Multicast RPF check/equal cost paths

[kswonnell]

What would happen if the RPF check found two equal cost paths to the source in the igp routing table, and we were process switching. Will there be load sharing?

PIM State rules:

General Rule 2 - The RPF interface is computed as the interface with the lowest cost path (based on admin distance/metric) to the IP address of the source (or in the case of a sparse-mode (*,G) entry, the RP). If multiple interfaces have the same cost, the interface with the highest IP address is chosen as the tiebreaker.
