![]() Want to study for your CCNA or CCNP or even CCIE exams? Just build a topology with Cisco devices and go for it.ĭocker support became available in version 2.0. Want to try network penetration testing? Just add a Kali Linux appliance to your topologies. Want a AAA TACAS or RADIUS server? Just add it to GNS3 by leveraging the prebuilt appliances in the GNS3 marketplace. GNS3 also allows you to add virtual machines of almost any description to your GNS3 topologies. Today, you can practice labs of many types and GNS3 supports many networking vendors: Cisco, Juniper, Arista, Aruba, Cumulus, and others. You can even contribute to the development of GNS3. Because GNS3 is an open source software, you can check all the source code on GitHub. This is unlike other tools on the market today that are either vendor proprietary or paid for software. You do not have to pay to use GNS3 in either a personal or commercial environment. Because he had benefited so much from open source software at university, he decided make GNS3 open source and free to use. Jeremy, however, took things even further. What are the benefits of GNS3? Open Source It is used by most companies in the Fortune 500 and by millions of users around the world. Since Jeremy’s trip in 2006, GNS3 has grown exponentially and has been downloaded over 17 million times. Since then, practicing for certifications like the Cisco Certified Network Associate Routing & Switching (CCNA), Cisco Certified Network Professional (CCNP), and even Cisco Certified Internetwork Expert (CCIE) exams and labs have never been the same. You can still access the alpha code on SourceForge here. Thankfully, Jeremy wrote and released his creation-GNS3-to the world in June 2007. But, in those days, this was an amazing breakthrough for engineers around the world. What with all the talk about Network Function Virtualization (NFV) and Software Defined Networks (SDN) and other buzzwords used by the networking industry today. Why not run Cisco networking equipment virtually on your laptop so you can practice anywhere? And why not make it easy to create networks by simply dragging devices into a network topology and linking them with various types of interfaces? While on a boat at sea, Jeremy Grossmann (the creator of GNS3), came up with an amazing idea. He also needed a cool project for his university degree. How would he practice on Cisco labs without physical Cisco equipment? He wanted to practice Cisco Certified Network Professional (CCNP) labs from home, but wasn’t able to. He was facing the same issue all of us faced in those days. ![]() Have you got that kind of money just for labs? A Frenchman and a vacationįortunately, in 2006, a Frenchman Jeremy Grossman was taking a trip to Mayotte island near Madagascar and Southern Africa. Other network engineers have even spent the equivalent of $1 million building huge labs in their basements for practice and testing. Who needed heating? Just get a bunch of Cisco routers and switches to heat the house! Fortunately, I passed my CCIE exam, so it was worth it.īut, what a nightmare it was trying to get hold of equipment to practice for exams in those days. I remember having equipment at my house making lots of noise and generating lots of heat. In those days, you had to spend lots of money either buying or renting equipment to practice. GNS3 was the 4th hottest skill trending in 2018 on Udemy, the global online learning marketplace with 80,000 online courses, 24+ million learners, and thousands of businesses.īack in the day, when I was studying for my Cisco Certified Internetwork Expert (CCIE certification) lab exam, the only way to practice and complete labs was by using physical equipment. All kinds of routers, depending on the ISO used.Īdditionally, the users will have the possibility to configure all the parameters of each of these elements, in such a way that they will know with total certainty which response they will have, once they start working.ĭownload GNS3 for free to now beforehand how a network will work thanks to simulation.The development of GNS3 virtual network simulator in 2007 was a game changer for network engineers from all corners of the world. ![]() With GNS3 ( Graphic Network Simulation) the user will have the possibility to be able to choose each of the elements which will form part of a computer network.īy means of the different objects which GNS3 offers, the user will be able to select the different variants of node which will interconnect the network, with possibility to add: Have access to the information graphically To be able to simulate the interaction between the different elements which will finally form part of the networks you can use GNS3. When it comes to designing any computer network is essential to know beforehand how it is going to work, because they usually have a high cost. ![]()
