RE: Choosing the right IOS Image [7:739]
Roger, I ran into the same problem you had. You want to run enterprise images with all the bells and whistles and be 12.0 ver. The only wy was for me to up grade all of my routers to 16 meg flash. Yes a bit costly but in the end to be able to get things done well in a home lab is to have an IOS that have the multifuntionality that will be found on those routers which you will be tested on. The 11.1 enterprise image will run on 8 megs of flash. also the enterprise plus in 11.2 will also run on 8 megs of flash.

I remember hearing from Louie that he ran 12.09 Enterprise Plus IOS on all of his 2500's with that 16/8 configuration. There's a 12.7 version but it won't fit on only 8MB of flash space. Does this mean that I should I consider upgrading to 16MB flash instead? On another note, can anyone recommend a good reference for knowing which type of IOS images to use? Like how I can assess whether I would want to use a Service Provider image rather than an Enterprise image, or an IP Image, or maybe even an Enterprise/FW/IDS IPSEC image. I'm trying to find out more information on what requirements would prompt me to choose one over the other. I've only been able to find a few docs on CCO and they haven't helped me much. Any info is always appreciated!

Re: Choosing the right IOS Image [7:739]
With 8MB of Flash, I would recommend you to ran IOS version 12.0(15), IP/IPX/AT/DEC. This is the latest version of v12.0. It's only require 8MB of flash and is a clean version (have the TCP security flaw bug fixed).

Re: Choosing the right IOS Image [7:739]
Hi; As a matter of fact, Cisco 2500 is not compress image. You have to use compress tool like mzmaker to compress cisco ios image. The size of the IOS image is much more smaller and it will fit 8M flash. Be careful, you need to have enough memrory in your router. Becasue the IOS will self-decompress the IOS while start up. It has no problem on cisco 2501, 2513, 2521. I strong recommend that you should not use "mzmaker" in production environment. You should try to serarch in the cisco website, type cross platform .. For example, memeory requirement for 12.1 for various platform that you can follow the link that http://www.cisco.com/univercd/cc/td/doc/product/software/ios121/121relnt/xpr n121/121feats.htm Hope this help Vincent Chong ""Roger Sohn"" Hi All, > > Just wanted to hear what other people are using (or would recommend) for the > IOS images on their 2500 series routers with a typical 16MB DRAM/ 8MB Flash > setup. > > I remember hearing from Louie that he ran 12.09 Enterprise Plus IOS on all > of his 2500's with that 16/8 configuration.
