IP Routing Primer

Book Description

A thorough guide to understanding IP behavior in a router-based network

  • Learn IP behavior in a Cisco router-based network from an expert

  • Examine proven, effective troubleshooting techniques to eliminate the need for additional technical support

  • Master IP fundamentals that everyone supporting an IP network needs to know

  • Study visual explanations of complex real-world scenarios

  • IP Routing Primer focuses on how IP routing behaves in a Cisco router environment and also shows how you can use Cisco routers as a learning tool. In addition to teaching the core fundamentals, this book enhances your ability to troubleshoot IP routing problems yourself, often eliminating the need to call for additional technical support. In instances where additional support is required, this book will help you work more efficiently with customer support engineers by enhancing your ability to describe problems correctly.

    The information is presented in an approachable, workbook-type format with dozens of detailed illustrations and real life scenarios integrated throughout.
