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:
Figure 4-8-4 IGMP State Transitions
IGMP Querier
A router, or multicast-enabled switch, can periodically ask their hosts if they want to receive multicast traffic. If there is more
than one router/switch on the LAN performing IP multicasting, one of these devices is elected “querier” and assumes the
role of querying the LAN for group members. It then propagates the service requests on to any upstream multicast
switch/router to ensure that it will continue to receive the multicast service.
Multicast routers use this information, along with a multicast routing p
rotocol such as
DVMRP or PIM, to support IP multicasting across the Internet.
