Abstract:
PIM Sparse-Mode uses a Rendezvous Point (RP) and shared trees to
forward multicast packets to Last Hop Routers (LHR). After the first
packet is received by the LHR, the source of the multicast stream is
learned and the Shortest Path Tree (SPT) can be joined. This draft
proposes a solution 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 mechanism is defined in this document, and
is modeled after the PIM Bootstrap Router protocol. By removing the
need for RPs and shared trees, the PIM-SM procedures are simplified,
improving router operations, management and making the protocol more
robust.
