Each chapter tackles a major subject area such as router configuration, routing protocols, bridging and switching, ISDN, access lists, IPX, and more. Each subject presents a mini-lab, walking you through the lab scenario and explaining in detail the commands used, why the authors chose the specific commands, and the resulting configurations. Comprehensive configuration and troubleshooting labs are added to the end of the book, allowing you to understand how routing technologies interact. This step-by-step lab scenario approach is designed to teach you how to apply the knowledge acquired in the process of becoming a CCNA.
