Step 3. Configure the specified VLANs as sub-VLANs of the IPv6 multicast VLAN. Command subvlan vlan-list Remarks By default, an IPv6 multicast VLAN has no sub-VLANs. Configuring a port-based IPv6 multicast VLAN When you configure a port-based IPv6 multicast VLAN, you need to configure the attributes of each user port and then assign the ports to the IPv6 multicast VLAN. A user port can be configured as a multicast VLAN port only if it is an Ethernet port or Layer 2 aggregate interface. In Ethernet interface view or Layer 2 aggregate interface view, configurations that you make are effective only on the current interface. Configuration prerequisites Before you configure a port-based IPv6 multicast VLAN, complete the following tasks: • Enable IPv6 forwarding. • Create VLANs as required. • Enable MLD snooping in the VLAN to be configured as an IPv6 multicast VLAN. • Enable MLD snooping in all the user VLANs. Configuring user port attributes First, 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. Then, configure the user ports to permit packets of the IPv6 multicast VLAN to pass and untag the packets. After 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. To configure user port attributes: Step 1. Enter system view. 2. Enter Layer 2 Ethernet interface view or Layer 2 aggregate interface view. 3. Configure the user port link type as hybrid. 4. Specify the user VLAN that comprises the current user ports as the default VLAN. 5. Configure the current user ports to permit packets of the specified IPv6 multicast VLAN to pass and untag the packets. Command system-view interface interface-type interface-number port link-type hybrid port hybrid pvid vlan vlan-id port hybrid vlan vlan-id-list { tagged | untagged } Remarks N/A Use either command. Access by default. VLAN 1 by default. By default, a hybrid port permits only packets of VLAN 1 to pass. 242
