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.
clear ip msdp peer

Syntax
clear ip msdp peer {
peer address
}
Parameters
peer address
Enter the peer address in a dotted decimal format (A.B.C.D.)
