With Resilient MPLS Rings (RMR), although all existing multicast procedures and solutions can work as is, there are optimizations that could be done for RSVP-TE P2MP tunnel signaling and Fast-ReRouting for both mLDP and RSVP-TE P2MP tunnels. This document describes RMR multicast on a high level, with detailed protocol procedure for RSVP- TE P2MP optimizations specified in a separate document. This document also discusses end to end multicast when there are RMRs.
