Verifying BGP NSF

To verify NSF for BGP, you must check that the graceful restart function is configured on the

SSO-enabled networking device and on the neighbor devices. Perform the following steps:

Step 1 Verify that “bgp graceful-restart” appears in the BGP configuration of the SSO-enabled router by entering the show running-configcommand:

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.

Step 3 On the SSO device and the neighbor device, verify that the graceful restart function is shown as both advertised and received, and confirm the address families that have the graceful restart capability. If no address families are listed, then BGP NSF also will not occur:

Router# show ip bgp neighbors x.x.x.x

BGP neighbor is 192.168.2.2, remote AS YY, external link

BGP version 4, remote router ID 192.168.2.2

BGP state = Established, up for 00:01:18

Last read 00:00:17, hold time is 180, keepalive interval is 60 seconds
