Well, the more routing entries you have, the more memory you 
need to hold them.

This is truer for dynamic routing protocols than the 
opposite, as routing entries learned dynamically carry 
additional attributes along with them and all sorts of 
goodies that need to make friends with RAM + CPU :-).

1,000 static routing entries should not be a problem for the 
platform to handle. I'd be more worried about your energy 
levels and the amount of NVRAM at your disposal (although 
there are other options you can consider to manage a larger 
active configuration).

Cheers,

Mark.
