Most chapters focus on a setting up a separate class of devices that may be emulated by GNS3. The Book of GNS3 is about getting things working. The book also dedicates a large amount of coverage to topics related to running GNS3 on Linux.

Neumann described QEMU procedures that could also be applied to creating virtual machines for open-source routers using the QEMU hypervisor. As another example, when discussing Juniper Olive in Chapter 6, Mr. For example, four of the first five chapters of the book cover general GNS3 topics useful to all users including those emulating open-source routers. I found that there is some information that would be useful to people using GNS3 to emulate open-source routers.Įven though most of the book covers Cisco or Juniper topics, information useful to open-source networking researchers is spread throughout the book so it is worth reading the entire book. I have written several posts about using GNS3 to emulate open-source routers, and I wondered if The Book of GNS3 included similar information. While I read through this book, I looked for the parts that are relevant to my interests in open-source routing software, including software-defined networking, and open-source network simulators. How does this book help those who want to use open-source routers in GNS3? Read the rest of my review to find out.

Neumann spends most of the book discussing how to set up GNS3 to run commercial routers and, as much as is possible, switches. Most users of GNS3 use it to emulate networks of commercial routers from vendors such as Cisco and Juniper. However, I think the main beneficiaries will be new or inexperienced users of GNS3.

Experienced users will find some new information in this book, especially about the new features available in GNS3 1.x. It offers detailed installation and configuration information for GNS3 1.x in one easy-to-access volume. The Book of GNS3 effectively serves as a user manual for GNS3. This book covers the new version of GNS3, GNS3 1.x. No Starch Press recently sent me a preview copy of a new book about the GNS3 network simulator, titled The Book of GNS3 written by Jason Neumann.
