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.
