10 | CONFIGURING IGMP SNOOPING |
|
This section contains information for configuring 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 accepting members. This results in the creation of the Multicast filtering database.
