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 are 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 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. Use the show config command in the CONFIGURATION ROUTER BGP mode to view the configuration. When you create a peer group, it is disabled (shutdown). Figure 10-19 shows the creation of a peer group (zanzibar). Figure 10-19. Command example: show config (creating peer-group) FTOS(conf-router_bgp)#neighbor zanzibar peer-group FTOS(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 FTOS(conf-router_bgp)# Configuring neighbor zanzibar Use the neighbor peer-group-name no shutdown command in the CONFIGURATION ROUTER BGP mode to enable a peer group.
