[c-nsp] LLQ QoS Question

[Jeff Cartier]

Hi All,

Just a quick question to the group.

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
