Does anyone know what type of routers you need for the new CCNA 802 home lab. I have two 1720s and I dont have a lot of money to spend right now. I also have the Routersim Network visualizor 5.0 for the 801. Can I get another 1720 and maybe a switch. Will that be enough. I mean I'd love to have more but I can't afford it now. Any suggestions?
