Protocol Independent Multicast - Sparse Mode (PIM-SM) uses a
Rendezvous Point (RP) and shared trees to forward multicast packets
from new sources. Once Last-Hop Routers (LHRs) receive packets from
a new source, they may join the Shortest Path Tree (SPT) for the
source for optimal forwarding. This document 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 (PFM). This allows LHRs to learn about new
sources without receiving initial data packets.
This document is a product of the Protocols for IP Multicast Working Group of the IETF.
