GigabitEthernet 1/0/2.
z IGMPv2 is required on Router A, and IGMPv2 Snooping is required on Switch A. Router A is the
IGMP querier.
z Switch A’s GigabitEthernet 1/0/1 belongs to VLAN 10, GigabitEthernet 1/0/2 through
GigabitEthernet1/0/4 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.
