  • What IOS Version on Cisco 2520 Router

    I'm thinking of using Cisco 2520 routers to build up a CCNA home lab. Can anyone give me any idea what IOS version a used 2520 would be likely to have on it. I figure used C2955-12 would likely be version 12.X?? Any other thoughts on building a Cisco lab are welcome also. Thanks to all.
