QoS MPLS VRFs

[Jordi Benet]

Hi guys,

we are creating a new  MPLS cloud with the following VRFs: VRF- Voice, VRF- Data and VRF - Citrix.

My question is: is VRF traffic indepedent from other VRFs (talking about QoS) or I have to request to my MPLS provider to apply QoS?

I would like to have 3 Levels of QoS: Voice, Citrix and Data (that matches with the VRFs).

So it is QoS needed on the MPLS Provider side to increase my traffic performance for voice and Citrix?

Thank you very much for your help.

Ask your provider how you need to mark the voice traffic to prioritize it in their MPLS cloud.

Ok, Thanks for the answer, so you confirm I must Apply QoS éven the traffic is already separated by different VRFS.

Thanks,

Yes VRFs has nothing to do with QoS.

Hi Jordi

You will need to have QOS configured for all the VRFs separately because of two main reasons:

1. Creating a VRF doesn't guarantee that you will get priority.

2. After the traffic enters the Service Provider backbone its all MPLS traffic and many customers share the same backbone, so to have an effective treatment of your traffic you will need to define proper QOS.

Agree with lion man that QoS and VRF are different things. However some providers, especially the old one which are legacy cannot support multiple QoS priorities within the same VPN and hence would ask for one VRF per QoS group. We had some Nortel boxes as PEs and configured one PVC per service.
