Configuring BGP NSF
Note
You must configure BGP graceful restart on all peer devices participating 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
.
.
.
Command
Purpose
Step 1
Router#
configure terminal
Enters global configuration mode.
Step 2
Router(config)#
router bgp
as-number
Enables a BGP routing process, which places the
router in router configuration mode.
Step 3
Router(config-router)#
bgp graceful-restart
Enables 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.
