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 , S4810 systems,

as indicated by the

Z characters that appears below each command heading.
