Configuring a BGP peer group
In a large-scale network, grouping peers that use the same route selection policy simplifies overall
configuration. When you modify the policy of the group, the modification applies to all peers in the
group. However, if a peer group already contains peers, you cannot remove or change its AS number.
A peer group is an IBGP peer group if peers in it belong to the local AS, and is an EBGP peer group if
peers in it belong to different ASs.
1. Configuring an IBGP peer group
After you create an IBGP peer group and then add a peer into it, the system creates the peer in
BGP view and specifies the local AS number for the peer.
