P-660 Series Support Notes
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.
