Usage
Information
You must configure your system to accept 4-Byte formats before entering a 4-Byte AS Number. If the
number parameter is the same as the AS number used in the router bgp command, the remote AS entry
in the neighbor is considered an internal BGP peer entry.
This command creates a peer and the newly created peer is disabled (shutdown).
