    Your first point makes sense, your second point is how stupid the voting system has become on this site, if it is the case.

    They're easy to get, just search for them. If Cisco care then they don't … They're easy to get, just search for them. If Cisco care then they don't deserve your business.




    I don't think this si the way that copyright law works. If you are going for the CCNA, you might also want to check the agreement you are signing

    you forgot to add that you need the firmwares which you cannot get legally without owning a physical device or a cisco subscription.

    I think you need copies of the IOS software to get labs fully working - correct me if I'm wrong

    This is a really good point - without the IOS software, you could set up some elaborate diagrams, but no testing.

    Hahaha, have you got the rulebook printed off and laminated? Can you … Hahaha, have you got the rulebook printed off and laminated? Can you quote chapters and sections from it? People like you are a problem, you allow corporate bullies to get away with running the world.Use Juniper in GNS3 if you're too much of a goody two shoes to obtain IOS images. Juniper offer a free image because they're not as greedy as Cisco (their kit is better too). There's other free images you can use, try Vyatta/VyOS, DD-WRT, Quagga in Linux etc.It may not be how "copyright" law works but it's certainly how a free market works, you don't keep up, you don't do as well or better than your competition, you lose



    indeed haha. You invest a couple of months of work in getting certified just to get it void by using GNS3 without licenses. Good job
