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 to any
upstream multicast switch/router to ensure that it will continue to receive the multicast
service.
Note: Multicast routers use this information, along with a multicast routing protocol such
as DVMRP or PIM, to support IP multicasting across the Internet.
