Peer Authentication

MSDP supports TCP RSA Data Security, Inc. MD5 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.
