We're debating that.. I'm not the guy who designed this, but that's the 
long-term goal.  ;)

Right now, we're filtering /24's to get by temporarily (with default 
routes to cover), which after doing a 'clear ip route' on the Cat's, gave 

Dec  3 11:49:02: %MLSCEF-SP-7-END_FIB_EXCEPTION: FIB TCAM exception cleared, all CEF entries will be hardware switched

..and the problem cleared up.

We'll be looking at re-architecting some of this shortly, but this should 
get us by for now.

Thanks for the replies!
