6.14 Multicast
IP multicast is a method of forwarding the same set of IP packets to a number of
hosts within a network. You can use multicast in both IPv4 and IPv6 networks to
provide efficient delivery of data to multiple destinations.
Multicast involves both a method of delivery and discovery of senders and receivers
of multicast data, which is transmitted on IP multicast addresses called groups. A
multicast address that includes a group and source IP address is often referred to as
a channel.
