Hi Gopal, 

What we're trying to limit is the 'incoming traffic'.
Following your suggestion..
Point 1), means classify traffic on the incoming inteface of PE3, 
Point 2), means apply qos on the outgoing interface of PE1 and PE2
My question is how can PE3 know that  a specific traffic destined to CustA have to use a certain qos
as the traffic is not reach PE1 (where the qos defined) yet.

Thanks, Eddy

Eddy, 
when you talk about 'traffic' be specific as to which
direction. let's say: incoming-traffic = traffic
coming from Internet; out-going traffic = traffic
going to Internet. 

Internet-----PE3-YourCloud--PE1------cust-A
                          \-PE2------cust-b

basic rules: 1)classify traffic on the incoming edge
interface
2)apply qos on the outgoing interfaces on all edge
routers. (if you design well no need to apply qos on
the core routers. if yours is not, then apply qos on
out intf of the core rtrs also)

Now, if you have any questions, pls ask.

rgds,
GOpal

PS: you applied policing which limits traffic. it
won't guarantee.
