IGMP snooping configuration examples Group policy and simulated joining configuration example Network requirements As shown in Figure 13, IGMPv2 runs on Router A, IGMPv2 snooping runs on Switch A, and Router A acts as the IGMP querier on the subnet. The receivers, Host A and Host B, 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 GigabitEthernet 1/0/3 and GigabitEthernet 1/0/4 of Switch A even if Host A and Host B accidentally, temporarily stop receiving multicast data, and that Switch A drops unknown multicast data and does not broadcast the data to the VLAN where Switch A resides. Figure 13 Network diagram Configuration procedure 1. Configure an IP address and subnet mask for each interface as per Figure 13. (Details not shown.) 2. On Router A, enable IP multicast routing, enable IGMP on GigabitEthernet 1/0/1, and enable PIM-DM on each interface. system-view [RouterA] multicast routing-enable [RouterA] interface gigabitethernet 1/0/1 [RouterA-GigabitEthernet1/0/1] igmp enable [RouterA-GigabitEthernet1/0/1] pim dm [RouterA-GigabitEthernet1/0/1] quit [RouterA] interface gigabitethernet 1/0/2 [RouterA-GigabitEthernet1/0/2] pim dm [RouterA-GigabitEthernet1/0/2] quit 3. Configure Switch A: # Enable IGMP snooping globally. 33
