Configure the sub-VLAN-based IPv6 multicast VLAN feature so that Router A just sends IPv6
multicast data to Switch A through the IPv6 multicast VLAN and Switch A forwards the traffic to
the receivers that belong to different user VLANs.

Configuration procedure
1) Enable IPv6 forwarding and configure IPv6 addresses
Enable IPv6 forwarding on each device and configure an IPv6 address and address prefix for each
interface as per Figure
2) Configure Router A
# Enable IPv6 multicast routing, enable IPv6 PIM-DM on each interface and enable MLD on the
host-side interface GigabitEthernet 1/0/2.
<RouterA> system-view
[RouterA] multicast ipv6 routing-enable
[RouterA] interface gigabitethernet 1/0/1
[RouterA-GigabitEthernet1/0/1] pim ipv6 dm
[RouterA-GigabitEthernet1/0/1] quit
[RouterA] interface gigabitethernet 1/0/2
[RouterA-GigabitEthernet1/0/2] pim ipv6 dm
[RouterA-GigabitEthernet1/0/2] mld enable
3) Configure Switch A
# Enable MLD Snooping globally.
<SwitchA> system-view

[SwitchA-mld-snooping] quit
# Create VLAN 2 and assign GigabitEthernet 1/0/2 to this VLAN.
