Cisco ASR 9000 Series Routing Configuration Guide

DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enables IS-IS routing for the specified routing process,
and places the router in router configuration mode. In
this example, the IS-IS instance is called isp.
router isis instance-id
Example:
RP/0/RSP0/CPU0:router(config)# router isis isp
Step 2
Specifies the IPv4 or IPv6 address family, and enters
router address family configuration mode.
address-family { ipv4 | ipv6 } [ unicast ]
Example:
RP/0/RSP0/CPU0:router(config-isis)# address-family
ipv4 unicast
Step 3
Configures a router to generate and accept only wide
link metrics in the Level 1 area.
metric-style wide [ transition ] [ level { 1 | 2 }]
Example:
RP/0/RSP0/CPU0:router(config-isis-af)#
metric-style wide level 1
Step 4
Exits router address family configuration mode, and
returns the router to router configuration mode.
exit
Example:
RP/0/RSP0/CPU0:router(config-isis-af)# exit
Step 5
Enters interface configuration mode.
interface type number
Example:
RP/0/RSP0/CPU0:router(config-isis)# interface
GigabitEthernet 0/1/0/3
Step 6
Specifies the IPv4 or IPv6 address family, and enters
address family configuration mode.
address-family { ipv4 | ipv6 } [ unicast ]
Example:
RP/0/RSP0/CPU0:router(config-isis-if)#
address-family ipv4 unicast
Step 7
Sets the value of the tag to associate with the advertised
connected route.
tag tag
Example:
RP/0/RSP0/CPU0:router(config-isis-if-af)# tag 3
