回答

Route1在AS 65500中

Router1(config)#interface Serial0

Router1(config-if)#ip address 192.168.55.6 255.255.255.252

Router1(config-if)#exit

Router1(config)#router bgp 65500

Router1(config-router)#network 192.168.1.0

Router1(config-router)#neighbor 192.168.55.5 remote-as 65501

Router1(config-router)#no synchronization

Router1(config-router)#exit

Router1(config)#end

Router1#

Router2在AS 65501中

Router2#configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

Router2(config)#interface Serial0

Router2(config-if)#ip address 192.168.55.5 255.255.255.252

Router2(config-if)#exit

Router2(config)#router bgp 65501

Router2(config-router)#network 172.25.17.0 mask 255.255.255.0

Router2(config-router)#neighbor 192.168.55.6 remote-as 65500

Router2(config-router)#no synchronization

Router2(config-router)#exit

Router2(config)#end

Router2#
