VPLS Access Through a QinQ Stacking Sub-interface

To access an Internet Service Provider (ISP) network through a virtual private LAN service (VPLS) network, you can bind a Virtual Switching Instance (VSI) to a VLANIF interface to transparently transmit user VLANs over the ISP network.

Alternatively, you can access a VPLS network through routing-based sub-interfaces on which QinQ stacking is configured. In Figure 1, QinQ stacking sub-interfaces add an outer VLAN tag of the ISP network to its received user packets that carry a VLAN tag ranging from 1 to 200. Then the sub-interfaces are bound to a VSI. In this manner, users can access the VPLS network.
