Network requirements
z Router A connects to a multicast source through GigabitEthernet1/0/1 and to Switch A, through
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.
z 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.
