To change the Reverse Path Forwarding (RPF) route and create a multicast path different from the source-to-receiver unicast path, configure multicast static routes on the multicast network.
After multicast static routes are configured, a receiver can receive multicast data from a multicast source in another area that is unreachable with unicast routes.
On a PIM-SM network where multicast services are stable, configure the stable-preferred multicast load splitting policy so that multicast traffic can be distributed to multiple equal-cost routes for transmission.
