The multicast interface is shown as in Figure 5-41.
Multicast is a transmission mode of data packet. When there is multiple-host to receive the
same data packet, multiple-cast is the best option to reduce the broad width and the CPU
load. The source host can just send out one data to transit. This function also depends
on the relationship of the group member and group of the outer.
