A detailed examination of interior routing protocols
CCIE Professional Development: Routing TCP/IP, Volume I, takes readers from a basic understanding of routers and routing protocols through a detailed examination of each of the IP interior routing protocols: RIP, RIP2, IGRP, EIGRP, OSPF, and IS-IS. In addition to specific protocols, important general topics such as redistribution, default routes and on-demand routing, route filtering, and route maps are covered. The book emphasizes techniques for designing networks that efficiently utilize and integrate the IP routing protocols. You will gain a deep understanding of IP routing protocols and learn best-practice techniques for implementing these protocols using Cisco routers. As well, this book will help you master the skills necessary to become an effective CCIE.
Each protocol-specific chapter opens with thorough and lucid coverage of the protocol's capabilities and characteristics. Following sections contain configuration and troubleshooting case studies that cover Cisco specific configuration of the protocol and all commands available for it on the most recent Cisco IOS Software version. Finally, review questions and configuration and troubleshooting exercises on each protocol provide an opportunity to practice for the CCIE exam.
The Cisco effort to facilitate the creation of competent network operations center (NOC) and information systems (IS) staff is exemplified in its CCIE program. To support these efforts, Cisco Press is working closely with CCIE program management to create information products that help build the knowledge and expertise of NOC and IS professionals, as well as provide up-to-date, accurate information on technologies addressed in the CCIE program.
The CCIE Professional Development Series volumes are based on CCIE program guidelines from Cisco. This series is a set of technology-specific volumes designed to meet the needs of CCIE candidates.
This book is part of the Cisco CCIE Professional Development Series from Cisco Press, which offers expert-level instruction on network design, deployment, and support methodologies to help networking professionals manage complex networks and prepare for CCIE exams.
