2. Real World Application
In this lab you will learn how to configure a GNS3 Ethernet NIO (Network Input/Output) Cloud used in labs
found in the Free CCNA Workbook.
If you are using GNS3 then throughout the Free CCNA Workbook you will be required to connect to the router
using your host machine. The workbook was created so GNS3 can be used while running on a Windows XP
Professional PC. While running GNS3 on other operating systems such as Windows Vista or Windows 7 is
possible but due to the compatibility of GNS3, it is currently recommended that you run GNS3 on a Windows
XP machine.
This lab will show you how to configure a Microsoft Loopback interface used for local host IP connectivity to
an Ethernet interface of a Cisco device within GNS3. This simulates physical connectivity to the emulated Cisco
platform.
You can choose to bind the GNS3 Cloud to your physical adapter rather then the Microsoft Loopback Adapter;
when using the physical adapter this gives you the option to connect to the GNS3 Cisco devices from another
device within your LAN, however connecting to the GNS3 Cisco device via local host will have a high
probability of crashing the Dynamips Engine.
Please note that you may have compatibility issues with Windows 7 and Windows Vista 64bit loopback
interfaces, a 32bit operating system is recommended.
Lab Prerequisites
Load the Free CCNA Workbook GNS3 topology and establish a console session to SW1
Lab Objectives
Install a MS Loopback interface on Windows XP
Configure an IP address on the newly created MS Loopback adapter.
Create a Cloud interface in GNS3 and bind it to the newly created MS Loopback Adapter.
Verify your connectivity by assigning an IP address to SW1 in the same subnet that you assigned to the
MS Loopback adapter. For lab demonstration purposes, Free CCNA Workbook devices will use
192.168.255.1-8/24 and the host machine is 192.168.255.10/24
Lab Instruction
Step 1. – Navigate to the Control Panel by clicking Start > Control Panel or by loading My Computer and
clicking Control Panel down the left side bar within “Other Places”
Once in control panel double click the “Add Hardware” icon and the Add Hardware Wizard will pop up as

3. shown below;
After clicking next the Wizard will automatically search for new hardware; this may take a few minutes;
Once the Wizard has finished searching for new hardware and none is found you will be asked rather or not the
new hardware is already connected, bullet the Yes, I have connected the hardware and click next

4. Slide the scroll bar on the right side of the list down to the bottom and highlight Add new hardware device as
shown below and click next;
You will now be prompted rather or not you want the Add New Hardware wizard to automatically search for the
new hardware. Click the bottom bullet that says Install the hardware that I manually select from a list
(Advanced) as shown below and click next;

5. You’re now given a list of different types of hardware you can choose to install. Scroll down the list and select
Network Adapters as shown below and click next;
The next window will display a Manufacture list on the left hand side and devices available to install by that
manufacture on the right. Some computers may have multiple manufacture options to choose from, if so then
select the Microsoft manufacture in the list on the left hand side then select the Microsoft Loopback Adapter in
the list on the right hand side as shown below and click next;

6. You are now shown the hardware device you are attempting to install prior to installing it as shown below, just
click next and Windows will install the device. A window with a progress bar may pop up showing the progress
of the device driver installation;
Once the Microsoft Loopback Adapter is installed click finish as shown below and restart your computer;

7. Step 2. – Configure an IP address on the newly created MS Loopback adapter.
The Microsoft Loopback Adapter will appear as a physical NIC when you load Network Connections found in
Control Panel. You can configure an IP address on this MS Loopback Adapter just as you would a physical NIC.
Use an IP address range that does not conflict with any networks that you’re connected to. A Great example
would be 192.168.255.10/24
Step 3. – Create a Cloud interface in GNS3 and bind it to the newly created MS Loopback Adapter.
Load up the Free CCNA Workbook GNS3 topology and in the Node Type list on the left side of the GNS3
window you will see a node called Cloud. Left click that node and hold down the mouse button and drag that
node onto the topology pane as shown below;

8. Once the Cloud is in the topology pane, double click the cloud and you will see the Cloud tree and the list of
Clouds available for configuration. Click Cloud 1 named CL1 as shown below;
Once in the Cloud configuration you will notice 2 text boxes under Generic Ethernet NIO (require
Administrator access). If you have multiple network adapters you will see them all listed when clicking on the
first textbox. Find the Adapter that has the name Network Adapter: ‘MS LoopBack’ and add that adapter by
clicking the ADD. Once completely you will see the Ethernet uid in the large textbox as shown below;

9. After Binding the MS Loopback network adapter to Cloud 1 (CL1) its time to logically connect Cloud 1 to SW1
in the Free CCNA Workbook GNS3 topology. This is done by clicking on the RJ-45 Ethernet plug as shown in
the picture below and selecting FastEthernet;
When logically connecting devices in GNS3, you can only connect the medium that the interfaces on the virtual
devices are rated at. e.g; you cannot connect GigaEthernet to a FastEthernet interface on SW1.
After selecting the FastEthernet medium from the “Add a Link” button shown in the previous picture click on

10. the cloud as shown below and you will be given the NIO UID that is associated with that cloud, highlight and
click the NIO UID;
Now drag the link sourced from Cloud 1 (CL1) over to SW1 in the topology and click SW1. This will
automatically terminate the link to the FastEthernet1/0 interface as its the only available interface to terminate
the link to.
Step 4. – Verify your connectivity by assigning an IP address to SW1 in the same subnet that you assigned to the
MS Loopback adapter. For lab demonstration purposes, Free CCNA Workbook devices will use
192.168.255.1-8/24 and the host machine is 192.168.255.10/24.
Now its time to test connectivity so assign an IP address to SW1′s FastEthernet1/0 interface and ping the local
host from SW1′s command line as shown below;
Router con0 is now available
