GNS3 for CCNA
So my budget for a lab is about 0$ and I'd like to get my CCENT then CCNA and hopefully that will lead to a budget that's not 0. To stay in budget I have elected to use GNS3 for my labbing needs. My question is will this be enough? And what router should I use? I have C7200 ADVENTERPRISE-K9 15.2(4)S3 and was curious if that will be enough?
