IGMP packets enable multicast routers to keep track of the membership of multicast groups, on their respective sub networks. 

The following outlines what is communicated between a multicast router and a multicast group member using IGMP. 

A host sends an IGMP 

“report”

 to join a group 

A host will never send a report when it wants to leave a group (for version 1). 

A host will send a

 “leave” 

report when it wants to leave a group (for version 2). 

Multicast routers send IGMP queries (to the all-hosts group address: 224.0.0.1) periodically to see whether any group members 

exist on their sub networks. If there is no response from a particular group, the router assumes that there are no group members 

on the network. 

The Time-to-Live (TTL) field of query messages is set to 1 so that the queries will not be forwarded to other sub networks. 

IGMP version 2 introduces some enhancements such as a method to elect a multicast queried for each LAN, an explicit leave 

message, and query messages that are specific to a given group. 

The states a computer will go through to join or to leave a multicast group are shown below:
