional) Supports the multicast VPN routing and forwarding (VRF) instance.

vrf-name

(Optional) Name assigned to the VRF.

access-list

IP standard numbered or named access list that determines which networks or hosts can query the local multicast device with the mrinfo command.

Usage Guidelines

The ip multicast mrinfo-filter command filters the mrinfo request packets from all of the sources denied by the specified access list. That is, if the access list denies a source, that source's mrinfo requests are filtered. mrinfo requests from any sources permitted by the ACL are allowed to proceed.

Examples

The following example shows how to filter mrinfo request packets from all hosts on network 192.168.1.1 while allowing requests from any other hosts:

ip multicast mrinfo-filter 51
access-list 51 deny 192.168.1.1 
access list 51 permit any

ip multicast-routing

To enable IP multicast routing, use the ip multicast-routing command in global configuration mode. To disable IP multicast routing, use the no form of this command.

ip multicast-routing [vrf vrf-name]

no ip multicast-routing [vrf vrf-name]

Syntax Description

vrf vrf-name

(Optional) Enables IP multicast routing for the Multicast VPN routing and forwarding (MVRF) instance specified for the vrf-name argument.

Command Default

IP multicast routing is disabled.

Command Modes

Global configuration (config).

Command History

Release

Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

When IP multicast routing is disabled, the Cisco IOS software does not forward any multicast packets.


Note


For IP multicast, after enabling IP multicast routing, PIM must be configured on all interfaces. Disabling IP multicast routing does not remove PIM; PIM still must be explicitly removed from the interface configurations.


Examples

The following example shows how to enable IP multicast routing:


Device(config)# ip multicast-routing 

The following example shows how to enable IP multicast routing on a specific VRF:


Device(config)# ip multicast-routing vrf vrf1

The following example shows how to disable IP multicast routing:


Device(config)# no ip multicast-routing

show mpls label range

Usage Guidelines

You can use the mpls label range command to configure a range for local labels that is different from the default range. The show mpls label range command displays both the label range currently in use and the label range that will be in use following the next switch reload.

Examples

In the following example, the use of the show mpls label range command is shown before and after the mpls label range command is used to configure a label range that does not overlap the starting label range:


Device# show mpls label range 
Downstream label pool: Min/Max label: 16/100
Device# configure terminal
Device(config)# mpls label range 101 4000
Device(config)# exit
Device# show mpls label range
Downstream label pool: Min/Max label: 101/4000

mpls static binding ipv4

To bind a prefix to a local or remote label, use the mpls static binding ipv4 command in global configuration mode. To remove the binding between the prefix and label, use the no form of this command.

mpls static binding ipv4 prefix mask {label | input label | output nexthop {explicit-null | implicit-null | label}}

no mpls static binding ipv4 prefix mask {label | input label | output nexthop {explicit-null | implicit-null | label}}

prefix mask

Specifies the prefix and mask to bind to a label. (When you do not use the input or output keyword, the specified label is an incoming label.)

Note

 

Without the arguments, the no form of the command removes all static bindings.

label

Binds a prefix or a mask to a local (incoming) label. (When you do not use the input or output keyword, the specified label is an incoming label.)

input label

Binds the specified label to the prefix and mask as a local (incoming) label.

output nexthop explicit-null

Binds the Internet Engineering Task Force (IETF) Multiprotocol Label Switching (MPLS) IPv4 explicit null label (0) as a remote (outgoing) label.

output nexthop implicit-null

Binds the IETF MPLS implicit null label (3) as a remote (outgoing) label.

output nexthop label

Binds the specified label to the prefix/mask as a remote (outgoing) label.

Command Default

Prefixes are not bound to local or remote labels.

Command Modes


Global configuration (config)

Release Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

The mpls static binding ipv4 command pushes bindings into Label Distribution Protocol (LDP). LDP then needs to match the binding with a route in the Routing Information Base (RIB) or Forwarding Information Base (FIB) before installing forwarding information.

The mpls static binding ipv4 command installs the specified bindings into the LDP Label Information Base (LIB). LDP will install the binding labels for forwarding use if or when the binding prefix or mask matches a known route.

Static label bindings are not supported for local prefixes, which are connected networks, summarized routes, default routes, and supernets. These prefixes use implicit-null or explicit-null as the local label.

If you do not specify the input or the output keyword, input (local label) is assumed.

