GNS3 is open source software that emulates Cisco router and switch hardware to simulate complex networks. You can use GNS3 on any computer to experiment with various router configurations, study for that next big Cisco certification, or build the ubernetwork of your wildest dreams—all without plugging in a single physical network cable.Networks are everywhere. They connect all kinds of businesses, from local bookshops to huge corporations to universities, across multiple cities and continents. Networks are conceptually simple to understand, yet they are becoming more and more complex, with innovation in areas such as Software Defined Networks (SDN), the Internet of Things (IoT), and other technologies just around the corner.
To understand, design, and manage today’s complex networks, network professionals must not only master the theory but also practice and validate concepts in these ever-changing environments. This is where GNS3 comes in: it gives users immense flexibility to build their own networking labs, allowing them to experiment with new network features, capture packets to dissect protocols, and verify configurations for later deployment on real devices. All of this is done without the need to invest in expensive hardware. GNS3 is a powerful and adaptable tool, evolving to now integrate multiple vendors and iterating to meet the growing needs of network professionals. But how do you master GNS3 itself and where do you start?
In The Book of GNS3, Jason covers everything that network engineers, administrators, and people studying for certifications need to get started, from walking you through installing and configuring GNS3 to creating and managing your projects. Jason digs deep while showcasing the true breadth of the software, covering topics like how to capture network packets, how to connect to real networks and live switches, and how to include advanced systems such as Juniper’s vSRX Firefly and Cisco’s IOS-XRv in your labs. He spends significant time explaining concepts and giving tips that will make you an expert user in no time.
