IP Multicast Routing Protocol

IGMP

IGMP
Computers and network devices that want to receive multicast transmissions need to inform nearby routers that
they will become members of a multicast group. The Internet Group Management Protocol (IGMP) is used to
communicate this information. IGMP is also used to periodically check the multicast group for members that are no
longer active.
In the case where there is more than one multicast router on a subnetwork, one router is elected as the 'querier'.
This router then keeps track of the membership of the multicast groups that have active members. The information
received from IGMP is then used to determine if multicast packets should be forwarded to a given subnetwork or
not. The router can check, using IGMP, to see if there is at least one member of a multicast group on a given
subnetwork. If there are no members on a subnetwork, packets will not be forwarded to that subnetwork.
