Configure Peer Groups
To configure multiple BGP neighbors at one time, create and populate a BGP peer group. Another
advantage of peer groups is that members of a peer groups inherit the configuration properties of the group
and share same update policy.
A maximum of 256 Peer Groups are allowed on the system.
You create a peer group by assigning it a name, then adding members to the peer group. Once a peer group
is created, you can configure route policies for it. Refer to Filter BGP routes for information on configuring
route policies for a peer group.
Use these commands in the following sequence starting in the CONFIGURATION ROUTER BGP mode
to create a peer group.
Note: Sample Configurations for enabling Peer Groups are found at the end of this chapter.
