ROUTERS DEFINITION (continued): … what to do with the multicast packet. Mrouters currently make up "islands" on the MBone separated by unicast routers. Thus, an mrouter can disguise multicast packets so that they can cross unicast routers. This is done by making each multicast packet look like a unicast packet; the destination address is the next mrouter. This process is called IP tunneling.There are two multicast routing protocols that mrouters use to distribute multicast packets. They are dense-mode routing and sparse-mode routing. … Routers definition sponsored by SearchNetworking.com, powered by WhatIs.com an online computer dictionary
