Multicast Source Discovery Protocol (MSDP)
Overview
MSDP (Multicast Source Discovery Protocol) 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. FTOS supports MSDP commands on the E-Series only, as indicated
by the
e character that appears below each command heading.
