Usage
Information
You can assign up to 64 peers to one peer group.
When you add a peer to a peer group, it inherits all the peer group’s configured
parameters. A peer cannot become part of a peer group if any of the following
commands are configured on the peer:
• neighbor advertisement-interval
• neighbor distribute-list
• neighbor route-map
• neighbor route-reflector-client
• neighbor send-community
A neighbor may keep its configuration after it was added to a peer group if the
neighbor’s configuration is more specific than the peer group’s, and the neighbor’s
configuration does not affect outgoing updates.
A peer group must exist before you add a peer to it. If the peer group is disabled
(shutdown), the peers within the group are also disabled (shutdown).
