I would tend to keep the filters on the edge, for obvious reasons. Your 
management would probably agree with this the first time you get attacked 
coming from each of your edge routers with nothing to protect it from 
happening. 

You could always make a script (PERL) to go out and make the modifications 
to your edge routers for you.

My $.02,
Mike
