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 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
if a neighbor’s configuration is more specific than its peer group’s configuration,
the neighbor may retain its configuration after it is added to the peer group. The
neighbor’s configuration does not affect 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 configuring the
remote-as for Internal BGP (IBGP) or External BGP (EBGP).
This command automatically restarts the neighbor session for the configuration to
take effect.
