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

m u l t ic a s t g ro u p 224 .1.1.1 o n l y.

• 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. T

he 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.
