BGP—peer group 實驗整理—威哥.docx

怕吃苦，吃苦一輩子；不怕苦，吃苦半輩子！BGP Peer GroupPeer Group 就相當于是一個容器，這個容器擁有著 BGP 參數(shù)和策略，只要將 BGP 鄰居放入這個容器中，那么該鄰居即可獲得容器的所有參數(shù)和策略，從而大大簡化為每個鄰居重復配置相同參數(shù)和策略。 Peer Group 唯一的限制就是，同一個 Peer Group 中的所有鄰居，必須全部為iBGP 鄰居，或者全部為 eBGP 鄰居.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測試：R5(config-router
