IPv6 multicast VLAN configuration task list
Tasks 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
Setting the maximum number of IPv6 multicast VLAN forwarding entries
When you configure the IPv6 multicast VLANs, follow these guidelines:
•
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.
•
The IPv6 multicast VLAN feature does not take effect on secondary VLANs. As a best practice,
do not configure the IPv6 multicast VLAN feature for secondary VLANs. For more information
about secondary VLAN, see
Layer 2—LAN Switching Configuration Guide
.
Configuring a sub-VLAN-based IPv6 multicast
VLAN
To configure a sub-VLAN-based IPv6 multicast VLAN, configure a VLAN as an IPv6 multicast VLAN,
and 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 restrictions and guidelines
When you configure a sub-VLAN-based IPv6 multicast VLAN, follow these restrictions and
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.
•
Make sure no trunk port exists both in an IPv6 multicast VLAN and a sub-VLAN of the IPv6
multicast VLAN.
Configuration procedure
To configure a sub-VLAN-based IPv6 multicast VLAN:
