Explanation

BGP Authentication BGP supports MD5 authentication between neighbors, using a shared password. It is configured under BGP router configuration mode with the command neighbor {ip-address | peer-group- name} password password. When authentication is configured, BGP authenticates every TCP segment from its peer and checks the source of each routing update. Most ISPs require authentication for their EBGP peers.
