Network requirements
As shown in Figure 14, IGMPv2 runs on Router A, IGMPv2 snooping runs on Router B, and Router A acts
as the IGMP querier on the subnet. Router B is an HSR6800 router.
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 2/0/3 and
GigabitEthernet 2/0/4 of Router B even if Host A and Host B accidentally, temporarily stop receiving
multicast data. Router B drops unknown multicast data and does not broadcast the data to the VLAN
where Router B resides.
