DETAILED STEPS
PurposeCommand or Action
configure
Step 1
Enables IS-IS routing for the specified routing instance, and
places the router in router configuration mode.
router isis instance-id
Example:
RP/0/RSP0/CPU0:router(config)# router isis
isp
Step 2
•
You can change the level of routing to be performed by a
particular routing instance by using the is-type router
configuration command.
(Optional) Sets the time between regeneration of LSPs that
contain different sequence numbers
lsp-refresh-interval seconds [ level { 1 | 2 }]
Example:
RP/0/RSP0/CPU0:router(config-isis)#
lsp-refresh-interval 10800
Step 3
•
The refresh interval should always be set lower than the
max-lsp-lifetime command.
