BGP Peer Group对等体组配置.docx

BGP Peer Group对等体组配置拓扑及配置有异于上篇文章在AS 1 内部起RIP协议，使R1 R2 R3互通，然后在所有路由器上起BGP协议。对R1只起一个peer-group，把R2 R3放进这个对等体组中。又R2 R3会存在IBGP水平分割，会互相学习不到对方的环回，我们又在R1上做了路由反射器，R2 R3作为客户端。R1:interface Loopback0ip address 1.1.1.1 255.255.255.0!interface Serial0/0ip address 14.14.14.1 255.255.255.0!interface Serial0/1ip address 15.15.15.1 255.255.255.0!interface Serial0/2ip address 12.12.12.1 255.255.255.0!interface Serial0/3ip address 13.13.13.1 255.255.255.0!router ripversion 2network 1.0.0.0network 12.0.0.0network 13.0.0.0no auto-summary!router bgp 1no synchronizationbgp router-id 1.1.1.1bgp log-neighbor-changesnetwork 1.1.1.0 mask 255.255.255.0neighbor as1 peer-group /定义一个peer-group，名为as1neighbor as1 remote-as 1neighbor as1 update-source Loopback0neighbor as1 route-reflector-client /as1中的路由器都作为路由反射器客户neighbor as1 next-hop-selfneighbor 2.2.2.2 peer-group as1neighbor 3.3.3.3 peer-group as1neighbor 14.14.14.4 remote-as 4neighbor 15.15.15.5 remote-as 5no auto-summary对于其它四台路由器都是做正常的普通BGP配置：R2:interface Loopback0ip address 2.2.2.2 255.255.255.0!interface Serial0/0ip address 12.12.12.2 255.255.255.0!router ripversion 2network 2.0.0.0network 12.0.0.0no auto-summary!router bgp 1no synchronizationbgp router-id 2.2.2.2bgp log-neighbor-changesnetwork 2.2.2.0 mask 255.255.255.0neighbor 1.1.1.1 remote-as 1neighbor 1.1.1.1 update-source Loopback0no auto-summaryR3:interface Loopback0ip address 3.3.3.3 255.255.255.0!interface Serial0/0ip address 13.13.13.3 255.255.255.0!router ripversion 2network 3.0.0.0network 13.0.0.0no auto-summary!router bgp 1no synchronizationbgp router-id 3.3.3.3bgp log-neighbor-changesnetwork 3.3.3.0 mask 255.255.255.0neighbor 1.1.1.1 remote-as 1neighbor 1.1.1.1 update-source Loopback0no auto-summaryR4:interface Loopback0ip address 4.4.4.4 255.255.255.0!interface Serial0/0ip address 14.14.14.4 255.255.255.0!router bgp 4no synchronizationbgp router-id 4.4.4.4bgp log-neighbor-changesnetwork 4.4.4.0 mask 255.255.255.0neighbor 14.14.14.1 remote-as 1no auto-summaryR5:interface Loopback0ip address 5.5.5.5 255.255.255.0!interface Serial0/0ip address 15.15.15.5 255.255.255.0!router bgp 5no synchronizationbgp router-id
