DETAILED STEPS
Step 1
configure
Step 2 router isis instance-id
Example:
RP/0/RP0/CPU0:router(config)# router isis isp
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.
Step 3
address-family { ipv4 | ipv6 } [ unicast ]
Example:
RP/0/RP0/CPU0:router(config-isis)# address-family ipv4 unicast
Specifies the IPv4 or IPv6 address family, and enters router address family configuration mode.
Step 4
metric-style wide [ transition ] [ level { 1 | 2 }]
Example:
RP/0/RP0/CPU0:router(config-isis-af)# metric-style wide level 1
Configures a router to generate and accept only wide link metrics in the Level 1 area.
Step 5
exit
Example:
RP/0/RP0/CPU0:router(config-isis-af)# exit
Exits router address family configuration mode, and returns the router to router configuration mode.
Step 6
interface type number
Example:
RP/0/RP0/CPU0:router(config-isis)# interface HundredGigE 0/1/0/3
configure
router isis instance-id
address-family { ipv4 | ipv6 } [ unicast ]
metric-style wide [ transition ] [ level { 1 | 2 }]
exit
interface type number
address-family { ipv4 | ipv6 } [ unicast ]
