Basic principle of the protocol:? IGMP is a control protocol between router and PC；? PC reports to the router the multicast group which it wants to join in ；? Router query the work if there is still any member of a specific multicast group.HUAWEI TECHNOLOGIES CO.， LTD. HUAWEI Confidential Page 49IGMP Version 1? Two types of messages：? Membership Query ? Membership Queries are sent by IP multicast routers to query the multicast reception state of neighboring interfaces. ? Membership Report ? Membership Reports are sent by PCs to inform IP multicast routers of its own membership HUAWEI TECHNOLOGIES CO.， LTD. HUAWEI Confidential Page 50IGMP Version 2? Three types of message：? Membership Query, two subtypes of Membership Query messages:? General Query: used to learn which groups have members on an attached work.?
