  • 1.1 IOU Licensing Part 2

Downlaods

IOU Virtual Vmware Image ➡

Cisco L2 and L3 Images for IOU ➡

Import IOU in VirtualBox

The IOU Vmware zip file contains a full load of stuffs. You need only one.

VirtualBox IOU VM Host Settings

Castle defense upgrade hacked. After that open the vmdk file in VirtualBox and do some little changes in settings. Set the memory requirement as 256MB and it is enough to open the IOU VM.

Before you start the VM, do not forget to set the Virtual Network Adapter settings as Host Only.

Now time to fire up the VM and after successful booting the VirtualBox console will come up with a login prompt with a notification to browse the VM through browser to upload the L2 and L3 IOS file(here the IP address is set to 192.168.56.101 and the port is 8000 to access the http portal).

Username: root

Password: cisco

Uploading IOS to IOU VM

Now open the browser and upload the necessary files.

Url to open the VM http portal: http://192.168.56.101:8000/upload

Dont worry. These files are available on “L2 & L3 IOU IOS” zipFile.

IOU Licencing

Before starting the GNS3, need to license the VM. Go through the Video.

Upload Keygen to IOU VM

Either have to download the KeyGen.py or take it from the zip file itself and upload it to the VM.

Run the Keygen in IOU VM

Now write some simple command into the VM console.

Now you are half done to the licensing. I am taking the rest aside and will discuss after GNS3 setup.

Import the IOU VM Instances into GNS3

In GNS go to Preference>IOU Devices and then select a new . After the new IOU prompt come set the server type as remote(by default) .

Step 1 : Selecting Server Type

Step 2 : Mount the IOU image

Now mount the IOU image by simply copy and paste the path from the browser(it is a file located in 192.168.56.101:8000).

IOU Licensing Part 2

Now come to the rest of the licensing procedure.

IOURC Setup

Go to preferences> IOU on UNIX and you need to provide the absolute path of the iourc.txt file located in your local drive.

In the same way you can bring the L3 IOS also.

Launch the IOU Devices (L2 & L3) in GNS3

Now check how these IOU L2 and L3 devices being reflected in the GNS3 window.

You are ready to play with the Cisco switches. Here you can simulate almost all kind of toplogy, features, protocols & configurations.

Thank You —

Gns3 Supported Routers IOS Image list

In this article you will find the Cisco supported IOS list for the most famous network simulator/emulator that is Gns3. There are many different router IOS which are supported by the GNS3. Gns3 support different router images directly, some of them are need to be uncompressed before using it in gns3 while for some devices you are required the virtual machines of those images like IOU. You can also emulate the juniper router and IOU image using their VM images in gns3. Even you can run the Cisco XR images with gns3 that work with virtualBox, VMware and with KVM.

There are some Cisco 15.x IOS images which are support by gns3 as well. But currently 15.x images are only supported by the Cisco 7200 series in GNS3. List of compatible images from 7200 series is as under:

You can also use Qemu GNS3 emulates an IDS 4235/4215 Sensor. The software IPS is known to run with release 6.0.

Juniper routers on Gns3

There are some VM available through which you can use juniper router on GNS3.

Hosts or virtual PC on GNS3

You can use virtual host with other cisco devices in following ways:

• Qemu host
• VirtualBox VM
• Linux Tinycore
• you can connect your physical machine with gns3 using gns3 cloud
