12-14
num is the AS number that internally includes multiple ASs.
2. To configure an AS to be a member of the confederation, use the bgp
confederation peers command in Router BGP Configuration mode, as shown
below:
MOT(config-bgp)#bgp confederation peers <num>
where:
num specifies the AS that is a member of the confederation.
Example 1
The commands in this example configure Router Hartford (as shown in Figure 12-5)
and specify that the Router Hartford belongs to Confederation 400. They also specify
that Router Hartford belongs to a confederation containing AS 200 and AS 300 as its
peer ASs, specify that connections with confederation peers in AS 100 and AS 200,
and specify an external peer in AS 500.
MOT(config)#router bgp 100
MOT(config-bgp)#bgp confederation identifier 400
MOT(config-bgp)#bgp confederation peers 200 300
MOT(config-bgp)#neighbor 140.100.30.1 remote-as 100
MOT(config-bgp)#neighbor 140.100.20.1 remote-as 100
MOT(config-bgp)#neighbor 139.100.30.1 remote-as 200
MOT(config-bgp)#neighbor 7.7.7.2 remote-as 500
Example 2
The commands in this example configure Router Chicago (as shown in Figure 12-5):
MOT(config)#router bgp 200
MOT(config-bgp)#bgp confederation identifier 400
MOT(config-bgp)#bgp confederation peers 100 300
MOT(config-bgp)#neighbor 140.100.40.1 remote-as 100
MOT(config-bgp)#neighbor 139.100.20.1 remote-as 200
MOT(config-bgp)#neighbor 160.21.10.1 remote-as 300
