Remarks

Multicast routers send Group Membership Query messages to learn which groups have members on each of their attached physical networks. Host computers respond to a Group Membership Query message by sending a Group Membership Report for each multicast group joined by the host. A host computer can also send a Group Membership Report when it joins a new multicast group. Group Membership Reduction messages are sent when a host computer leaves a multicast group.
