I have some ingress untagged voice traffic coming through the MPLS network and obviously I have some concerns about this traffic being de-prioritised should there is congestion on the MPLS backhaul. In order to mitigate this, I was wondering whether it would be possible to route this traffic through a dedicated VRF across the MPLS network and to allocate some bandwith onto this VRF that would guarantee good voice quality as long as I don't exceed this pre-allocated BW. Does this concept of VRF BW allocation exist? Or are VRFs purely for routing purposes and have nothing to do with BW?
