Thanks for the quick help.

to my understanding, carrier's carrier VPN establish a
pseudo-carrier over ISP network. What I'm not clear
is, could it be possible to make traffic route inside
that VPN flow through a customer's central node ? 

e.g.

 site-a \
         \
           \
 site-b ----  MPLS-VPN  -- central_node

         /
 site-c /


 traffic from site_a to site_b will be routed to
central node at first, then central_node will process
those traffic after which it is sent to site_be.
