Network requirements
As shown in Figure 12, Router A runs IGMPv2 and serves as the IGMP querier, and Switch A runs
IGMPv2 snooping.
To enable Host A and Host B to receive only the multicast data addressed to the multicast group 224.1.1.1,
configure IGMP snooping on Switch A and enable the switch to drop unknown multicast data instead of
flooding it in VLAN 100.

Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 12. (Details not
shown.)
2. On Router A, enable IP multicast routing globally, enable IGMP on Ten-GigabitEthernet 1/0/1,
and enable PIM-DM on each interface.
