Router A is the MLDquerier.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 the IPv6 multicast group FF1E::101. Host A,Host B, and Host C are receivers of the IPv6 multicast group.z Configure the sub-VLAN-based IPv6 multicast VLAN feature so that Router A just sends IPv6multicast data to Switch A through the IPv6 multicast VLAN and Switch A forwards the traffic to thereceivers that belong to different user VLANs.Figure 1-4 Network diagram for sub-VLAN-based IPv6 multicast VLAN configurationSourceReceiverHost AVLAN 2GE2/0/2GE2/0/3GE2/0/4Switch AMLD querierRouter AGE2/0/11:2/64GE2/0/22001::1/641::1/64ReceiverHost BVLAN 3ReceiverHost CVLAN 4GE2/0/1Configuration procedure1) Enable IPv6 forwarding and configure IPv6 addresses
