Network requirements
As shown in Figure 14, 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.
