How do you build Cisco networks in GNS3? In this video I show you how to download Cisco IOS images (Cisco VIRL images) to run IOSv and IOSvL2 in your GNS3 topologies. I also show you how to add Docker containers to your network.
Cisco VIRL has fantastic images which you can download such as:
- Cisco ASAv - Virtual Cisco ASA Firewall
- Cisco IOSv - Virtual Cisco Router
- Cisco IOSvL2 - Virtual Cisco Layer 2 and Layer 3 Switch (multilayer virtual switch)
- Cisco NX-OSv - Virtual Cisco Nexus Device
- And even more cool devices.

Hi David Thanks for your great demos ! What's the relationship/difference between VIRL and EVE-NG ? I tried to install VIRL and GNS3 but never was able to make them work. I could draw a topology but always got some weird message when I tried to configure the devices, and I never could find anyone who could help me. None of colleagues or former colleague know of either of the tools. Now I have a brand new laptop with i7 processor and 32GB of RAM. Which solution (VIRL vs GNS3 vs EVE-NG) would you recommend me to install ? Thanks Dany

@bootitwill Год назад

great video, but I find it baffling that all this training crap from cisco: tests, books, images, labs, is all requiring a purchase. that I have to purchase a virtual router or switch from cisco to train and learn their stuff so my company can purchase and buy more real crap, is borderline antagonistic. cisco's nickel and diming mentality is going to be their downfall. in fact, its already starting. resting on your big customer base will only get you so far. eventually that base will erode. if I'm mistaken, someone advise how i can get free virtual image of basic cisco appliances. im not going to try to rip off cisco by running a huge workload in VMware player on my 8GB laptop!
