Chapter 38 Configuring IP Unicast Routing

Configuring BGP

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

Figure 38-5

.

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

BGP version 4, remote router ID 175.220.212.1

BGP state = established, table version = 3, up for 0:10:59

Last read 0:00:29, hold time is 180, keepalive interval is 60 seconds

Minimum time between advertisement runs is 30 seconds

Received 2828 messages, 0 notifications, 0 in queue

Step 12

show ip bgp network network-number

or


show ip bgp neighbor

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

Step 13
