How to Configure Loopback Adapter in GNS3
To define Loopback interface in GNS3 program, firstly we need to add Microsoft Loopback Adapter in Windows operating system. You will then use it on GNS3. Once the IP address block is determined, it is recommended that you restart your computer against any flaws.
Loopback Adapter is a virtual network card, designed for use in test environments, as is well known. Test environments can be created and implemented with the Loopback Adapter.
In our previous tutorials, we discussed how to configure Cloud in GNS3 and how to integrate GNS3 with VMware Workstation. In this article, we will integrate with GNS3 program by adding Loopback Adapter on Windows 10 operating system.
How to Add Microsoft Loopback Adapter in GNS3?
We will add Microsoft Loopback Adapter on the Windows 10 operating system before proceeding with the steps to add Loopback Adapter in GNS3. Follow the steps below in order to integrate Loopback Adapter into GNS3.
Open the Run window on Windows 10 and type the command hdwwiz and click on the OK button. The Hdwwiz command is a short way to add the Loopback Adapter.
After the hardware addition wizard opens, click Next to continue.
Continue by selecting the Advanced option to manually add the Loopback Adapter.
In the Hardware types window, select the Network Adapters option and click Next.
Select Microsoft from the Manufacturer section and then continue by selecting the Microsoft KM-TEST Loopback Adapter in the right pane.
The following window provides a summary of the hardware to be installed. Click Next to continue.
The hardware addition process is complete and you can close the window by clicking the Finish button.
From the Network and Sharing Center, you can access the following window by clicking on Change adapter settings. We can see that our Loopback Adapter has successfully added. To avoid confusion with other network cards, you can change the name of the Loopback Adapter.
Double click on GNS3Loopback.
We need to set an IP address for the GNS3Loopback network card. You can change the IP address settings here. After configuring the GNS3 Loopback Adapter IP address settings, click the OK button to save the settings.
Click on the Details button to check the Loopback Adapter configuration.
Restart your computer before step 12!
After restarting your computer, run the GNS3 program and create a new project.
Drag and drop one Router and Cloud to the GNS3 workspace. To configure Cloud1, click the Right Button / Configure button.
In the Cloud1 configuration window, we need to select the Loopback Adapter we added in the Ethernet Interfaces section. Once you have selected the GNS3Loopback adapter, click on the Add button.
We have successfully completed the GNS3 Loopback Adapter configuration steps. Click the OK button to save the settings.
To wire the Cisco Router with Cloud1, click on the cabling option and then click on Cloud1. As you can see in the image below, the Loopback Adapter will become selectable.
Give the IP address to the Cisco Router FastEthernet 0/0 interface and turn the interface on. Then test the connection by pinging the Loopback Adapter IP address.
Cloud1 and Cisco Router can communicate with each other.
Likewise, let’s test the connection by pinging the Cisco Router FastEthernet 0/0 interface from our physical computer. The Ping connection test is successful as shown below!
