2. Configure Router A:
# Enable IPv6 multicast routing.
<RouterA> system-view
[RouterA] ipv6 multicast routing
[RouterA-mrib6] quit
# Enable MLD on Ten-GigabitEthernet 1/1/5.
[RouterA] interface ten-gigabitethernet 1/1/5
[RouterA-Ten-GigabitEthernet1/1/5] mld enable
[RouterA-Ten-GigabitEthernet1/1/5] quit
# Enable IPv6 PIM-DM on Ten-GigabitEthernet 1/1/6.
[RouterA] interface ten-gigabitethernet 1/1/6
[RouterA-Ten-GigabitEthernet1/1/6] ipv6 pim dm
[RouterA-Ten-GigabitEthernet1/1/6] quit
3. Configure Switch A:
# Enable MLD snooping globally.
<SwitchA> system-view
[SwitchA] mld-snooping
[SwitchA-mld-snooping] quit
# Create VLAN 100, assign Ten-GigabitEthernet 1/1/5 through Ten-GigabitEthernet 1/1/7 to
