IGMP Snooping
In a point-to-multipoint network, packets can be sent in three ways: unicast, broadcast
and multicast. With unicast, many copies of the same information will be sent to all the
receivers, occupying a large bandwidth.
With broadcast, information will be sent to all users in the network no matter they need it or
not, wasting network resources and impacting information security.
Multicast, however, solves all the problems caused by unicast and broadcast. With
multicast, the source only needs to send one piece of information, and all and only the users
who need the information will receive copies of the information. In a point-to-multipoint
network, multicast technology not only transmits data with high efficiency, but also saves a
large bandwidth and reduces network load.
When IGMP Snooping is disabled on the switch, multicast packets will be broadcast in
the Layer 2 network; when IGMP Snooping is enabled on the switch, multicast data from
