MLDv1 Snooping is required on Switch A. Router A acts as theMLD querier.z Switch A’s GigabitEthernet 2/0/1 belongs to VLAN 10, GigabitEthernet 2/0/2 throughGigabitEthernet 2/0/4 belong to VLAN 2 through VLAN 4 respectively, and Host A through Host Care attached to GigabitEthernet 2/0/2 through GigabitEthernet 2/0/4 of Switch A.z The IPv6 multicast source sends IPv6 multicast data to IPv6 multicast group FF1E::101. Host A,Host B, and Host C are receivers of the IPv6 multicast group.z Configure the port-based IPv6 multicast VLAN feature so that Router A just sends IPv6 multicastdata to Switch A through the IPv6 multicast VLAN and Switch A forward the IPv6 multicast data tothe receivers that belong to different user VLANs.
