I attached the modified version of the diagram. What I want to know exactly is how to do configurations applying QoS and VRF in an MPLS network with any-to-any connectivity setup.

Hi there,

What you are asking for can't be answered in a single post, but lets put the guidelines to start with, you'll need:

1.IGP within the provider cloud between all the Ps and PEs (you can choose from EIGRP, OSPF and ISIS).

2.MP-BGP between the PE routers (you should have full mesh MP-BGP or use Route Reflectors).

3.Each customer CE router shall have a subinterface on the PE router attached to the customer VRF (In the simplest form each customer should have a VRF (configured on each PE the customer is attached to) with a unique Route-target (per AS) and Route Distinguisher(per PE)).

4.As for QoS you can start with Edge QoS, between the PE and the CE. (CE: Classification and Marking, LLQ, WRED, shaping and LFI), PE (Policing, LLQ, WRED and LFI).

You'll have to use the link i've provided in order to be able to do this configuration, and please don't hesitate for further inquiries.

HTH, please rate if it does,
