jason,

why do you want to export a labeled route to a protocol that does not
support the notion of labels ?

IMO there are two solutions paths:

1. if you don't care at all about labels then you should install your
   routes into inet.0 right away [i suspect that you do install your labeled
   routes into inet.3]

2. if you do care about labels then leave it into inet.3 and
   add to any of your ospf export policies the 'from rib inet.3' clause.
