What is ipMRouteSourceMask?

This read-only IpAddress gives the network mask applied to the source address for a multicast-route entry. An admin uses this to know whether a route entry matches an individual source host or an entire source subnet. For example, a mask of 255.255.255.255 shows this route entry is specific to a single source host rather than a whole source network.
