I am thinking about sitting the CCNA this year, and want to get as much exposure to routers as possible. I have 3600 series and 800 series at work but as these are 'live' I can't really mess around with them too much!! I am looking at router simulation s/w as a possible alternative and would appreciate any views on the from people who have used them (ideally for the same purpose as I want to). Or does anyone know of any good cheap routers (2500 series) for sale or web sites etc that sell second-hand ones.<br>Thanks
