Enabling High Availability Features

 

Command

Purpose

 

 

 

Step 3

Router(config-router)# nsf [cisco ietf]

Enables NSF operation for IS-IS.

 

 

Use the ietf keyword to enable IS-IS in homogeneous

 

 

network where adjacencies with networking devices

 

 

supporting IETF draft-based restartability is guaranteed.

 

 

Use 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

(Optional) Specifies the minimum time between NSF restart

 

[minutes]

attempts. The default time between consecutive NSF restart

 

 

attempts is 5 minutes.

 

 

 

Step 5

Router(config-router)# nsf t3 {manual

(Optional) Specifies the time IS-IS will wait for the IS-IS

 

[seconds] adjacency}

database to synchronize before generating overloaded

 

 

link-state information for itself and flooding that information

 

 

out to its neighbors.

 

 

The t3 keyword applies only if you selected ietf operation.

 

 

Specifying adjacency means that the restarting router

 

 

obtains its wait time from neighboring devices.

 

 

 

Step 6

Router(config-router)# nsf interface

(Optional) Specifies how long an IS-IS NSF restart will wait

 

wait seconds

for all interfaces with IS-IS adjacencies to come up before

 

 

completing the restart. The default is 10 seconds.

 

 

 

Verifying CEF NSF

 

 

 

To verify that CEF is NSF-capable, use the show cef state command:

 

 

 

Router# show cef state

 

 

 

CEF Status [RP]

 

 

 

CEF enabled/running

 

 

 

dCEF enabled/running

NVGEN CEF state: no

 

 

 

fastsend() used: no

 

 

 

ACL logging at irq: no

 

 

 

Per-packet loadbalancing: no

 

 

 

Allow CEF re-enable: no

 

 

 

MAC accounting on RP: no

 

 

 

Background ADJ updater: no

 

 

 

Force loadinfo structures: no

 

 

 

CEF NSF capable: yes

 

 

 

IPC delayed func on SSO: no

 

 

 

FIB auto repair supported: yes

 

 

 

HW forwarding on this platform: no

 

 

 

HW forwarding in this CEF instance:no

 

 

 

LCs not running at init time:no

 

 

 

IP CEF accounting supported:yes
