Information
Static mroutes are used by network administrators to control the reachability of the multicast sources.
If a PIM registered multicast source is reachable via static mroute as well as unicast route, the distance
of each route is examined and the route with shorter distance is the one the PIM selects for reachability.
Note: The default distance of mroutes is zero (0) and is CLI configurable on a per route basis.