For the no form of the command:

  • If you specify the command name without any keywords or arguments, all static bindings are removed.

  • Specifying the prefix and mask but no label parameters removes all static bindings for that prefix or mask.

Examples

In the following example, the mpls static binding ipv4 command configures a static prefix and label binding before the label range is reconfigured to define a range for static assignment. The output of the command indicates that the binding has been accepted, but cannot be used for MPLS forwarding until you configure a range of labels for static assignment that includes that label.


Device# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
Router(config)# mpls static binding ipv4 10.0.0.0 255.0.0.0 55
 % Specified label 55 for 10.0.0.0/8 out of configured
 % range for static labels.  Cannot be used for forwarding until 
 % range is extended.
Router(config)# end

The following mpls static binding ipv4 commands configure input and output labels for several prefixes:


Device(config)# mpls static binding ipv4 10.0.0.0 255.0.0.0 55
Device(config)# mpls static binding ipv4 10.0.0.0 255.0.0.0 output 10.0.0.66 2607
Device(config)# mpls static binding ipv4 10.66.0.0 255.255.0.0 input 17
Device(config)# mpls static binding ipv4 10.66.0.0 255.255.0.0 output 10.13.0.8 explicit-null
Device(config)# end

The following show mpls static binding ipv4 command displays the configured bindings:


Device# show mpls static binding ipv4
 
10.0.0.0/8: Incoming label: 55 
  Outgoing labels:
    10.0.0.66   2607

[H]     Local label is being held down temporarily.

The table below describes the Local Label fields relating to the Cisco IOS Software Modularity: MPLS Layer 3 VPNs feature.

Table 7. show mpls forwarding-table Field Descriptions

Field

Description

Local Label

Label assigned by this device.

  • [H]--Local labels are in holddown, which means that the application that requested the labels no longer needs them and stops advertising them to its labeling peers.

The label’s forwarding-table entry is deleted after a short, application-specific time.

If any application starts advertising a held-down label to its labeling peers, the label could come out of holddown.

Note

 

[H] is not shown if labels are held down globally.

A label enters global holddown after a stateful switchover or a restart of certain processes in a Cisco IOS modularity environment.

  • [T]--The label is forwarded through an LSP tunnel.

Note

 

Although [T] is still a property of the outgoing interface, it is shown in the Local Label column.

  • [HT]--Both conditions apply.

Examples

The following is sample output from the show mpls forwarding-table interface command. In this example, the pseudowire identifier (that is, 4096) is displayed in the Prefix or Tunnel Id column. The show mpls l2transport vc detail command can be used to obtain more information about the specific pseudowire displayed.

xconnect

To bind an attachment circuit to a pseudowire, and to configure an Any Transport over MPLS (AToM) static pseudowire, use the xconnect command in interface configuration mode. To restore the default values, use the no form of this command.

xconnect peer-ip-address vc-id encapsulation mpls [pw-type]

no xconnect peer-ip-address vc-id encapsulation mpls [pw-type]

Syntax Description

peer-ip-address

IP address of the remote provider edge (PE) peer. The remote router ID can be any IP address, as long as it is reachable.

vc-id

The 32-bit identifier of the virtual circuit (VC) between PE devices.

encapsulation mpls

Specifies Multiprotocol Label Switching (MPLS) as the tunneling method.

pw-type

(Optional) Pseudowire type. You can specify one of the following types:

  • 4: Specifies Ethernet VLAN.

  • 5: Specifies Ethernet port.

Command Default

The attachment circuit is not bound to the pseudowire.

Command Modes

Interface configuration (config-if)

Command History

Release Modification

Cisco IOS XE Gibraltar 16.11.1

This command was introduced.

Usage Guidelines

The use of the xconnect command and the interface configuration mode bridge-group command is not supported on the same physical interface.

The combination of the peer-ip-address and vcid arguments must be unique on the device. Each Xconnect configuration must have a unique combination of peer-ip-address and vcid configuration.

The same vcid value that identifies the attachment circuit must be configured using the xconnect command on the local and remote PE device. The VC ID creates the binding between a pseudowire and an attachment circuit.

Examples

The following example shows how to enter Xconnect configuration mode and bind the attachment circuit to a pseudowire VC:

Device# configure terminal
Device(config)# interface TenGigabitEthernet1/0/36
Device(config-if)# no ip address
Device(config-if)# xconnect 10.1.10.1 962 encapsulation mpls
