[c-nsp] QoS Order of Operation in an MPLS environment

[Yasser Aly]

Hello,

 

  I would like to know what is the order of operation for QoS inside a
PE-router.

 

For the incoming packets from CE to PE router, inside the PE, will the
packet tagged with the MPLS EXP once entered the VRF, or I will match and
set ip prec values and PE will automatically translate it to the MPLS world
inside the Provider core network.

 

Any links elaborating this are highly appreciated.

 

Regards,

Yasser
