MSDP Peers
•MSDP establishes a neighbor relationship between MSDP peers
•Peers connect using TCP port 639
•Peers send keepalives every 60 secs (fixed)
•Peer connection reset after 75 seconds if no MSDP packets or keepalives are received
•MSDP peers must run mBGP!
•May be an MBGP peer, a BGP peer or both
•Required for peer-RPF checking of the RP address in the SA to prevent SA looping
•Exception: BGP is unnecessary when
peering with only a single MSDP peer (default-peer)
