2.1 QinQ Configuration Example

Note:
Throughout this document, customer VLANs (CVLANs), also called inner VLANs, refer
to the VLANs that a user uses on the private network; and service provider network
VLANs (SVLANs), also called outer VLANs, refer to the VLANs that a service provider
uses to carry VLAN tagged traffic for users.

2.1.1 Network Requirements

A service provider offers VPN services for MAN customers Customer 1 and Customer 2.
For ease of network management and planning, both customers expect the service
provider to forward their traffic with VLAN tags. In addition, the two customers prioritize
traffic by VLAN as follows:
Customer 1: high priority for traffic of CVLANs 20 through 100, normal priority for
traffic of CVLANs 200 through 300, and low priority for traffic of CVLAN 400.
Customer 2: high priority for traffic of CVLANs 300 through 350, normal priority for
traffic of CVLANs 400 through 450, and low priority for traffic of CVLAN 100.
The service provider is required to prioritize the traffic of the two customers based on
their respective traffic priority schemes and keep their traffic separated even when they
are using the same inner VLAN ID. Untagged multicast traffic of the two customers is
transmitted over the specified service provider VLAN based on the same transmission
policy.
The core devices in the service provider network can recognize the TPID 9100 only.
Therefore, you must configure the devices at the distribution layer to set the TPID in
outer VLAN tags to 9100 for interoperability with the core devices.
