DETAILED STEPS
Command or Action
Step 1
configure
Step 2
router isis instance-id
Example:
RP/0/RSP0/CPU0:router(config)# router isis
isp
Step 3 lsp-refresh-interval seconds [ level { 1 | 2 }]
Example:
RP/0/RSP0/CPU0:router(config-isis)#
lsp-refresh-interval 10800
Purpose
Enables IS-IS routing for the specified routing instance, and
places the router in router configuration mode.
(Optional) Sets the time between regeneration of LSPs that
contain different sequence numbers

Controlling LSP Flooding for IS-IS
[ level { 1 | 2 }]
• You can change the level of routing to be performed by a
particular routing instance by using the is-type router
configuration command.
• The refresh interval should always be set lower than the
max-lsp-lifetime command.
