I would configure a shaper to the allocated WAN service bandwidth as a parent policy then have your cbwfq-llq policy as a child to that. (applied outbound towards the service provider)
Depending on the service offered by the SP, they usually police traffic to the subscribed speed meaning packet drops. It is better to shape it on your end and use tools such as WRED for congestion avoidance.

We are about to deploy a few of our routers 'back to back' with the MPLS service providers routers. We will be doing all the markings on our routers and the SP router will be honouring the markings and ensuring QoS toward the MPLS. Since we will be connecting to the SP CPE router at GigE I wasn't planning on configuring any QoS policy-maps facing the SP router My thought was any CBWFQ and LLQ would be done at the SP CPE router as that is point where we will be going from a high speed to low speed link (ie. T1). Even though I'm not doing CBWFQ, would I still need to configure a policy-map with LLQ for voice/video traffic? My understanding has always been QoS isn't applicable on links without congestion. But I also know how LLQ operates...so I'm just unsure of best practice here. Any insights would be appreciated ....jc __________________________________________________________________ DISCLAIMER: This e-mail contains proprietary information some or all of which may be legally privileged.
