Why spend a fortune on routers, when Linux systems can do the exact same job, for a tiny fraction of the cost? Linux routers are inexpensive, flexible, stable, adaptable, expandable, easy to administer, and based on proven technology. In this start-to-finish tutorial, you'll learn exactly how to implement Linux based routing -- hands-on. In Linux Routers, Tony Mancil covers many of the leading applications for routers, including Linux as an Ethernet router, a frame relay router, an Internet router, and even an extranet router. Mancil walks through deploying Linux routers; shows how the same Linux system can act as both a Web server and a router; and presents in-depth coverage of Linux router administration, including monitoring, high-availability strategies, and more. Mancil, who has run Linux routers in production environments for more than three years, offers unparalleled insight into avoiding and solving problems, and coping with the less-intuitive aspects of Linux router configuration.
