29.1 IGMP Overview
IP multicast is an IETF standard for distributing data to multiple recipients. The following
figure shows a multicast session and the relationship between a multicast server, multicast
routers and multicast hosts. A multicast server transmits multicast packets and multicast
routers forward multicast packets to multicast hosts.
Figure 127 IP Multicast
Server
A host can decide to join or leave a multicast group at any time. A host can also be a member
of more than one multicast group. Multicast groups are identified by IP addresses in the Class
D range (224.0.0.0 to 239.255.255.255). A multicast server sends packets addressed to a
particular multicast group (multicast IP address).
