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.
2 hours deep and now I need 200 to continue? So disappointed, not your fault.. thanks for the videos up to this point... a shame I can't continue. I'm a programmer analyst now working from home attempting to learn networking to help an IT department out. I'll have to find a different way now...
He should have used an alternative that is similar to GNS3 and is free or open source , but money talks mate. He get paid to make these videos, sorry to hear that he wasted your time. I will recommand you CISCO packet tracer or Virtual PC Simulator.
@@secondsight2091 I do get those for me mate, there is a CZcamsr that shares his resources. However, he should have mentioned that at the beginning of the course, not everyone once to download files from random websites.
@@dan-simi6 Oh I see what you're saying. He said that at the beginning in a previous GNS3 video he made. I think he was just assuming everyone will have already watched it as it was the very first vid in his playlist. Which youtuber are you talking about? netchuck?
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
David Bombal Your just start and learn as you go is a great Motto. I found that you learn so much more than what you set out to learn by the time you’ve learned it.
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 :)
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..
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!
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.
Great video, thanks it really help me set my lab for your python class, BTW for all others make sure you are off your VPN if you want the VM to connect, this keep me awake for a thinking for a bit
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.
Can you make a tutorial on how to set up the GNS3 Server? you showed how to get it to run on your personal pc, then in the next GNS3 video tutorial, you are in a server instead of running it locally. Would greatly help as there seem to be hundreds of ways to run the server (Ie) Microsoft Azure or Vmware.
is this still valid? when I travel to the virl site it now takes me to a product called "Cisco Modeling Labs - Personal" which seems to be similar, but not sure if it will allow downloading of the images.
Thank you for everything. You have been a huge help to me!!!! I came across an issue and I would like your input. After following this video I have an issue pinging my loopbacks and R2. I'm not sure if it's a glitch in the matrix or not. I was able to ping R2 at one point. What would you suggest? VLANS,or SVI?? I bounced all loopbacks and SVI and completed the basic troubleshooting.
Thank you very much Mr. David. Can you please make an other video about How to share or co-collaborate the GNS3 VM whit your friends over the Internet securely? I have a powerful PC (Ryzen 7 2nd Gen, 16 GB of RAM) and I want to practice and share projects whit my friends and see their practices and changes in real time, my friends in other had don't have a powerful PC, I want them to install the GNS3 Client and then point to my PC over the internet securely so they can reach the GNS3 VM that it is installed on my Computer. Is basically the same implementation of Cloud Computing video of Network Chuck, @Tvrs in his video he shows how to install GNS3 whit Microsoft Azure. But for economics reasons, especially to reduce cost or don't have the money 💰 to buy Microsoft Azure or Amazon AWS or any other Cloud Computing Solution, it will be very nice to share your Computer, Network Projects and Topology whit your friends, so they can Connect to a Cisco Router or Switch using SSH over the internet securely. At least so we can practice Routing Protocols and Switching Configurations together this of course is for lab and practice environment only and to be clear I bought the Cisco VIRL imagines. Can you imagine that dose devices are actually virtualize? 😮 that is amazing! how far the technology have evolved 🤩😎! Anyways back to the subject, It will be illegal to do this? Waiting for your reply and for the community Regards Ran Shemer from Dominican Republic, a huge fan of yours! Blessings to you and your Family Mr. David Have and nice day.
Thank you Ran! Appreciate the support. Technically you should have no issue doing what you suggest. At the moment because GNS3 doesn't have a full Web User Interface, each person will need to have a VPN connection to the VM so their clients can connect to the GNS3 VM. Legally, you will need to talk to a lawyer as I am not able to give legal advice.
Hi David, I really enjoyed your videos a lot, a big thank you. I have one question though. After I created the network topology, how can I access the network outside GNS3 GUI ? Like I wish to run a network monitoring software on host machine to monitor the router\switch\VPCS inside the GNS3 network topology. Thanks.

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
Hi david , Thank you for your helpful instructions , I have a laptop purely running Ubuntu 18.04 LTS , I have installed GNS3 on my Ubuntu machine , Do I still need to install the VM for iOS images that you talk about earlier in your Video seeing GNS3 is already built around Ubuntu OS?
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)
Thanks for the tutorial, I had some difficulties and this video helped me out a lot. Question. Why are you running a Mac with Windows 10 in a virtual machine, and GNS3 in the Windows environment. Why not run GNS3 on your Mac?
I am controlling the Windows laptop running Windows 10 from my Mac using VNC. I am not running Windows in a VM in this example - it is installed natively on that laptop in the background on my desk. I will demonstrate GNS3 on a Mac in a separate video.
