3.4 IGMP Snooping Configuration Examples

3.4.1 Configuring IGMP Snooping

I. Network requirements
To prevent multicast traffic from being flooded at Layer 2, enable IGMP snooping on
Layer 2 switches.
As shown in
Ethernet 1/0/2, and to Switch A through Ethernet 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.

III. Configuration procedure
1) Configure the IP address of each interface
Configure an IP address and subnet mask for each interface as per
detailed configuration steps are omitted.
2) Configure Router A
# Enable IP multicast routing, enable PIM-DM on each interface, and enable IGMP on
Ethernet 1/0/1.
