Configuring Switch Information 325
When IGMP Snooping is enabled globally, 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.
What routing protocols are forwarding packets and Multicast traffic.
Ports requesting to join a specific Multicast group issue an IGMP report, specifying that Multicast
group is accepting members. This results in the creation of the Multicast filtering database.
