The automatic shutdown of BGP neighbors on initial configuration feature prevents a BGP peer from attempting to establish connections with remote peers when the BGP peer is first configured. Neighbors that you add to a peer group have the shutdown flag enabled by default.
device# configure terminal
device(config)# router bgp
device(config-bgp-router)# local-as 65520
device(config-bgp-router)# no neighbor 10.1.1.1 shutdown
The following example summarizes the commands in this procedure.
device# configure terminal device(config)# router bgp device(config-bgp-router)# local-as 65520 device(config-bgp-router)# no neighbor 10.1.1.1 shutdown
