GNS3 offers multiple ways to emulate IOS. For older images, we use and maintain Dynamips; an emulator dedicated to emulate some Cisco hardware. Dynamips can run unmodified IOS images. In the new GNS3 1.4, there is a way to run a second category of switches and routers. These are classified as Routing and Switching virtual machines (or R+Svms) for short.

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;
- 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)
GNS3 IOU images

i86bi-linux-l2-adventerprisek9-15.1a
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.
*** Note: Please make sure your WMs are all in the same subnet!
