However, for senders/receivers it works on IGMP and for routers, its Protocol Independent Multicast (PIM). Router that supports PIM, usually enabled, and multicast group -- 224.0.0.0/4. Try putting up another pc listening in group at other end & send data to multicast group & check if receiver at the otherend receives data.Ify,router network does support multicasting.Few tools online: imj.ucsb.edu/mcast_detective (windows)
