IGMP snooping configuration example
Network requirements
• As shown in Figure 112, Router A connects to a multicast source (Source) through Ethernet 1/2, and
to the AP through Ethernet 1/1.
• The multicast source sends multicast data to group 224.1.1.1. Host A is a receiver of the multicast
group.
• IGMPv2 runs on Router A and IGMP snooping version 2 runs on the AP.
• The function of dropping unknown multicast packets is enabled on the AP to prevent the AP from
flooding multicast packets in the VLAN if no corresponding Layer 2 forwarding entry exists.
