Configuring a QinQ Termination Sub-interface and Connecting It to an L3VPN
When users are connected through an L3VPN and each packet that CEs send to PEs carries double VLAN tags, configure a QinQ termination sub-interface and connect it to the L3VPN.
Pre-configuration 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.
