By default it will drop the traffic.  If you know the incoming label  
you can create a static binding, but you can't create a static binding  
for the default route... Not sure of any other mechanisms.

In JunOS you can create an "MPLS default route" which takes unknown  
labeled packets and lets you manipulate them as you see fit.  But this  
isn't JunOS. :)
