The output shows that MLD snooping is maintaining the router port in the IPv6 multicast VLAN (VLAN 10)
and the member ports in the sub-VLANs (VLAN 2 through VLAN 5).
Port-based multicast VLAN configuration example
Network requirements
• As shown in Figure 81 , Router A connects to an IPv6 multicast source (Source) through
GigabitEthernet 1/0/1, and to Switch A through GigabitEthernet 1/0/2.
• MLDv1 runs on Router A. MLDv1 snooping runs on Switch A. Router A acts as the MLD querier.
• 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. The hosts belong to VLAN 2 through VLAN
4 respectively.
• Configure the port-based IPv6 multicast VLAN feature on Switch A so that Router A sends IPv6
multicast data to Switch A through the IPv6 multicast VLAN, and Switch A forwards the IPv6
multicast data 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 the IPv6 address and address prefix for each
interface as per Figure 81 . (details not shown)
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.
