L2VPN QoS

IP Header Compression QoS: Example

In this example, IPHC is configured through QoS as an action under the class map using the compress
header ip command.
The packets are classified according to the criteria in the class maps. The policy map specifies which
behavior to apply to which classes. IPHC is enabled using the compress header ip action for the class.
An IPHC profile with a QoS service policy is attached to a serial interface.

L2VPN QoS
This section describes the following Frame Relay L2VPN deployment scenarios:
•
•
There are local-connect variants of these scenarios that do not go over a pseudowire. This discussion
Note
focuses on the pseudowire scenarios.
Frame Relay <-> Frame Relay Over Pseudowire: Example
This example shows that you can match based on the Frame Relay DLCI on the ingress Frame Relay
interface on router PE1 and set the fr-de value. This configuration is carried over the L2VPN pseudowire.
When the Frame Relay packet exits router PE2 through the Frame Relay l2transport interface, the fr-de
value is intact.
This configuration allows you to manipulate and carry over the Frame Relay QoS values across L2VPN.
