[j-nsp] MPLS EXP bit marking question

[Li Zhu]

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
