Configuring IS-IS NSF
To configure IS-IS NSF, perform this task:
Command Purpose
Step 1
Router# configure terminal
Enters global configuration mode.
Step 2
Router(config)# router isis [
tag
]
Enables an IS-IS routing process, which places the
router in router configuration mode.
Step 3
Router(config-router)# nsf [cisco | ietf]
Enables NSF operation for IS-IS.
Enter the ietf keyword to enable IS-IS in a
homogeneous network where adjacencies with
networking devices supporting IETF draft-based
restartability is guaranteed.
Enter the cisco keyword to run IS-IS in
heterogeneous networks that might not have
adjacencies with NSF-aware networking devices.
Step 4
Router(config-router)# nsf interval [
minutes
]
(Optional) Specifies the minimum time between
NSF restart attempts. The default time between
consecutive NSF restart attempts is 5 minutes.
