Re:

Hi Adam,

To answer your first question it's definitely regular QoS as you don't
exchange any labeled packets with your ISP, so there is no MPLS header
to be altered.

The second question depends on how much the 10G link is utilized
between the core and distribution. I would say that QoS would not be
very much of use as most QoS techniques are based on congested links.
It would only have any use if you would implement policing to restrict
certain types of traffic. Again on a 10G link, I would say that's not
really necessary, but I don't have an overview on how much traffic is
flowing over that link :-)
The topology between Core and Distribution is also quite strange. You
terminate MPLS VPNs from ISP to DS? Or are it just VRF sub-interfaces
(VRF-Lite)?
