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
Configuring user port attributes
Assigning user ports to an IPv6 multicast VLAN
(Optional.)
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.
•
Do not configure a VLAN as an IPv6 multicast VLAN or an IPv6 sub-VLAN if the VLAN interface
is enabled with IPv6 PIM or MLD. Otherwise, the system displays errors.
•
Do not enable IPv6 PIM or MLD on a VLAN interface if the VLAN interface belongs to an IPv6
multicast VLAN or an IPv6 multicast sub-VLAN. Otherwise, IPv6 multicast forwarding
exceptions occur.
•
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 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.
Configuration procedure
To configure a sub-VLAN-based IPv6 multicast VLAN:
Setting the maximum number of IPv6 multicast VLAN forwarding entries
