BGP—peer group 实验整理—威哥.docx

怕吃苦，吃苦一辈子；不怕苦，吃苦半辈子！BGP Peer GroupPeer Group 就相当于是一个容器，这个容器拥有着 BGP 参数和策略，只要将 BGP 邻居放入这个容器中，那么该邻居即可获得容器的所有参数和策略，从而大大简化为每个邻居重复配置相同参数和策略。 Peer Group 唯一的限制就是，同一个 Peer Group 中的所有邻居，必须全部为iBGP 邻居，或者全部为 eBGP 邻居.R5：router bgp 1 no synchronization bgp router-id 5.5.5.5 bgp log-neighbor-changes neighbor as1 peer-group neighbor as1 remote-as 1 neighbor as1 update-source Loopback0 neighbor as45 peer-group neighbor as45 ebgp-multihop 255 neighbor as45 update-source Loopback0 neighbor 1.1.1.1 peer-group as1 neighbor 2.2.2.2 peer-group as1 neighbor 3.3.3.3 remote-as 4 neighbor 3.3.3.3 peer-group as45 no auto-summaryR1(config)#do sh run | b r brouter bgp 1 no synchronization bgp router-id 1.1.1.1 bgp log-neighbor-changes network 11.1.1.0 mask 255.255.255.0 neighbor 5.5.5.5 remote-as 1 neighbor 5.5.5.5 update-source Loopback0 no auto-summaryR2(config)#do sh run | b r brouter bgp 1 no synchronization bgp router-id 2.2.2.2 bgp log-neighbor-changes neighbor 5.5.5.5 remote-as 1 neighbor 5.5.5.5 update-source Loopback0 no auto-summaryR3(config)#do sh run | b r brouter bgp 4 no synchronization bgp router-id 3.3.3.3 bgp log-neighbor-changes network 33.3.3.0 mask 255.255.255.0 neighbor 5.5.5.5 remote-as 1 neighbor 5.5.5.5 ebgp-multihop 255 neighbor 5.5.5.5 update-source Loopback0 no auto-summary测试：R5(config-router
