Iosv Gns3

It is possible to extract IOSv (IOS 15.4) from Cisco's onePK SDK 1.3.0 (with a devnet account) using Qemu or VirtualBox and run this image inside GNS3 through a Qemu or VirtualBox guest. Some clear advices on linux are available here, by Radovan Brezula or my own advices. Jul 14, 2014 GNS3 is an open source (GNU GPL) software that simulates complex networks while being as close as possible from the way real networks perform, all of this without having dedicated network hardware such as routers and switches. Jul 21, 2019 The tutorial discuss the use of GNS3 software to run Cisco Virtual IOS (vIOS). Cisco vIOS is shipped and supported as a part of the Cisco's One Platform Kit (onePK) that is distributed in form of virtual machine. It might be downloaded with Cisco.com account.

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.

Iosv Gns3 Version

To use GNS3 as a networking lab, you will need to supply your own router, switch and firewall images. The easiest way I’ve found to do this is to subscribe to Cisco VIRL (Virtual Internet Routing Lab).

VIRL allows you to download the following up-to-date images directly from Cisco:

  • IOSv and IOSvL2
  • NX-OSv and NX-OS 9000v
  • IOS XRv and IOS XRv 9000
  • IOS XE (CSR1000v)
  • ASAv

Since I am doing this on my Macbook, this guide will be for MacOS. However, the process is similar to Windows.

Iosv Gns3 Download

Gns3 iosv l2

Required software:

  • VMWare Fusion $79.99 – (I used my Alumni account to get it free from my university) https://www.vmware.com/products/fusion.html
  • VIRL $199 – https://learningnetworkstore.cisco.com/cisco-virtual-internet-routing-lab/personal-edition-virl-pe-20-nodes-virl-20
  • GNS3 App $FREE – https://www.gns3.com/software
  • GNS3 VM $FREE – (You have to use the additional VM for QEMU images) https://www.gns3.com/software
  1. Install VMWare Fusion and follow the prompts for a default install
  2. Open Fusion and the virtual machine library
  3. Click the plus symbol at the top and click import
  4. Click Choose file and navigate to the GNS3 VM.ova, click Continue
  5. Click Save
  6. After it finishes importing, click customize settings
    1. Under processors and memory, set Processors and Memory to what you need – I am using 2 Processors / 4GB memory. Click advanced settings and check enable hypervisor applications in this virtual machine.
    1. No other changes are required, but customize this as you see fit
  7. Start the VM
  1. Install the GNS3 application and open it
  2. On first start, it should open a configuration wizard to configure the local server and GNS3 VM. I have already completed this step, so I have included screenshots of my GNS3 > Preferences menu instead:
  3. Open a new project
  4. Take note of the Servers Summary on the right-hand side that displays your PC and VM CPU and memory. Keeping an eye on your CPU and Memory will stop you from creating too many devices in your deployment.

Import appliances into GNS3

Think of appliances in GNS3 as routers and switches. To import an appliance, you’ll need:

  • Appliance file
  • Router/Switch/Firewall image
  • For routers you will need a startup config
  1. Go to the GNS3 docs page, find the IOSv doc, and look at the supported versions for the appliance. The docs list every file you need to use an appliance.
  2. Download the IOSv image from the VIRL webpage of the supported image you’re using
  3. Download the appliance file from the GNS3 marketplace
  4. Repeat steps 1-3 for EACH appliance you will be importing (IOSv, IOSvL2, and AVAv)
    1. Routers require the startup config file that can be found on its doc page
  5. In the GNS3 app, Click File > Import Appliance
  6. Browse to where you saved the cisco-IOSv.gns3a appliance file and click open
  7. Click Next
  8. Click Next
  9. You will be greeted with an overwhelming required files screen. You will need to import the images you downloaded earlier into the template here
  10. Click on the image that you downloaded from VIRL and click import
  11. Navigate to the image and click open
  12. Repeat this step for the IOSv_startup_config.img you downloaded from the docs page
  13. You should be here:
  14. Click Next
  15. Click Finish
  16. You should see your appliance under browse all devices
