By configuring a static multicast route in the multicast network, you can change the RPF route and create a multicast path different from the unicast path, from the multicast source to the receiver.
After a static multicast route is configured in the multicast network, a receiver can receive multicast data from a multicast source in another area that is unreachable with unicast routes.
If a network has an area that does not support multicast, configuring a static multicast route to set up a multicast tunnel can implement multicast data forwarding across non-multicast areas.
After a stable-preferred multicast load splitting policy is configured, multicast traffic can be distributed to multiple equal-cost routes for transmission.
