Peer Authentication

MSDP (Multicast Source Discovery Protocol) supports TCP RSA Data Security, Inc. MD5 (Message-Digest algorithm 5) Message-Digest Algorithm authentication (RFC 2385) to secure control messages between MSDP peers. You must configure a secret password for an MSDP peer session to enable TCP RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication. When a password is configured, MSDP receives only authenticated MSDP messages from its peers. All MSDP messages that fail TCP RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication are dropped.

Configure TCP RSA Data Security, Inc. MD5 Message-Digest Algorithm authentication on an MSDP peer using the command:
configure msdp peer [remoteaddr | all] password [none | {encrypted} tcpPassword] {vr vrname}
Remove the password using the command:
configure msdp peer {all | remoteaddr} password none

The password displays in encrypted format and cannot be seen as simple text. Additionally, the password is saved in encrypted format.
Display the password in encrypted format using the command:
show msdp [peer {detail} | {peer} remoteaddr] {vr vr_name}
