IGMP Snooping Configuration
When IGMP snooping is enabled, all IGMP packets are forwarded to the CPU. The CPU analyzes
the incoming packets and determines which ports want to join which Multicast groups, which
ports have Multicast routers generating IGMP queries, and what routing protocols are forwarding
packets and Multicast traffic. A port requesting to join a specific Multicast group issues an IGMP
report specifying that Multicast group. This results in the creation of the Multicast filtering
database.
