IGMP must be currently enabled. An error message is displayed on the CLI if multicast routing is

sourceipaddr and the mask fields specify the network IP address of the multicast packet source. The
rpfipaddr is the IP address of the next hop toward the source. metric is the cost of the route entry
for comparison with other routes to the source network. The current incoming interface is used for
RPF checking for multicast packets matching this multicast static route entry.
