About IGMP
IGMP manages the membership of hosts and routers in multicast groups. IP hosts use
IGMP to report their multicast group memberships to any immediately neighboring
multicast routers. Multicast routers use IGMP to learn, for each of their attached
physical networks, which groups have members.
IGMP is an integral part of IP and must be enabled on all routers and hosts that want
to receive IP multicasts.
Note: One or more specific routes must exist in the unicast routing table
before a summary address is advertised.
