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. The protocol used is determined by available bandwidth and the distribution of end users over the network. If the network has many end users and there is enough bandwidth, dense-mode routing …
