DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enters IS-IS configuration submode.
router isis instance-id
Example:
RP/0/RSP0/CPU0:router(config)# router isis purple
Step 2
Associates an IS-IS topology ID with the named
topology.
address-family { ipv4 | ipv6 } multicast topology
topo-name
Example:
RP/0/RSP0/CPU0:router(config-isis)# address-family
ipv4 multicast topology green
Step 3
Configures the numeric multitopologyID in IS-IS
that identifies the topology. Range is 6 to 4095.
topology-id multitoplogy-id
Example:
RP/0/RSP0/CPU0:router(config-isis-af)# toplogy-id 122
