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.

The commands are:

• clear ip msdp peer

• clear ip msdp sa-cache

• debug ip msdp

• ip msdp cache-rejected-sa

• ip msdp default-peer

• ip msdp mesh-group

• ip msdp originator-id

• ip msdp peer
