In this post, we are going to deploy an IOS-XRv VirtualBox Image (a free demo image) in GNS3.
The recommended Cisco images to use with GNS3 are those from Cisco VIRL (IOSv, IOSvL2, IOS-XRv, ASAv). This images are supported and are actively updated by Cisco. The images support current releases of the Cisco IOS (15.X) and provide the best scale and user experience. Download Cisco ASA IOS Image For GNS3 and EVE NG Free Download Cisco IOS Images for GNS3 and EVE NG First file (hda.qcow2) and fifth file (nxosv-final.7.0.3.I7.3.qcow2) of the below list is 100% working and tesed on eve-ng platform by us, before uploaded here, Other files should also be good of below list. From Cisco perspective we are not allowed to use image on GNS3. There is no demo of IOS. No official word from Cisco regarding using image in gns3. Some users argue that u could use image from real device u owned; I think this might be a grey area; what about GNS forum or gns3 people, do they mention anything about getting images? Cisco-ios-image-for-gns3.md Download FREE Cisco IOS image for GNS3 Hi dear all, that’s really a great to share my hard work with you, After a lots of hit in Google I finally found trick to search Cisco IOS in free of course.
First of all, we have to download an IOS-XRv VirtualBox Image on Cisco upload page. In this lab, we use IOS XRv 612 (iosxrv-k9-demo-6.1.2.ova).
Bear in mind that we need a Cisco CCO account to download the image.
Setup on VirtualBox
We import the newly-downloaded image into VirtualBox.
Our general settings for this IOS-XRv look like below (your settings may be different depending on your hardware):
- Name: IOS-XRv-612
- Base Memory: 4096 MB
- Processors: 2
- Network Adapters: 4 (Enabled and Not attached)
Setup on GNS3
Next, we go to GNS3 to create a VirtualBox VM appliance with this IOS-XRv-612.
In General settings tab, we check ‘Start VM in headless mode’ and ‘Use as a linked base VM (experimental)’.
In Network tab, we choose four (4) Adapters, change ‘First port name’ to Management and ‘Name format’ to Gi0/0/0/{0} to match the order and name of interfaces in VirtualBox IOS-XRv image.
The IOS-XRv-612 appliance is now ready for us to use, connect and boot up.
At the end of booting process, hit ‘Enter’. The IOS-XRv will ask us to configure root-system username and secret. We choose ‘netlab’ as username.
To login, we can use our newly-configured account or cisco/cisco as indicated on the screen:
Basic configuration and testing
To continue, we basically configure IOS-XRv and R1 routers, and test whether they are working properly or not when connecting to each other like in the diagram.
In this scenario, we are going to test by pinging and detecting peers via CDP on both ends.
By default, CDP is disabled on IOS-XR device. We need to enable it globally and at interface level. Unlike IOS, we need to issue ‘commit’ command to confirm all changes on IOS-XR.
Configuring IOS-XRv and R1 routers:
Pinging peer routers:
Detecting peer routers via CDP:
Well, IOS-XRv router is working properly as we expect.
P.S: If you run a similar setup and cannot perform Ping test (timeout), please try to delete and reconnect the connection between IOS-XRv and R1 routers. I did the same J.
GNS3 is one of the renown and best network software simulator released in 2008. In GNS3 you can import Cisco IOS Router images and practice as much as you want.
We will explain you step by step process of How to add Cisco IOS (Dyanamips Images) to GNS3.

1. Download Cisco IOS (Dynamips images) GNS3
Gns3 Supported Cisco Ios Images
In order run Cisco IOS image in GNS3, first we need to download the images. We have provided two links – one from Cisco Website if you have the access and encase you do not have the access to Cisco Software you can use external link to download the images. Images provided below are strictly for education purpose and are not hosted on networkhunt.com server. We are just indexing the links find on internet for education purpose only.
You can download Cisco IOS (dynamips images) from below links.
1. Cisco Website (Cisco Access required to download images from cisco website.
2. Megahttps://mega.nz/#F!fpxnXIKB!twpa-jzH4ReWZFq5uZENZg
2. Add Cisco IOS (Dynamips images) to GNS3
Before Importing Cisco IOS images to GNS3, I am asumsing you have already installed GNS3 and if you have not installed GNS3 you can follow below link to install and configure GNS3 step by Step process.
How to install GNS3 step by step Process.
- Start GNS3 and Click Edit from top left bar and select Preferences.
- Now, we have to upload the Cisco IOS images to GNS3.
Once Preferences popup comes up, select IOS routers from Dyanamips tab.
Now click the IOS router option it will show you the option to add new IOS router image on right side.
- Select New Image option and click Browse button. Now select the downloaded IOS image file which you want to use for your lab.
- GNS3 supports both type of files compressed and decompressed and by default IOS files are compressed. If GNS3 asked to decompress the file, select no.
- Click next and continue the Wizard.
- If selected IOS belongs to an outdated device, wizard may display a warning message.In real life, using an outdated device is not recommended. Since GNS3 uses a real Cisco IOS, it also follows the same recommendation and warns us about the outdated IOS. If we are going to use this device only for CCNA exam preparation or to get some hands on experience on Cisco IOS, we can ignore this message.
- Now wizard extracts the hardware information (platform and chassis number) form selected IOS file and lists it in next screen along with an automatically populated device name.If extracted information does not match with device, select the correct platform and chassis number from drop down. If require, you may also adjust the device name.
Verify / adjust the information and Click Next button to continue
- Next screen allows us set the RAM size for this device. By default wizard automatically allocates the minimum recommended memory (RAM) for device. But if require, we can adjust it to match with our specific requirement.
- If selected IOS belongs to a modular device, next screen allows us to install the interfaces in available slots.
- Select appropriate interfaces and click Next button.
- Just like interfaces slots, if selected IOS belongs to a device which has WIC modules, next screen allows to install the WIC interface in WIC slots.
- Select the desire WIC interface and click Next button
- Next screen allows us to put a limit on CPU usage by this IOS. We should always specify this value. This value prevents a faulty or buggy IOS from consuming entire CPU cycles. Once this value is configured, GNS3 does not allow IOS from consuming CPU beyond this limit.
3. Calculating Idle-PC
Click Idle-PC finder button and use the suggested value in this field.
