QinAny Mode

In the QinAny mode, the service provider VLAN tag is configured on both the ingress and the egress nodes
of the provider edge VLAN. QinAny mode is similar to QinQ mode using a Type 5 VC, except that the
customer edge VLAN tag is carried in the packet over the pseudowire, as the customer edge VLAN tag is
unknown.

Quality of Service

Using L2VPN technology, you can assign a quality of service (QoS) level to both Port and VLAN modes of
operation.
L2VPN technology requires that QoS functionality on PE routers be strictly L2-payload-based on the
edge-facing interfaces (also know as attachment circuits). The following figure illustrates L2 and L3 QoS
service policies in a typical L2VPN network.
Figure 10: L2VPN QoS Feature Application
The following figure shows four packet processing paths within a provider edge device where a QoS service
policy can be attached. In an L2VPN network, packets are received and transmitted on the edge-facing
interfaces as L2 packets and transported on the core-facing interfaces as MPLS (EoMPLS).
