Huawei AR530 Series - Configuring Selective Qinq

The Ethernet sub-interface is added to the bridge group.
Step 6 Run:
bridge vlan-transmit enable
The interface is enabled to transparently transmit VLAN IDs.
Step 7 Run:
vlan allow-pass { vid vlan-id1 [ to vlan-id2 ] | default }
The VLAN allowed by the Ethernet sub-interface is configured.
NOTE
VLANs allowed by all sub-interfaces of a main interface cannot overlap.
The vlan allow-pass default command can be executed only on a sub-interface among all sub-interfaces of each
main interface. Packets are forwarded through the default sub-interface when the packets do not match other
QinQ or VLAN mapping entries on a sub-interface.
Step 8 Run:
vlan dot1q-tunnel tunnel-vlan-id [ native vid native-vlan-id ]
The basic QinQ function is configured on a sub-interface.
The vlan dot1q-tunnel command can be only executed at one time on a sub-interface and the
VLAN specified by tunnel-vlan-id must be allowed by the sub-interface.

4.6.1.2 Configuring Selective QinQ
Context
You can configure either of the following selective QinQ modes:
l VLAN ID-based selective QinQ
When private networks connect to a carrier network through CEs and PEs, run the vlan
stacking command on CE interfaces connected to PEs so that the CE interfaces add the
outer VLAN tag allocated by the carrier to user packets. This implementation saves VLAN
IDs and allows user packets to be transparently transmitted on the carrier network.
l 802.1p priority-based selective QinQ
An 802.1p priority indicates a packet priority. Generally, different services of a user use
different priorities. A carrier can establish different data transmission networks for different
services based on 802.1p priorities so that services on the carrier network can be
differentiated.
Procedure
l Configure VLAN ID-based selective QinQ.
