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 Sparse Mode (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.}, }
