Step 1 |
enable
Example:
|
Enables
privileged EXEC mode.
|
Step 2 |
configure
terminal
Example:
Device# configure terminal
|
Enters global
configuration mode.
|
Step 3 |
vrf
definition
vrf-name
Example:
Device(config)# vrf definition v1

Configure a
virtual routing and forwarding (VRF) routing table instance and enters VRF
configuration mode
|
Step 4 |
address-family ipv6 [unicast]
Example:
Device(config-vrf)# address-family ipv6
|
Specifies the
IPv6 address family, and enters address family configuration mode.
Note
|
The
unicast keyword specifies the unicast IPv6 unicast
address family. By default, the device is placed in configuration mode for the
unicast IPv6 address family if the unicast keyword is not specified with the
address-family ipv6 command.
|
|
Step 5 |
exit
Example:
Device(config-vrf-af)# exit
|
Exits the
address family configuration mode and enters VRF configuration mode.
|
Step 6 |
exit
Example:
|
Exits the VRF
configuration mode and enters global configuration mode.
|
Step 7 |
interface
type
number
Example:
Device(config)# interface FastEthernet 0/2
|
Configures
an interface type and enters interface configuration mode.
|
Step 8 |
vrf
forwarding
vrf-name
Example:
Device(config-if)# vrf forwarding v1
| (Optional)
Associates a
Virtual Routing and Forwarding (VRF) or a virtual network with an interface or
subinterface
|
Step 9 |
ipv6
address
ipv6-prefix/prefix-length
Example:
Device(config-if)# ipv6 address 2001:DB8::/32
|
Sets an
IPv6 address for an interface.
|
Step 10 |
ipv6
router
isis
process-tag
Example:
Device(config-if)# ipv6 router isis v1a
|
Configures
an IS-IS routing process for IPv6 on an interface and attaches a tag to the
routing process.
Note
|
The
configuration of the interface-mode
ipv6
router
isis command will overwrite the prior
configuration on that interface, but only if the new configuration is
attempting to change the interface ownership to a different instance that is in
the same VRF as the currently configured owner instance. The configuration will
be rejected if the attempted change is between two instances that are
associated with different VRFs.
|
|
Step 11 |
exit
Example:
|
Exits the
interface configuration mode and enters global configuration mode.
|
Step 12 | Repeat Step
7 to Step 11 to configure IS-IS routing process and VRFs for IPv6 on different
interfaces.
Example:
|
--
|
Step 13 |
router
isis
process-tag
Example:
Device(config)# router isis v1a
|
Enables
IS-IS for the specified IS-IS routing process, and enters router configuration
mode.
|
Step 14 |
vrf
vrf-name
Example:
Device(config-if)# vrf v1
| (Optional)
Associates a
Virtual Routing and Forwarding (VRF) instance or a virtual network with an
interface or subinterface
|
Step 15 |
net
network-entity-title
Example:
Device(config-router)# net 49.000b.0000.0001.0002.00
|
Configures
IS-IS network entity title (NET) for a CLNS routing process.
|
Step 16 |
is-type
[level-1 |
level-1-2 |
level-2-only]
Example:
Device(config-router)# is-type level-1
|
Configures
the routing level for an instance of the IS-IS routing process.
|
Step 17 |
log-adjacency-changes
Example:
Device(config-router)# log-adjacency-changes
|
Configure
the device to send a syslog message when an Open Shortest Path First (OSPF)
neighbor goes up or down.
|
Step 18 |
address-family ipv6 [unicast]
Example:
Device(config-router)# address-family ipv6
|
Specifies
the IPv6 address family, and enters address family configuration mode.
Note
|
The
unicast keyword specifies the unicast IPv6 unicast
address family. By default, the device is placed in configuration mode for the
unicast IPv6 address family if the unicast keyword is not specified with the
address-family ipv6 command.
|
|
Step 19 |
redistribute
source-protocol [process-id] [route-map
map-tag]
Example:
Device(config-router-af)# redistribute isis v1a route-map abc
|
Specifies
the route map that should be checked to filter the importation of routes from
this source routing protocol to the current routing protocol.
|
Step 20 |
redistribute isis
[process-id] {level-1 |
level-2}
into {level-1 |
level-2}
distribute-list
list-name
Example:
Device(config-router-af)# redistribute isis level-1 into level-2 distribute-list xyz
|
Redistributes IPv6 routes from one IS-IS level into another IS-IS level. By
default, the routes learned by Level 1 instances are redistributed by the Level
2 instance.
|
Step 21 |
exit
Example:
Device(config-router-af)# exit
|
Exits the
address family configuration mode and enters router configuration mode.
|
Step 22 |
exit
Example:
Device(config-router)# exit
|
Exits the
router configuration mode and enters global configuration mode.
|
Step 23 |
route-map
map-tag [permit |
deny] [sequence-number]
Example:
Device(config)# route-map abc permit 10
|
Defines the
conditions for redistributing routes from one routing protocol into another or
from one IS-IS level to another and enters route-map configuration mode.
|
Step 24 |
match
route-type {level-1 |
level-2}
Example:
Device(config-route-map)# match route-type level-1
|
Defines the
route-type match criterion.
|
Step 25 |
set
metric
metric-value
Example:
Device(config-route-map)# set metric 56
|
Configures
the metric value used to redistribute routes.
|
Step 26 |
set
level {level-1 |
level-2 |
level-1-2}
Example:
Device(config-route-map)# set level level-2
|
Specifies
the routing level of routes to be advertised into a specified area of the
routing domain.
|
Step 27 |
end
Example:
Device(config-route-map)# end
|
Exits the
route-map configuration mode and enters privileged EXEC mode.
