BGP4 Neighbor Configuration

The IP address of the neighbor is the primary IP address of the interface connection. For each neighbor, you can specify a set of attributes. In cases where a set of neighbors share the same set of attributes, it is a best practice to create a peer-group. For more information, see BGP4 Peer Groups.

The neighbor configuration appears in both the global and address-family modes of BGP. The neighbor parameters that are common to all of the address families are available from BGP global configuration mode. The parameters that are specific to an address family are available from BGP address-family submode.

Several neighbor configuration options are available from BGP global configuration mode.
