Now you have GNS3 ready to rock, but you need to configure it. Continue hitting Next until the end, leaving all the default options. So, without wasting time, we can simply download it from their website, or click the link below.īe sure to select all components (unless you already have NPCAP as we do). Many people don’t believe that in the first place, but the truth is that GNS3 is open-source. It allows you to save a lot of money because you don’t need to purchase hardware. We will only focus get you going with this awesome software so that you can try your own labs. We won’t explain networking commands, or how to configure the devices. This GNS3 Tutorial will explain to you how to install and use GNS3. After this GNS3 Tutorial, you will be able to do the same. Instead, GNS3 runs real Cisco IOS: it is like having a real router on your lap! You can see where this is going: with GNS3, you are going to have many more features.īecause of that, people use GNS3 to prepare for complex stuff like CCNP and CCIE labs.
In other words, Packet Tracer is software that reproduces the behavior of a router: if you type this command, you get that output and so on. While Packet Tracer emulates network devices, GNS3 simulates them. So, why is GNS3 better than Packet Tracer? The reason for that lays in the core difference between the two.
You can drag routers in a central window, connect them with cables and configure them. You can think of it as the big brother of the Cisco Packet Tracer. GNS3 stands for Graphical Network Simulator 3, and it is exactly what the name says: a software to simulate networks. Introducing GNS3īefore we start the GNS3 Tutorial, we should explain what is GNS3. Again, If you want to test a scenario before implementing it at work, GNS3 is the product for you. If you want to study CCNP without buying expensive hardware, you are in the right place. So, if you can’t stand the “Command not implemented in this version of Packet Tracer” message, you are in the right place. We will give you the tools to train for CCNP and CCIE! With this GNS3 Tutorial, we will teach you how to create a virtual data center on your laptop. Today, we take practice to the next level. If you have followed the Free CCNA course, you know that you can start practicing with Packet Tracer. Practice with you the confidence you need to avoid that. In your career, you will face many moments when things aren’t working the way they should.
Learning the concepts of networking is crucial, but still worthless with no practice. From the Network tab, you can add interfaces to the Switch.ĭouble-click on the switch to open the CLI command prompt, and use the show vlan brief command to check if the device is working.If you are a network engineer (or starting to be one), you know the importance of practice.
