Configuring user port attributes
Configuring IPv6 multicast VLAN ports
NOTE:
If you have configured both sub-VLAN-based IPv6 multicast VLAN and port-based IPv6 multicast VLAN
on a device, the port-based IPv6 multicast VLAN configuration is given preference.
Configuring a sub-VLAN-based IPv6 multicast
VLAN
Before you configure a sub-VLAN-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.
Configuration guidelines
• You cannot configure an IPv6 multicast VLAN on a device with IP multicast routing enabled.
• The VLAN to be configured as an IPv6 multicast VLAN must exist.
• The VLANs to be configured as the sub-VLANs of the IPv6 multicast VLAN must exist and must not
be IPv6 multicast VLANs or sub-VLANs of any other IPv6 multicast VLAN.
• The total number of sub-VLANs of an IPv6 multicast VLAN must not exceed the maximum number
the system can support.
Configuration procedure
In this approach, you configure a VLAN as an IPv6 multicast VLAN, and configure user VLANs as
sub-VLANs of the IPv6 multicast VLAN.
To configure a sub-VLAN-based IPv6 multicast VLAN:

as an IPv6 multicast VLAN
and enter IPv6 multicast
