9.2.5 IGMP v2 Snooping
Layer 2 switches can use IGMP snooping to constrain the flooding of multicast traffic by
dynamically configuring Layer 2 interfaces so that multicast traffic is forwarded to only
those associated with IP multicast devices. Internet Group Management Protocol (IGMP)
is the internet protocol that helps to inform multicast groups to multicast router. In the mul-
ticast network, multicast router sends only IGMP query massage that quest whether re-
ceive multicast packet when multicast packet is transmitted. If a switch sends the join
massage to multicast router, multicast router transmits the multicast packet only to that
switch.
