neighbor peer-group — router, BGP
Assigns a neighbor to a peer group
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.
In this example, we create a peer group called
group1 and place all our neighbors into this peer group (184.108.40.206, 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.
