Configuration prerequisites
Before you configure port-based IPv6 multicast VLAN, complete the following tasks:
• Create VLANs as required
• Enable MLD snooping in the VLAN to be configured as an IPv6 multicast VLAN
• Enable MLD snooping in all user VLANs
Configuring user port attributes
Configure the user ports as hybrid ports to permit packets of the specified user VLAN to pass and
configure the user VLAN to which the user ports belong as the default VLAN.
Configure the user ports to permit packets of the IPv6 multicast VLAN to pass and untag the packets. Thus,
upon receiving multicast packets tagged with the IPv6 multicast VLAN ID from the upstream device, the
Layer 2 device untags the multicast packets and forwards them to its downstream device.

By default, a hybrid port permits
only packets of VLAN 1 to pass.

Layer 2—LAN Switching Command Reference.
Configuring IPv6 multicast VLAN ports
In this approach, you need to configure a VLAN as an IPv6 multicast VLAN and then assign user ports
to this IPv6 multicast VLAN by either adding the user ports in the IPv6 multicast VLAN or specifying the
IPv6 multicast VLAN on the user ports. These two methods give the same result.
