Hi folks,

I have some trouble to find informations about this topic.
I'm marking the packets on the egress PE  on an Interfaces that is in a VRF with the commands "match input interface" in a class map, and "set mpls experimental" in the policy map, then I apply this to the policy to the input interface. example :

class-map VPN_A
  match input interface GigabitEthernet1/1

policy-map VPN_PMAP
  class VPN_A
      set mpls experimental 3

interface GigbitEthernet1/1
  ip vrf forwarding vrf1
  service-policy input VPN_PMAP

I asume that this will set the exp fields bottom label stack entry ? How will the next P box be able to read the Exp bits ? Is the Exp field of the bottom label stack entry copied into the top label stack entry ?

Thanks for your help,
Yves
