Cisco IOS XR Routing Configuration Guide
Step 4
exit
Example:
RP/0/RP0/CPU0:router(config-if)# exit
Exits interface configuration mode, and returns the router to
global configuration mode.
Step 5
router isis
instance-id
Example:
RP/0/RP0/CPU0:router(config)# router isis isp
Enables IS-IS routing for the specified routing instance, and
places the router in router configuration mode.
• You can change the level of routing to be performed by
a particular routing instance using the is-type router
configuration command.
Step 6
net
network-entity-title
Example:
RP/0/RP0/CPU0:router(config-isis)# net
47.0004.004d.0001.0001.0c11.1110.00
Configures NETs for the routing instance.
• Specify a NET for each routing instance if you are
configuring multi-instance IS-IS. You can specify a
name for a NET and for an address.
• This example configures a router with area ID
47.0004.004d.0001 and system ID 0001.0c11.1110.10.
• To specify more than one area address, specify
additional NETs. Although the area address portion of
the NET differs, the system ID portion of the NET must
match exactly for all of the configured items.
Step 7
interface
type instance
Example:
RP/0/RP0/CPU0:router(config-isis)# interface
POS 0/1/0/4
Enters interface configuration mode.
Step 8
address-family ipv4 [unicast]
Example:
RP/0/RP0/CPU0:router(config-isis-if)#
address-family ipv4 unicast
Specifies the IPv4 address family and enters interface
address family configuration mode.
• This example specifies the unicast IPv4 address family.
Step 9
exit
Example:
RP/0/RP0/CPU0:router(config-if)# exit
Exits interface configuration mode, and returns the router to
interface configuration mode.
Step 10
address-family ipv6 [unicast]
Example:
RP/0/RP0/CPU0:router(config-isis-if)#
address-family ipv6 unicast
Specifies the IPv6 address family and enters interface
address family configuration mode.
• This example specifies the unicast IPv6 address family.
