Configuring BGP
Command
Step 12
show ip bgp network network-number
or
show ip bgp neighbor
Step 13
copy running-config startup-config
Use the no router bgp autonomous-system global configuration command to remove a BGP autonomous
system. Use the no network network-number router configuration command to remove the network from
the BGP table. Use the no neighbor {ip-address | peer-group-name} remote-as number router
configuration command to remove a neighbor. Use the no neighbor {ip-address | peer-group-name}
remove-private-as router configuration command to include private autonomous-system numbers in
updates to a neighbor. Use the synchronization router configuration command to re-enable
synchronization.
These examples show how to configure BGP on the routers in
Router A:
Switch(config)# router bgp 100
Switch(config-router)# neighbor 129.213.1.1 remote-as 200
Router B:
Switch(config)# router bgp 200
Switch(config-router)# neighbor 129.213.1.2 remote-as 100
Switch(config-router)# neighbor 175.220.1.2 remote-as 200
Router C:
Switch(config)# router bgp 200
Switch(config-router)# neighbor 175.220.212.1 remote-as 200
Switch(config-router)# neighbor 192.208.10.1 remote-as 300
Router D:
Switch(config)# router bgp 300
Switch(config-router)# neighbor 192.208.10.2 remote-as 200
To verify that BGP peers are running, use the show ip bgp neighbors privileged EXEC command. This
is the output of this command on Router A:
Switch# show ip bgp neighbors
BGP neighbor is 129.213.1.1, remote AS 200, external link

Purpose
Verify the configuration.
Verify that NSF awareness (graceful restart) is enabled on the
neighbor.
If NSF awareness is enabled on the switch and the neighbor,
this message appears:
Graceful Restart Capability: advertised and received
If NSF awareness is enabled on the switch, but not on the
neighbor, this message appears:
Graceful Restart Capability: advertised