Thank you for the videos. it was eating as one eating chicken. but i got a question. Please how do i change the routers starting number from zero to ones.
Thank you very helpful. I have just a question if i can use python with this lab and docker without importing it as you do it in your past demonstration.
Depends on what you want to do. I have demonstrated on box Python in previous videos. You could also just bridge your local computer to your GNS3 topology if you wanted to.
Awesome video David. I am running GNS3 on Ubuntu20.04. Do you have a video on installing and running the IOSv in GNS3 running on Linux? Do I still need to run the GNS3 VM? Do I need the KVM/QEMU installed on my Ubuntu PC? any help would be awesome. Thank you again. Brian
Sir I have an doubt.?? Basically GNS3 need a VM for running another network devices but if I install a Ubuntu so still I need to follow the GNS3 Virtual machine installation because I have read a lot of articles but they have mentioned that GNS3 does not required VM when you are using a linux system. So can you resolve my quiery
Thank you David! One question: If I buy a Cisco VIRL license for 1 year and I download Cisco images to use them in GNS3 & EVE-NG, and then after 1 year my VIRL license expires, Would the Cisco images still work after my VIRL license expires? Will I be able to use them after my VIRL license expires after one year? Thanks!
Yes. If you have a switch or router image / .bin file then be sure to use the Dynamips setting in GNS3 (Edit > Preferences > look for Dynamips on left hand side. You can upload a new image from there. Good luck.
I started in IT in my early twenties. I will create video of my career, but this video gives you an idea of how I got started: czcams.com/video/DQR5EqM1doQ/video.html - I have definitely had lots of ups and downs over the years.
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: czcams.com/video/GB2Kh7CV0j4/video.html However, Cisco are removing WAN technologies from the CCNA exam, so I think Ethernet will be enough for most of us moving forward.
Hello, I have a question about whether I can emulate gigabit ethernet (throughput 1000 Mbit/s) with this Cisco IOS in GNS3 without limit? I'm going to buy these products. I need to emulate gigabit throughput. Thank you for your answer!
Hello David Sir, I really enjoyed this video and I appreciate your efforts to teach us..However, I would like to know is there any difference between VPCS & Docker container. Can't we use VPCS instead docker container?
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.
Hi, Master! I installed the new GNS3 GUI and GNS3 VM 2.2 from scratch but I had a problem opening the “GNS3 VM.ova” which I fortunately managed to solve. That's why I wanted to share with you, my issue and also the solution, which could be useful to someone else. The issue ======== After upgrading the VMware Workstation Pro 12 version to Pro 15.5 and unzipping the “GNS3 VM.zip”, opening the file "GNS3 VM.ova" showed me the following error message: "Failed to read from file: GNS3 VM.ova" I downloaded the GNS3 VM again 5 times, both from gns3.com and from github. I also unzipped the "GNS3 VM.zip" with several different softwares (7zip, winRAR and the native Windows) but i still had the same problem: -> "Failed to read from file: GNS3 VM.ova" The workaround ============= 1) Rename "GNS3 VM.ova" to "GNS3VM.ova" 2) Extract the OVA on a linux system by running the command: # tar -xvf GNS3VM.ova -> you will get the OVF and VMDKs as separate files: GNS3 VM.mf GNS3 VM.ovf GNS3_VM-disk1.vmdk GNS3_VM-disk2.vmdk (If you want to run a Linux shell system without VMs or emulations, integrated directly with Win 10 and consuming few resources, you could use the magical Microsoft WSL (Windows Subsystem for Linux), version 1. It's free and downloadable directly from Microsoft docs.microsoft.com/en-us/windows/wsl/install-win10 I have installed many real Linux shell distros like Debian, Ubuntu, Fedora, Kali, Alpine and OpenSuse, even with Python 3 virtual environments running like a charm!) 3) Move the files to your Win 10 system. (No needed if you used WSL.) 4) With VMware Pro 15.5 just open the OVF file GNS3 VM.ovf -> and that's it!!! The GNS3 VM was sucessfuly imported and now is working. My implementation of your GNS3 2.2 Install lab ======================================= After my issue, I Installed and configured IOSv, IOSvL2, IOS-XE (CSR1000v), IOS-XRv, NX-OS and some Linux docker containers -> All of them are working together really really well. (I set the GNS3 VM to 12GB RAM, 2 vcpu) It was worth the wait for this new version of GNS3!!!!! Thanks again David!!!!!
Thank you for sharing! I didn't have this image, but hopefully your detailed comment will help others who encounter the same issue as you did. Thank you for explaining so clearly what you did :)
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.
