Configuring a QinQ Termination Sub-interface and Connecting It to an L2VPN
When users are connected through an L2VPN and the packets that CEs send to PEs carry double VLAN tags, configure a QinQ termination sub-interface and connect it to the L2VPN to implement interworking between those users.
Pre-configuration Tasks
Before configuring a QinQ termination sub-interface and connecting it to an L2VPN, complete the following tasks:
- Connect devices correctly.
- Configure VLANs to which CEs belong and basic Layer 2 forwarding so that packets sent from CEs to PEs carry double VLAN tags.
- Ensure that the device is not a VCMP client.
