Troubleshooting Tips

If a device has a password configured for an MSDP peer but the MSDP peer does not, a message such as the
following will appear on the console while the devices attempt to establish an MSDP session between them:
%TCP-6-BADAUTH: No MD5 digest from [peer's IP address]:11003 to [local router's
IP address]:179

Purpose
Enters global configuration mode.
Enables MD5 password encryption for a TCP connection between two
MSDP peers.
MD5 authentication must be configured with the same password
Note
on both MSDP peers; otherwise, the connection between them
will not be made.
• If you configure or change the password or key, which is used for
MD5 authentication between two MSDP peers, the local device
does not disconnect the existing session after you configure the
password. You must manually disconnect the session to activate
the new or changed password.
Exits global configuration mode and returns to privileged EXEC mode.
(Optional) Displays detailed information about MSDP peers.
Use this command to verify whether MD5 password
Note
authentication is enabled on an MSDP peer.
