[j-nsp] MPLS EXP bit marking question

[Christian Martin]

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.
