IGMP Snooping Configuration Examples

Configuring IGMP Snooping

Network requirements
To prevent multicast traffic from being flooded at Layer 2, enable IGMP snooping on Layer 2 switches.
As shown in
1/0/2, and to Switch A through GigabitEthernet 1/0/1.
Run PIM-DM and IGMP on Router A. Run IGMP snooping on Switch A. Router A acts as the IGMP
querier.
The multicast source sends multicast data to the multicast group 224.1.1.1. Host A and Host B are
receivers of the multicast group 224.1.1.1.
