Configuring Multicast Forwarding
Defining IGMP Snooping

Defining IGMP Snooping
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.
•
Which 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 accept-
ing members. This results in the creation of the Multicast filtering database. To enable IGMP Snooping:
