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 Dell Force10 platforms indicated by the characters

that appear under each of the command headings:

e E-Series, , z Z-Series.
