Description
When configuring BGP, you often want to apply the same set of
configuration items to a number of BGP neighbors. Peer groups let you
simplify the router configuration by making a neighbor a peer group
member. Once you have created a peer group, all configuration items
for that group apply to all the members of the group.
address
is the IP address of the neighbor
to be added to the peer group; peer-group
is the name of the peer group.
Example
In this example, we create a peer group called
group1
and place all our neighbors into this peer
group (179.69.232.53, 54, and 55). Having created the peer group, we
can apply neighbor
filter-list
commands to the group as a whole, rather than to the individual
neighbors. We still have to configure the unique features (such as
remote AS numbers) of the neighbors individually.
