The reason you're not getting an answer isn't because we're blowing you off. It's because it's too complicated for an easy answer. You'd have to talk to the IOS developers for a good answer. I have a training manual that was used to teach new IOS developers. I checked it. Although it talks a lot about memory management, it doesn't mention how much memory each route takes. For one thing, it would certainly depend on the routing protocol. EIGRP's scaled, composite metric takes more bytes than RIP's hop count, for example, although from what I learned about memory management from the developer training, memory is managed in chunks, so a few bytes probably wouldn't matter. Most of the routing protocols save more info than just the routing table. OSPF and EIGRP have a topology database, for example. So that would definitley affect memory usage. Also, unless you plan to save all of the Internet BGP routing table, it's simply not an issue. Routers have enough memory to store routing tables in most cases... So, it's not a very relevant operational questions?? If it's a research project, well get researching. Asking us won't help, I'm afraid. :-) Priscilla > > Hello folks, > > I have to evaluate the impact of adding almost 1000 routes in > my network, and what I want to know is simple: How many memory > do I need for every new router?
