We added memory where we could, or bought bigger routers. The new (conventional wisdom) limit is 1M routes.
I think you mean 512k IPv4 with 256k of IPv6 (taking double space).
if you're still on a platform with 40Mbit cams it's beginning look kinda tight as an internet router. you've probably got less than a year to figure out what to do about this. an f10 ej linecard cam paritioning scheme for example looks something like.

Make sure you check your tcam profiles :)
