and Switch D, specifying Switch B as the RPF neighbor of Switch C and Switch C as the RPF neighbor of

Switch D, the receiver hosts can receive the multicast data from the multicast source.

NOTE:

static multicast route is effective only on the multicast router on which it is configured, and will not be

advertised throughout the network or redistributed to other routers.
