The IESG has received a request from the Protocols for IP Multicast WG (pim) to consider the following document: - 'PIM flooding mechanism and source discovery' <draft-ietf-pim-source-discovery-bsr-07.txt> as Experimental RFC The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2018-01-10. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. Abstract PIM Sparse-Mode uses a Rendezvous Point 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 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.
