3.1.6 IP Multicast

Traditionally, IP packets are transmitted in two ways – unicast or broadcast. Multicast is a third way to
deliver IP packets to a group of hosts. Host groups are identified by Class D IP addresses, i.e., those with
"1110" as their higher-order bits. In dotted decimal notation, host group addresses range from 224.0.0.0 to
239.255.255.255. Among them, 224.0.0.1 is assigned to the permanent IP hosts group and 224.0.0.2 is
assigned to the multicast routers group.
IGMP (Internet Group Management Protocol) is the protocol used to support multicast groups. The latest
version is version 2 (see RFC-2236). IP hosts use IGMP to report their multicast group membership to any
immediate-neighbor multicast routers so the multicast routers can decide if a multicast packet needs to be
forwarded. At start up, the Prestige queries all directly connected networks to gather group membership.
After that, the Prestige updates the information by periodic queries. The Prestige implementation of IGMP is
also compatible with version 1. The multicast setting can be turned on or off on Ethernet and remote nodes.
