Hi David: I was dreading dipping into GNS3. You made the process painless and fast. I learned what I needed in a couple of hours rather than days. The best thing about all your videos is that everything WORKS just the way you show it. Great work.

The best thing about David is, he cuts the marketing fluff/jargon's and focus on the logic/concept. Well done, David..

Awesome video David. Whenever I run into a problem, your channel is the first place I look for answers, and almost everytime I tend to find what I'm looking for..

Thanks David. I was able to buy Cisco license, download my images and configure them in GNS3 successfully following your step-by-step. Feels good to have the original images :)

Am always overwhelmed by your work to the extent that I lack the words to describe you and your knowledge and skills. Great Gem.

Fantastic video David!! Great to see what GNS3 is all about with your practical example.

I coughed up the $200 bucks for the Cisco Virl access. It was another learning experience figuring out how to use them. After getting error messages. I came back to this video and it saved the day once again. Thanks

Thank you very much. I am working on transitioning from live equipment and Packet Tracer. I was able to follow the steps and get everything set up. Looking forward to build off what I learned today. Thanks again.

Thank you David. I now have GNS3 successfully installed and functioning with Cisco VIRL.

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

I love Davids content, its the most detailed content and with step by step instructions. thanks lots David , continue the good Works!

@David Bombal Once you you purchase VIRL do you have to keep renewing it every year to use the images on GNS3 or EVE NG?

hi Mr David, i followed all these steps, got my gns up and running, i've got 1 issue, my router doesnt support show vlan brief, but the switch does, what can i do? or is there another router ios i should buy?

Loved your work man, Keep it rolling :)

Thanks David, it is pretty good intro. A question: Is there any limitation in comparison of physical switch/router to VIRIL IOS images ? (such as some commands wont work)

Slowly transitioning to GNS3 vs Packet Tracer. Thank you for the intuitive tutorial 👍

@David Bombal, is this VIRL enough to get my CCNP ENCOR?

Hello David!! Is Cisco still offering this option to download vIOS for our use on GNS3, or does the $199 only get us use of the Cisco online virl labs? Thanks!

Hi David, Once my subscription ends, will I still be able to access and download Cisco Modeling Labs or do I have to purchase to access the modeling labs from Cisco.

Excellent video I built my GNS3 LAB successfully thanks you very much David.

doubt, can we Move the IOS images from the downloads folder after we successfully imported to GNs3vm or GUI, ? or it should be stay in the same location.

Great job, thank you for your videos, I'm trying to deploy a network with docker, gns3 for testing IPv6 and Suricata, I'm have a lot of question, but your videos answer many of these. thanks again.

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!

Hi I am running linux (latest ubuntu) and from what I read I can run this without a vm? I am prepared to buy virl for the images for use in gns3. my question is can I use the images after a year? do the images go dead or just virl? I don't plan on using virl just the images in gns3. thanks.

Sorry for the novice question, can you only have cisco devices or are there other branded devices ie: Netgear dell, etc

I've partially completed the GNS3 set up. Struggling to finish it. Need assistance. Anyone?

Hello. I don't know if Cisco creates problems if someone downloads the images, by paying for them, without the program concerning CCNA or other certifications. I mean cancel or do not allow to participate in future exams. Can anybody help?

If you mean serial interfaces, they are not supported on VIRL images. You would need to use a 7200 image like I showed in this video: kzread.info/dash/bejne/eXZmrcpwc7mWmpc.html However, Cisco are removing WAN technologies from the CCNA exam, so I think Ethernet will be enough for most of us moving forward.
