Don’t get hung up too much on the interface. Select a NOS that has the networking function you’re trying to learn from whichever vendor. Remember–configuration is the boring part. I haven’t worked with Cumulus in production, although it’s been a passive interest for a while now. JUNOS, too, although I don’t have a Juniper virtual device on this list currently. I’ve worked with both EOS and NX-OS in production environments.
I have no personal allegiance to any of these operating systems. The list is vendor-neutral, sorted alphabetically. Use those same channels if you just want to tell me I’m wrong about whatever you come across in this post that’s…you know…wrong. Make sure your recommendations are for images which are freely available from the vendor for lab use with no licensing requirements or other strings attached. Let me know on the Packet Pushers Slack channel or Twitter DM, and I’ll do additional posts or update this list over time. My goal is to clearly document what these images are and how to obtain them, as this data is less obvious than I’d like. Or if you have a server, download the CML on the server and make sure the server is able to handle it.Here’s my current list of no cost, minimal headache, easily obtainable networking images that work in a virtual lab environment such as EVE-NG or GNS3. The only think you need to think about is you need a solid computer with x amount of RAM (the more nodes, the more RAM and storage is required) and storage. You can download bunch of stuff, like Nexus, Fortigate, ASA, routers, switches, servers and so on. You can even download the images and use it offline so it is not that you need to pay $199 every year. You can purchase CML from Cisco website and it will cost you $199/year and I will highly recommend you to invest in it. You also have EVE-NG (which is not Cisco) and I personally have not used it but it’s looks much nicer than GNS3. What I (and most of the people) recommend is Ciscos own virtual lab, CML (Cisco Modeling Lab) that is equivalent to GNS3 but a little bit better.
There are free IOS images but would not recommend you to download those.
