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 RFC2236). 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 P-660 queries all directly connected networks to gather group
membership.
After that, the P-660 updates the information by periodic queries. The P-660
implementation of IGMP is also compatible with version 1. The multicast setting can
be turned on or off on Ethernet and remote nodes.
