Is it possible to use QoS for customers traffic on PE core int ?

[gongya001]

I have the following ingress packet on PE core facing interface from one customer. Should I use exp from mpls header or dscp in ip header ?

thanks !!

According to Cisco documentation:

• If a packet is encapsulated in MPLS, the MPLS payload cannot be checked for other protocols such as IP for classification or marking. Only MPLS EXP marking affects packets encapsulated by MPLS.
