Multicast Source Discovery Protocol

(MSDP)

Multicast source discovery protocol (MSDP) connects multiple PIM sparse-mode (PIM-SM) domains together.

MSDP peers connect using TCP port 639. Peers send keepalives every 60 seconds. A peer connection is reset

after 75 seconds if no MSDP packets are received. MSDP connections are parallel with MBGP connections.

The Dell Networking OS supports MSDP commands on the S4048–ON platform.
