Information
Configure the same password on both BGP peers or a connection does not occur.
When you configure MD5 authentication between two BGP peers, each segment of
the TCP connection between them is verified and the MD5 digest is checked on every
segment sent on the TCP connection.
Configuring a password for a neighbor will cause an existing session to be torn down
and a new one established.
