Overview of MSDP

Overview of MSDP

Multicast Source Discovery Protocol (MSDP) functions to set up an MSDP peer relationship between Rendezvous Points (RPs) in different PIM-SM domains. MSDP peers exchange (S, G) information by sending Source Active (SA) messages. In this manner, MSDP peers share multicast source information and hosts can receive multicast data from the multicast sources in another PIM-SM domain.

MSDP Features Supported

MSDP is used to implement PIM-SM inter-domain multicast and anycast Rendezvous Point (RP) in a PIM-SM domain. You can control connections between MSDP peers, adjust Source Active (SA) message parameters, and configure authentication for MSDP peers and filtering policies for SA messages to enhance MSDP security. The system supports multi-instance MSDP.
