parameter simple is configured in the command or in the event of inputting the

Description
Using the peer password command, you can configure MD5 authentication for
BGP during TCP connection setup. Using the undo peer password command, you
can 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.
