IGMP Snooping Querier
IGMP snooping requires that one central switch or router periodically query all end devices
on the network to announce their Multicast memberships. This central device is the IGMP
querier. The IGMP query responses, known as IGMP reports, keep the switch updated with
the current multicast group membership on a port-by-port basis. If the switch does not
receive updated membership information in a timely fashion, it stops forwarding multicast
transmissions to the port where the end device is located.
