it's pretty easy to inadvertently leak a copy of the internet from one 
vrf to another and effectively install two copies of the internet routes 
in your fib...

There are plently of cases where you might to that or something similar 
on purpose, which is all good and
 well if you have 2million route fib capacity but less awesome if you 
have 512K route capacity linecards at this point. if you get those 
routes from a private peer on some non-internet-vrf well that might 
imply that your filter policy needs some tuning.
