Huawei AR530 Series - Configuring Qinq

l Before configuring QinQ on an interface, add the interface to a network bridge. If the
interface is deleted from the network bridge, the QinQ configuration is also deleted from
the interface.
l You can configure only QinQ, selective QinQ, or VLAN mapping on a sub-interface.
4.6 Configuring QinQ
This section describes how to configure QinQ.
4.6.1 Configuring QinQ Tunneling
This section describes how to configure QinQ tunneling, including basic QinQ and selective
QinQ.
4.6.1.1 Configuring Basic QinQ
Background
Dot1q tunnel isolates a carrier network from a user network and is widely used when users
connect to a carrier network. When private networks connect to a carrier network through CEs
and PEs, run the vlan dot1q-tunnel 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.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
bridge bridge-id
A bridge group is created and the bridge group view is displayed.
Step 3 Run:
quit
Exit from the bridge group view.
Step 4 Run:
interface { ethernet | gigabitethernet } interface-number.subinterface-number
The Ethernet sub-interface view is displayed.
NOTE
Sub-interfaces can only be created on Layer 3 Ethernet interfaces. If an interface works in Layer 2 mode
and supports switching between Layer 2 and Layer 3 modes, run the undo portswitch command to switch
the interface in Layer 3 mode before creating a sub-interface on the interface.
Step 5 Run:
bridge bridge-id
