Define BGP Groups and Peers

A BGP system must know which routers are its peers (neighbors). You define the peer relationships explicitly by configuring the neighboring routers that are the peers of the local BGP system. After peer relationships have been established, the BGP peers exchange update messages to advertise network reachability information.

You arrange BGP routers into groups of peers. Different peer groups must have different group types, AS numbers, or router reflector cluster identifiers.

Each group must contain at least one peer.

To define BGP groups and peers, you can do the following:

• Define a Group with Static Peers
• Define a Group with Dynamic Peers
• Define the Group Type
• Specify the Peer's AS Number
• Define Group Properties
• Define Peer Properties
