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 S7500E 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).
