Linux Routing explains and demonstrates routing solutions for common network types, namely LANs, WANs, and VPNs, using various types of hardware, and then explores the inner workings of the daemons and commands used for routing in Linux.
The second half of the book revolves around specialized issues. These include building micro-kernels that provide additional routing speed and security; how routing is handled in a list of popular Linux distributions; security issues; traffic monitoring and control; and finally a variety of hardware and software packages available to those running or wanting to run Linux routers.
Whether you need routing for a small, subnetted network or a larger scale project, Linux Routing will help you to understand the complexities that come with setting up dynamic routing for complex network configurations on a Linux box. Along the way you'll learn about some of the more popular protocols available and when they are best used, how to configure key routing daemons and what else is available, and how to set up routing and related services in a wide variety of situations.
