Interoperability Rules for Multicast Routing Protocols

RFC 2715

The rules described in this document will allow efficient interoperation among multiple independent multicast routing domains. Specific instantiations of these rules are given for the DVMRP, MOSPF, PIM-DM, PIM-SM, and CBT multicast routing protocols, as well as for IGMP-only links.  Future versions of these protocols, and any other multicast routing protocols, may describe their interoperability procedure by stating how the rules described herein apply to them.
