Internet Group Management Protocol
The IGMP screen allows you to configure the Internet Group Management Protocol
(IGMP) parameters. IGMP is a communications protocol that is used to manage the
membership of Internet Protocol multicast groups. Routers use IGMP to manage
multicasting. The IGMP messages are used to determine which host is part of which
multicast group.
