When we say Multicast the first thing that comes to mind is some species Routing protocol such as EIGRP & RIPv2 & OSPF.
the Date transmitted on the network within the scope of Class D reserved IP

For example, when the EIGRP protocol wants to exchange the Route Table with the other protocols he publish the trafic on Ip 184.108.40.206
In this case, the contributions in the case of routers listen for any packets carrying Ip 220.127.116.11
The Traffic Moving in a Network according the specific rules by the sender, for example Closer device on the network or the best Path of Traffic.
