ip-address: IP address of the peer.
cipher: Displays the configured password in cipher text mode.
simple: Displays the configured password in simple text mode.
password: Password in character string form with 1 to 16 characters when parameter
simple is configured in the command or in the event of inputting the password in
simple text mode but parameter cipher is configured in the command; with 24

Description
Use the peer password command to configure MD5 authentication for BGP during
TCP connection setup.
Use the undo peer password command to cancel the configuration.
By default, BGP does not perform MD5 authentication when TCP connection is set
up.
Once MD5 authentication is enabled, both parties involved in the authentication must
be configured with identical authentication modes and passwords. Otherwise, TCP
connection will not be set up because of the failed authentication.
This command is used to configure MD5 authentication for the specific peer only
when the peer group to which the peer belongs is not configured with MD5
authentication. Otherwise, the peer should be consistent with the peer group.
Example
# Adopt MD5 authentication on the TCP connection set up between the local router at
10.1.100.1 and the peer router at 10.1.100.2.
