1/0/1, and to Switch A through GigabitEthernet 1/0/2.
IGMPv2 is required on Router A. IGMPv2 Snooping is required on Switch A. Router A acts as the
IGMP querier.
Switch A's GigabitEthernet 1/0/1 belongs to VLAN 10, GigabitEthernet 1/0/2 through
GigabitEthernet 1/0/4 belong to VLAN 2 through VLAN 4 respectively, and Host A through Host C
are attached to GigabitEthernet 1/0/2 through GigabitEthernet 1/0/4 of Switch A respectively.
The multicast source sends multicast data to multicast group 224.1.1.1. Host A, Host B, and Host C
are receivers of the multicast group.
Configure the port-based multicast VLAN feature so that Router A just sends multicast data to
Switch A through the multicast VLAN and Switch A forwards the multicast data to the receivers that
