The multicast interface is shown as in

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.
