7.8.2.11 Multicast
The multicast interface is shown as in Figure 7-33.
Multicast is a transmission mode of data packet. When there is a multiple-host to receive the

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.
