Usage Information
You can assign up to 256 peers to one peer group.
When you add a peer to a peer group, it inherits all the peer group’s congured parameters. A peer cannot become
part of a peer group if any of the following commands are congured on the peer:
• neighbor advertisement-interval
• neighbor distribute-list
• neighbor route-map
• neighbor route-reector-client
if a neighbor’s conguration is more specic than its peer group’s conguration, the neighbor may retain its
conguration after it is added to the peer group. The neighbor’s conguration does not aect outgoing updates.
A peer group must exist (be enabled) before you add a peer to it. If the peer group is disabled (shutdown), the
peers within that group are also disabled (shutdown).
In BGP, you cannot associate a peer to a peer-group without conguring the remote-as for Internal BGP (IBGP) or
External BGP (EBGP).
This command automatically restarts the neighbor session for the conguration to take eect.
