What is ipMRouteRtMask?

This value reports the network mask associated with the unicast route used to find the upstream or parent interface for this multicast forwarding entry. An admin pairs it with the corresponding route address to see exactly which unicast route the router's multicast RPF check is relying on. For example, a mask of 255.255.255.0 paired with the route address shows the RPF lookup matched a /24 route in the unicast table.
