Category: GNS3

GNS3 is an open-source platform that we often prefer in network engineering. Here, I offer comprehensive guides for those who want to set up a virtual laboratory. Everything you need is available from installation steps to virtualization solutions. Beginners can also receive step-by-step support from the GNS3 Installation subcategory.

But if you need more flexible options with the GNS3 VM server, a section is available. If you’re interested in routing, look at our content on the Cisco Router page. Plus, I have detailed the Cisco Switch for switching operations. As a result, thanks to all this content, you can make a solid start to professional Cisco network design.

How to Fix uBridge Root Access Error in GNS3

Are you getting this error while using the GNS3 network simulator on Linux systems? The error message is: Root Access requires root access or the capability to interact with network adapters.

If so, you need to change the access permissions of the uBridge folder. By following the steps in this article, you will be able to run GNS3 without any problems!

Download vIOS-L2 Image for GNS3

When discussing network creation, GNS3 and vIOS-L2 are among the first things that come to mind. However, you can better understand these tools without the need for actual hardware.

To make GNS3 work well, you’ll need specific files, like the vIOS-L2 image. That’s because you’re not only using one switch in the emulator program. Additionally, you’ll use a router to help information move between networks.

How to Import an Appliance in GNS3

In this article, we’re going to explore importing an L2 appliance to GNS3. Cisco IOU (IOS on Unix) is like a pretend version of Cisco IOS that runs on Unix-type operating systems. It lets network engineers try out complex network setups and test different situations without having real hardware.

When you add an appliance to GNS3, you can make more realistic and advanced network simulations, including make-believe versions of Cisco switches and routers. We’ll guide you through each step, explaining how to download, install, and set up GNS3 to use the L2 appliance.

Cisco IOS Download for GNS3

GNS3 is a trendy tool for preparing for Cisco exams. To emulate the use of network devices like routers and switches on GNS3, you need to download Cisco IOS images.

So, these images are essential for making sure you can do the same things with Cisco devices in a virtual world.

How to Configure Loopback Adapter in GNS3

Using GNS3, you can add your PC to your network designs instead of virtual machines. You can select existing network adapters or add a Loopback network adapter. So, a GNS3 Loopback Adapter allows you to communicate with other PCs or virtual systems on the same network.

You can make more detailed network plans when you add a Loopback adapter to your GNS3 program. Also, combining your computer with virtual systems helps you create more advanced projects.

How to Add Layer 3 Switch in GNS3

The GNS3 software, which we use to enhance our knowledge of computer networks, also supports Layer 3 Switch devices. In the always-changing world of networks, we often use L3 switches to ensure data travels well between our devices. So, we provide efficient data transmission and communication among devices in our environment.

To prepare for tests from Cisco or other companies, we use advanced network tools using GNS3. Also, if we like networking, we try to improve. In this article, we’ll examine why we use GNS3 Layer 3 switches in the emulator program and how we set them up.

How to Add Layer 2 Switch in GNS3

Adding a Layer 2 Switch to GNS3 can significantly improve your practice sessions if you prepare for Cisco pass exams. Using a network device such as an L2 Switch involves creating a new project, selecting its type, and configuring its settings. Also, this device lets you connect your virtual computers or other network devices.

After setting up the switch, you can use various switching concepts such as VLAN, STP, and EtherChannel in your topology. In short, you can gain valuable experience and improve your skills before taking the genuine exam by simulating devices used in the real world.

How to Add Cisco IOS Router to GNS3 and GNS3 VM

If you know a lot about computer networks, you’ve probably heard of GNS3 and a Cisco IOS Router. GNS3 is a program that lets you make complicated network setups. It helps you use routers, switches, or firewalls without needing any physical equipment.

Cisco IOS is the active system that works on Cisco routers and switches. When you add these IOS images into graphical network software, you can practice on a computer. This way, you can prepare for Cisco’s really well-known network tests. In this article, we’ll show you how to add or import these IOS devices to the GNS3 emulator program.