Hi David - I have downloaded GNS3 V2.2.10 with VMware Fusion on my Mac. I keep getting c3725-adventerprisek9-mz.124-15.T14.image" is not a valid IOS image whenever I try to fire up a router (7200)...Any ideas or can you point me to a tutorial. It appears a lot of your tutorial are WIN10. Great work by the way, really appreciate it..!!
Mr. Bombal, thank you for those educatives videos. I have a question for you, but I dont know if this is the rigth place to ask. Do you have some blog page I can ask you about? thank you.
@@davidbombal Thank you in advance. I used GNS3 VM in ESXi 6.5 so, where do I change the VM config? in the VM or GNS3 application? I mean, add memory and CPU.
Thank you. No - only certain images are supported in GNS3 like 3600 or 3700 router images. Best option today is to use VIRL images or Cisco CSR images.
Hi can you please tell me how to active virtualized intel vt-x/EPT on lenovo thinkbook 20VD I have activated but still ask me to activated it when I run vmware workstion thanks in advance
there is an Error while inserting a router or switch in topology which is " Error while creating node from template: The image IOSv-L3.qcow2 is missing "
Hey David the QEMU steps explained here applicable to virtualbox as well. I can't seem to get it working on Virtualbox tho. I get an error "The selected server does not support KVM........." I have enabled extended features such as PAE/NX and Nested VT-x/AMD-V
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?
Hi Sir, thanks for the great video. Actually I am one of your CCNA student and still studying to take the exam. Also I am taking your course Linux for Networking engineer at Udemy and I just got a problem with dowloading Cisco IOS images. Please advise If there any other way to avoid $199 ?
First of all, great video David! I do have a question though. I've purchased VIRL PE and tried to use the images in GNS3. But both IOSv and IOSvL2 nodes boot with high CPU issues. Any idea on how to fix this?
@@davidbombal Thanks for reaching out so quick! Is this also the case with VIRL 2? And increasing the cpu's and/or ram on the nodes themselves doesn't help?
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!
I bought virl. downloaded the images and am running into an error. QEMU process has stopped, return code: -6. Any clue what this errors mean. Can't seem to find anything online.
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?

Does cisco virl allow us to habe images to practise wan configurations on gns3? The router IOSv seems to only have gigabit interfaves
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: czcams.com/video/GB2Kh7CV0j4/video.html However, Cisco are removing WAN technologies from the CCNA exam, so I think Ethernet will be enough for most of us moving forward.
you are great teacher
thanks
Thank you Uraj
Awesome as always.
Thank you Precious!
thank you very much
Hello, I have a question about whether I can emulate gigabit ethernet (throughput 1000 Mbit/s) with this Cisco IOS in GNS3 without limit? I'm going to buy these products. I need to emulate gigabit throughput. Thank you for your answer!
Hello David Sir,
I really enjoyed this video and I appreciate your efforts to teach us..However, I would like to know is there any difference between VPCS & Docker container. Can't we use VPCS instead docker container?

I wanted to buy it, but now I can't find it. It seems like is not available.
Does Huawei offer images for GNS3 for their routers and switches etc... such as cisco ??
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.
Hi, Master! I installed the new GNS3 GUI and GNS3 VM 2.2 from scratch but I had a problem opening the “GNS3 VM.ova” which I fortunately managed to solve. That's why I wanted to share with you, my issue and also the solution, which could be useful to someone else.
The issue
========
After upgrading the VMware Workstation Pro 12 version to Pro 15.5 and unzipping the “GNS3 VM.zip”, opening the file "GNS3 VM.ova" showed me the following error message:
"Failed to read from file: GNS3 VM.ova"
I downloaded the GNS3 VM again 5 times, both from gns3.com and from github. I also unzipped the "GNS3 VM.zip" with several different softwares (7zip, winRAR and the native Windows) but i still had the same problem:
-> "Failed to read from file: GNS3 VM.ova"
The workaround
=============
1) Rename "GNS3 VM.ova" to "GNS3VM.ova"
2) Extract the OVA on a linux system by running the command:
# tar -xvf GNS3VM.ova
-> you will get the OVF and VMDKs as separate files:
GNS3 VM.mf
GNS3 VM.ovf
GNS3_VM-disk1.vmdk
GNS3_VM-disk2.vmdk
(If you want to run a Linux shell system without VMs or emulations, integrated directly with Win 10 and consuming few resources, you could use the magical Microsoft WSL (Windows Subsystem for Linux), version 1. It's free and downloadable directly from Microsoft docs.microsoft.com/en-us/windows/wsl/install-win10
I have installed many real Linux shell distros like Debian, Ubuntu, Fedora, Kali, Alpine and OpenSuse, even with Python 3 virtual environments running like a charm!)
