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 IPv6 Sub-VLAN-Based IPv6 Multicast VLAN 

Before configuring sub-VLAN-based IPv6 multicast VLAN, complete the following tasks: 

z 

Create VLANs as required 

z 

Enable MLD Snooping in the VLAN to be configured as an IPv6 multicast VLAN 

Configuring Sub-VLAN-Based IPv6 Multicast VLAN 

In this approach, you configure a VLAN as an IPv6 multicast VLAN, and configure user VLANs as 

sub-VLANs of the IPv6 multicast VLAN.  

Follow these steps to configure sub-VLAN-based IPv6 multicast VLAN: 

Enter system view 

— 

Configure the specified VLAN 
as an IPv6 multicast VLAN and 
enter IPv6 multicast VLAN view 

multicast-vlan ipv6 vlan-id 

Required 

No IPv6 multicast VLAN 
configured by default 

Configure the specified 
VLAN(s) as sub-VLAN(s) of the 
IPv6 multicast VLAN 

subvlan vlan-list 

Required 

By default, an IPv6 multicast 
VLAN has no sub-VLANs.  

 

z 

You cannot configure IPv6 multicast VLAN on a device with IP multicast routing enabled. 

z 

The VLAN to be configured as an IPv6 multicast VLAN must exist.  

z 

The VLANs to be configured as the sub-VLANs of the IPv6 multicast VLAN must exist and must not 

be sub-VLANs of another IPv6 multicast VLAN.  

z 

The total number of sub-VLANs of an IPv6 multicast VLAN must not exceed the maximum number 

the system can support (an S7900E series Ethernet switch supports up to five IPv6 multicast 

VLANs, and supports up to 4000 sub-VLANs for each multicast VLAN. The total number of 

sub-VLANs for all multicast VLANs on the switch cannot exceed 4000).
