> I'm just playing and trying to understand ethernet-to-ethernet QoS in a
service provider environment, be it from a dot1q frame using CoS or a
dot1q-tunnel again using CoS to using CoS in the MPLS header ideally I just
want what ever extended ping from the customer devices to copy the IPP over to
the dot1q CoS then over again to CoS in the MPLS header

cannot map dynamic CoS to EXP bits on label imposition from the interface
facing the CE routers, I can only map the topmost label on imposition to a
specific CoS value in the MPLS header therefore this isn't dynamic in nature

ldp to PE1)  ------ dot1q CE2

> My second question is if the customer wanted a 2mbps VPN then I can shape
2000kbps outbound and police inbound to 2000kbps facing the CE devices or ask
the customer to use shaping outbound in place of the PE policing inbound, is
their an RSVP or VFI QoS applied in provider environments, essentially how do
I go about this and what is common practice
