Each Protocol Independent Multicast - Sparse Mode (PIM-SM) router in
a PIM domain that supports Any Source Multicast (ASM) maintains
Group-to-RP mappings that are used to identify a Rendezvous Point
(RP) for a specific multicast group. PIM-SM has defined an algorithm
to choose a RP from the Group-to-RP mappings learned using various
mechanisms. This algorithm does not consider the PIM mode and the
mechanism through which a Group-to-RP mapping was learned.
This document defines a standard algorithm to deterministically
choose between several Group-to-RP mappings for a specific group.
This document first explains the requirements to extend the
Group-to-RP mapping algorithm and then proposes the new algorithm.
