Configuring a BGP peer group
The peers in a peer group use the same route selection policy.
In a large-scale network, many peers can use the same route selection policy. You can configure a peer

also applies to the peers in the group.
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.

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.
To configure an IBGP peer group (IPv4):
