As one of the most predominantly deployed Interior Gateway Protocols, Open Shortest Path First (OSPF) demands a wealth of knowledge on the part of internetworking professionals working with it on a daily basis. Unfortunately, publicly available documentation on the OSPF command set varies from being too thin on coverage to being too demanding on the required equipment needed to test what the documentation covers. Cisco OSPF Command and Configuration Handbook is a clear, concise, and complete source of documentation for all Cisco IOS(r) Software OSPF commands. The way you use this book will depend on your objectives. If you are preparing for the CCIE written and lab exams, then this book can be used as a laboratory guide to learn the purpose and proper use of every OSPF command. If you are a network designer, then this book can be used as a ready reference for any OSPF command.Cisco OSPF Command and Configuration Handbook provides example scenarios that demonstrate the proper use of every OSPF command that can be implemented on a minimum number of routers. This will enable you to learn each command without requiring an extensive and expensive lab configuration. The scenarios clearly present the purpose and use of each command. Some of the examples lead you into common non-working situations in order to reinforce the understanding of the operation of the particular OSPF command. This book is part of the Cisco CCIE Professional Development Series, which offers expert-level instruction on network design, deployment, and support methodologies to help networking professionals manage complex networks and prepare for CCIE exams.
