IGMP Snooping Quick Start Configuration Guide

Network configuration

As shown in Figure 1:

·     The network is a Layer 2-only network.

·     The multicast source sends multicast data to multicast group 224.1.1.1.

·     Host A and Host B are receivers of multicast group 224.1.1.1, and Host C is not a receiver of multicast group 224.1.1.1.

·     All host receivers run IGMPv2, and all switches run IGMPv2 snooping. Switch A (which is close to the multicast sources) acts as the IGMP snooping querier.

To send multicast data only to Host A and Host B in the Layer 2-only network, enable IGMP snooping on Switch B.
