IPv6 multicast VLAN configuration example
IMPORTANT:
By default, Ethernet interfaces, VLAN interfaces, and aggregate interfaces are in the state of DOWN. To
configure such an interface, use the undo shutdown commands to bring it up first.
Network requirements
As shown in Figure 89 , MLDv1 runs on Router A, and MLDv1 snooping runs on Switch A. Router A acts
as the MLD querier.
The IPv6 multicast source sends IPv6 multicast data to the IPv6 multicast group FF1E::101. Host A, Host B,
Host C, and Host D are receivers of the IPv6 multicast group. The hosts belong to VLAN 2 through VLAN
5.
Configure the sub-VLAN-based IPv6 multicast VLAN feature on Switch A 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 on each device and configure an IPv6 address and address prefix for
each interface as shown in Figure 89 . (Details not shown.)
2. On Router A, enable IPv6 multicast routing, enable IPv6 PIM-DM on each interface and enable
MLD on the host-side interface GigabitEthernet 3/0/2.
