multicast VLAN on Switch B. Switch B replicates the IPv6 multicast data and sends a separate copy to
each user port in the IPv6 multicast VLAN.
IPv6 multicast VLAN configuration task list
Task at a
lance
(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
When you configure 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.
• HP recommends that you not configure IPv6 multicast VLANs on a device with IP multicast routing
enabled.
Configuring a sub-VLAN-based IPv6 multicast
VLAN
To configure a sub-VLAN-based IPv6 multicast VLAN, you must configure a VLAN as an IPv6 multicast
VLAN, and assign the VLANs that contain receiver hosts 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 must not 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 must not exceed the system upper limit.
Configuration procedure
