One possibility would be to manually set the MPLS exp bit on your
RSVP tunnel under edit protocols mpls label-switched-path. This
overrides the CoS setting for rewrite (but not the scheduler
config). If you are using LDP, you use the set protocols mpls
interface <name> label-map <label-val> command. Note that this is a
crude method and not exactly what you are probably looking for.

Subject: Re: [j-nsp] MPLS EXP bit marking question
Masood, Nugroho
Thank you for the reply. I agree with both of you that rewrite takes
effect
on both inner and outer mpls label. My next question is:
what if I want to mark inner and outer MPLS label differently? Say I
want
mark the inner exp with 5 and outer exp with 6? Is it possible to
achieve
this?
Thanks,
Li

All,
There is a network like CE --- PE --- P. The PE is M320. Traffic is
from
CE
to P. The traffic out of CE is native IP, after it reaches and gets
out
PE
(then to P), it is double-tagged with MPLS lable. There is a exp
rewrite-rule applied on PE link to P router. My questions is
will the rewrite-rule take effect on both tags or only the outer
tag?
Thanks,
Li
