The Border Gateway Protocol (BGP) is central to communication among the routers that move data from domain to domain. Cisco BGP-4 Command and Configuration Handbook
explains how to use all Internetwork Operating System (IOS) commands having to do with BGP-4, documenting the purpose and syntax of each and presenting an example of appropriate use for most. This book is both a fantastic reference--it's easy to locate the entry that describes the command that interests you--and an excellent learning tool. You'll want to consult it each time you're presented with an inter-domain routing problem, either for the IOS commands you need to implement your ideas or for the author's thoughts about how to engineer your solution.
Coverage of each BGP-4 command goes beyond what's in the IOS documentation. Each entry begins with a syntax summary (in large type, bless the book's designers), a concise statement of what the command does and a note of the IOS version in which the command first appeared. After that, there's a configuration example consisting of input and output listings from the IOS command line and some suggestions (in the form of explicit IOS commands) on how to troubleshoot related problems. Sometimes there's a schematic "hockey puck" diagram to clarify configurations. This is a valuable reference and--for hardcore IOS fans and Cisco Certified Internetwork Expert (CCIE) candidates--an informative straight-through read. --David Wall

As the means by which Internet destinations are communicated between subscribers and service providers, BGP-4 provides a critical function for Internet operations. Whether associated with Internet service providers or enterprise networks that depend heavily on the Internet, a background in BGP-4 is essential. Moving beyond background information, BGP contains a great number of commands, and practical information on those commands is difficult to come by.
Cisco BGP-4 Command and Configuration Handbook is an exhaustive practical reference to the commands contained within BGP-4. For each command/subcommand, author Bill Parkhurst explains the intended use or function and how to properly configure it. Then he presents scenarios to demonstrate every facet of the command and its use, along with appropriate show and debug commands. Through the discussion of functionality and the scenario-based configuration examples, Cisco BGP-4 Command and Configuration Handbook will help you gain a thorough understanding of the practical side of BGP-4.
