Sometimes it is tough to configure our network topology using gns3 IOS images even if we are going to set virtual tunneling protocol ( VTP ) or Virtual Local Area Network (VLAN) Layer2 devices. Therefore We have an another option, Which is “GNS3 IOU images.”
Let’s Start;
GNS3 is getting a bit dated, due to its ability to only support really old Cisco IOS images. Check out Cisco's official tool, VIRL. I would put 12GB of RAM into your machine if you want to do any kind of serious simulation. #1 – Select IOS image. Select New Image and click Browse to find the Cisco IOS file you downloaded previously. In this example, we are installing a Cisco 1700 router. Once you selected the image, click Next. #2 – Name the router. After finishing the installation, the router will be on our list, ready to use.
- To able to run IOU images on GNS3 we should have to done with following steps.
Username is “root” password “cisco” all lower case.
2. Please make sure you network adapter on WM bridged ( Automatic ). You should configure it manually.

3. we have downloaded and to be able to run WM,
4. You will learn which network(subnet) you are on for figure out your IP address Type on shell prompt ”
&after
5. Type on shell prompt “ifconfig.” to get your iovm’s ip address.
6.After you have learned your IP address, you will need to Connect Gns3-iouv server
http://(IOU VMI address):8000/uploadhttp://192.168.1.16:8000/upload
ex.( http://192.168.1.16:8000/upload )
The user will find an IOU image using Google search, and it should match with your GNS3 version (1.4.6, 1.5.x, 1.5.x)
These images that I am currently using without any issue for ( VTP VLAN STP, 1q, BGP, OSPF, EIGRP … configurations)

7. You may need to change your GNS3 WM name, and please check out the picture.
8.After you have successfully uploaded your images on http://(yourgns3-iouv_ipaddress):8000/upload …
9.Open GNS3 Application go to edit-> preferences tab-> server->remoteuser.
10.You will need to add gns3-iouv VM’s(HOST) IP address. Username “root”, password “cisco” , add and apply.
11.When you have found the related images, the file comes with “iourc.txt” file which is your license. Go ahead and copy the file.

Moreover, finally you will need to add images IOU devices segment, you should be able to run WMS.
Thank you.
If you have any question, please do leave a comment.
