The easy answer is as much as you can! You may be able to get away with a minium of 120M. Thats cutting it close.

It depends on how many routing tables you intend to keep and how many neighbors you have that will be sending you full routes.

Remember, each interface will keep a full routing table in memory until they are all processed. A good estimate would be around
