MSDP
•Multicast Source Discovery Protocol
•draft-ietf-msdp-spec-xx
•Allows each domain to control its own RP(s)
•Interconnect RPs between domains with TCP connections to pass source active messages (SAs)
•Can also be used within a domain to provide RP redundancy (Anycast-RP)
•RPs send SA messages for internal sources to MSDP peers
•SAs are Peer-RPF checked before accepting or forwarding
•RPs learn about external sources via SA messages and may trigger (S,G)joins on behalf of local receivers
•MSDP connections typically parallel MBGP connections
