Technical Summary
PIM Sparse-Mode (PIM-SM) uses a Rendezvous Point (RP) and shared
trees to forward multicast packets from new sources. Once last hop
routers receive packets from a new source, they may join the Shortest
Path Tree for the source for optimal forwarding. This draft defines
a new mechanism that provides a way to support PIM-SM without the
need for PIM registers, RPs or shared trees. Multicast source
information is flooded throughout the multicast domain using a new
generic PIM flooding mechanism. This allows last hop routers to
learn about new sources without receiving initial data packets.
Working Group Summary
There has only been positive feedback for moving this draft to an
experimental RFC. We have complete consensus for progressing this
document after face to face meeting discussions and on the list.
Document Quality
There is at least one implementation and a couple of deployments.
