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
Configuration Prerequisites
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:
To do… Use the command… Remarks
Enter system view 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).
