IGMP snooping configuration examples
Group policy and simulated joining configuration example
Network requirements
• As shown in Figure 13 , Router A connects to the multicast source through Ethernet 1/0/2 and to
Switch A through Ethernet 1/0/1.
• IGMPv2 is required on Router A, IGMPv2 snooping is required on Switch A, and Router A will act
as the IGMP querier on the subnet.
• The receivers, Host A and Host B, attached to Switch A can receive multicast traffic addressed to
multicast group 224.1.1.1 only.
• Multicast data for group 224.1.1.1 can be forwarded through Ethernet 1/0/3 and Ethernet 1/0/4
of Switch A even if Host A and Host B accidentally, temporarily stop receiving multicast data.

Configuration procedure
1. Configure IP addresses
Configure an IP address and subnet mask for each interface according to Figure 13 . The 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.