3) Move the files to your Win 10 system.
(No needed if you used WSL.)
4) With VMware Pro 15.5 just open the OVF file
GNS3 VM.ovf
-> and that's it!!! The GNS3 VM was sucessfuly imported and now is working.
My implementation of your GNS3 2.2 Install lab
=======================================
After my issue, I Installed and configured IOSv, IOSvL2, IOS-XE (CSR1000v), IOS-XRv, NX-OS and some Linux docker containers
-> All of them are working together really really well. (I set the GNS3 VM to 12GB RAM, 2 vcpu)
It was worth the wait for this new version of GNS3!!!!!
Thanks again David!!!!!
Thank you for sharing! I didn't have this image, but hopefully your detailed comment will help others who encounter the same issue as you did. Thank you for explaining so clearly what you did :)
Thank you ❤❤
Good morning
The only problem with my GNS3 is my KVM does not support images. please what to do to fix this.
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.
Thank you very much, btw, nice intro music. What is that song's name?
Hi David - I have downloaded GNS3 V2.2.10 with VMware Fusion on my Mac. I keep getting c3725-adventerprisek9-mz.124-15.T14.image" is not a valid IOS image whenever I try to fire up a router (7200)...Any ideas or can you point me to a tutorial. It appears a lot of your tutorial are WIN10. Great work by the way, really appreciate it..!!
What kind of chair are you using in the video please?
Thanks!
THANK YOU.
Thanks David for your work!
As usual, it's impressive.
A question:
Are you going to explain how to migrate properly from gns3 version 2.1.. to 2.2.1?
Thank you. Yes, this is on my list.
Mr. Bombal, thank you for those educatives videos. I have a question for you, but I dont know if this is the rigth place to ask. Do you have some blog page I can ask you about? thank you.
You can ask here.
@@davidbombal Thank you in advance. I used GNS3 VM in ESXi 6.5 so, where do I change the VM config? in the VM or GNS3 application? I mean, add memory and CPU.
that's great video !!!
Question, how I can upload real IOS .bin to GNS3? for instance for the current routers ASR and ISR. thanks.
Thank you. No - only certain images are supported in GNS3 like 3600 or 3700 router images. Best option today is to use VIRL images or Cisco CSR images.
Thnk you
Thank you for watching Omar
Hi can you please tell me how to active virtualized intel vt-x/EPT on lenovo thinkbook 20VD I have activated but still ask me to activated it when I run vmware workstion thanks in advance
there is an Error while inserting a router or switch in topology which is " Error while creating node from template: The image IOSv-L3.qcow2 is missing "
Hey David the QEMU steps explained here applicable to virtualbox as well. I can't seem to get it working on Virtualbox tho. I get an error "The selected server does not support KVM........." I have enabled extended features such as PAE/NX and Nested VT-x/AMD-V
Quick update: the new beta version 6.1.0 has the option to enable this bit.
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?
hello Mr. David,
Which is the best cisco ios to use for practice when you're planning to get a CCNP?
I suggest you get Cisco VIRL image IOSvL2 for switching and IOSv for routing. I show you in this video how to download those images.
Hi Sir, thanks for the great video. Actually I am one of your CCNA student and still studying to take the exam. Also I am taking your course Linux for Networking engineer at Udemy and I just got a problem with dowloading Cisco IOS images. Please advise If there any other way to avoid $199 ?
First of all, great video David!
I do have a question though. I've purchased VIRL PE and tried to use the images in GNS3. But both IOSv and IOSvL2 nodes boot with high CPU issues. Any idea on how to fix this?
You need to wait until things settle down. This is however an issue not just with GNS3, but also on other platforms like VIRL and EVE-NG
@@davidbombal Thanks for reaching out so quick! Is this also the case with VIRL 2? And increasing the cpu's and/or ram on the nodes themselves doesn't help?
3:55 Show us SHA-1/MD5/SHA-256 checksums, that's enough :DD
Do you need a "business" email to download these images from the Cisco Learning Network?
Sorry for the novice question, can you only have cisco devices or are there other branded devices ie: Netgear dell, etc
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!
I bought virl. downloaded the images and am running into an error. QEMU process has stopped, return code: -6. Any clue what this errors mean. Can't seem to find anything online.
Nevermind. Found a fix. github.com/GNS3/gns3-vm/issues/130
i am running into the same thing.
