To add an internal BGP (IBGP) neighbor, configure the as-number parameter with the same BGP asnumber configured in the router bgp as-number command. Examples of Viewing and Configuring Peer Groups After you create a peer group, you can use any of the commands beginning with the keyword neighbor to configure that peer group. When you add a peer to a peer group, it inherits all the peer group's configured parameters. A neighbor cannot become part of a peer group if it has any of the following commands configured: • neighbor advertisement-interval • neighbor distribute-list out • neighbor filter-list out • neighbor next-hop-self • neighbor route-map out • neighbor route-reflector-client • neighbor send-community A neighbor may keep its configuration after it was added to a peer group if the neighbor's configuration is more specific than the peer group's and if the neighbor's configuration does not affect outgoing updates. NOTE: When you configure a new set of BGP policies for a peer group, always reset the peer group by entering the clear ip bgp peer-group peer-group-name command in EXEC Privilege mode. To view the configuration, use the show config command in CONFIGURATION ROUTER BGP mode. When you create a peer group, it is disabled (shutdown). The following example shows the creation of a peer group (zanzibar) (in bold). Dell(conf-router_bgp)#neighbor zanzibar peer-group Dell(conf-router_bgp)#show conf ! router bgp 45 bgp fast-external-fallover bgp log-neighbor-changes neighbor zanzibar peer-group neighbor zanzibar shutdown neighbor 10.1.1.1 remote-as 65535 neighbor 10.1.1.1 shutdown neighbor 10.14.8.60 remote-as 18505 neighbor 10.14.8.60 no shutdown Dell(conf-router_bgp)# To enable a peer group, use the neighbor peer-group-name no shutdown command in CONFIGURATION ROUTER BGP mode (shown in bold). Dell(conf-router_bgp)#neighbor zanzibar no shutdown Dell(conf-router_bgp)#show config ! router bgp 45 bgp fast-external-fallover bgp log-neighbor-changes neighbor zanzibar peer-group neighbor zanzibar no shutdown neighbor 10.1.1.1 remote-as 65535 206 Border Gateway Protocol IPv4 (BGPv4)
