To do… Use the command… Remarks
Configure the specified
VLAN(s) as sub-VLAN(s) of the
IPv6 multicast VLAN
subvlan vlan-list
Required
By default, an IPv6 multicast
VLAN has no sub-VLANs.
z
The VLAN to be configured as an IPv6 multicast VLAN must exist.
z
The VLANs to be configured as the sub-VLANs of the IPv6 multicast VLAN must exist and must not
be sub-VLANs of another IPv6 multicast VLAN.
z
The total number of sub-VLANs of an IPv6 multicast VLAN must not exceed 63.
Configuring Port-Based IPv6 Multicast VLAN
When configuring 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.
z
A user port can be configured as a multicast VLAN port only if it is of the Ethernet or Layer 2
aggregate port type.
z
Configurations made in Ethernet port view are effective only for the current port; configurations
made in Layer 2 aggregate port view are effective only for the current port; configurations made in
port group view are effective for all the ports in the current port group.
Configuration Prerequisites
Before configuring port-based IPv6 multicast VLAN, complete the following tasks:
z
Create VLANs as required
z
Enable MLD Snooping in the VLAN to be configured as an IPv6 multicast VLAN
z
Enable MLD Snooping in all the 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.
Follow these steps to configure user port attributes:
