IPv6 multicast VLAN configuration task list
Task at a glance
(Required.) Perform one of the following tasks:
• Configuring a sub-VLAN-based IPv6 multicast VLAN
• Configuring a port-based IPv6 multicast VLAN
{ Configuring user port attributes
{ Assigning user ports to an IPv6 multicast VLAN
(Optional.) Setting the maximum number of IPv6 multicast VLAN forwarding entries
If you have configured both a sub-VLAN-based IPv6 multicast VLAN and a port-based IPv6 multicast
VLAN on a device, the port-based IPv6 multicast VLAN configuration takes effect.
Configuring a sub-VLAN-based IPv6 multicast
VLAN
You must first configure a VLAN as an IPv6 multicast VLAN, and then assign the VLANs that contain
multicast receivers to the IPv6 multicast VLAN as sub-VLANs.
Configuration prerequisites
Before you configure a sub-VLAN-based IPv6 multicast VLAN, complete the following tasks:
• Create VLANs as required.
• Enable MLD snooping for the VLAN to be configured as the IPv6 multicast VLAN, and for the
VLANs to be configured as sub-VLANs.
Configuration guidelines
When you configure a sub-VLAN-based IPv6 multicast VLAN, follow these guidelines:
• The VLAN to be configured as the IPv6 multicast VLAN must exist.
• A VLAN to be configured as a sub-VLAN must exist and cannot be an IPv6 multicast VLAN or a
sub-VLAN of any other IPv6 multicast VLANs.
• The total number of IPv6 multicast VLANs on a device cannot exceed the upper limit.
Configuration procedure
To configure a sub-VLAN-based IPv6 multicast VLAN:
Step Command Remarks
1. Enter system view.
system-view
N/A
2. Configure a VLAN as an
IPv6 multicast VLAN and
enter its view.
ipv6 multicast-vlan
vlan-id
By default, a VLAN is not an IPv6
multicast VLAN.
3. Assign the specified VLANs
to the IPv6 multicast VLAN
as sub-VLANs.
subvlan
vlan-list
By default, an IPv6 multicast VLAN does
not have any sub-VLANs.
