IP hosts use Internet Group Management Protocol (IGMP) to report their multicast group
memberships to neighbor routers. Similarly, multicast routers use IGMP to discover which of their
hosts belong to multicast group. The router supports IGMP proxy that handles IGMP message.
When enabled, the router will act as a proxy for a LAN host making request to join and leave
multicast groups, and a multicast router sending multicast packets to multicast groups on WAN side.
