Chapter 24 Configuring NSF with SSO MSFC Redundancy
Using the CLI to Configure NSF/SSO
Configuring BGP NSF
Note You must configure BGP graceful restart on all peer devices that participate in BGP NSF.
To configure BGP for NSF, perform this task (repeat this procedure on each of the BGP NSF peer
devices):
Verifying BGP NSF
To verify BGP NSF, you must check that the graceful restart function is configured on the SSO-enabled
networking device and on the neighbor devices. To verify, follow these steps:
Step 1 Verify that “bgp graceful-restart” appears in the BGP configuration of the SSO-enabled router by
entering the show running-config command:
Router# show running-config
.
.
.
router bgp 120
.
.
.
bgp graceful-restart
neighbor 10.2.2.2 remote-as 300
.
.
.
Step 2 Repeat step 1 on each of the BGP neighbors.
Purpose Command
Step 1
Enter global configuration mode.
Router# configure terminal
Step 2
Enable a BGP routing process, which
places the router in router configuration
mode.
Router(config)# router bgp as-number
Step 3
Enable the BGP graceful restart
capability, starting BGP NSF.
If you enter this command after the BGP
session has been established, you must
restart the session for the capability to be
exchanged with the BGP neighbor.
Use this command on the restarting
router and all of its peers.
Router(config-router)# bgp graceful-restart
