The comprehensive, hands-on guide to all Cisco IOS(r) Software BGP-4 commands

  • The complete BGP-4 command reference
  • invaluable for network designers, engineers, and architects
  • Provides configuration, troubleshooting, and verification scenarios for every possible BGP-4 command supported by Cisco IOS Software that can be implemented on a minimum number of routers
  • Groups BGP-4 commands by area of implementation route aggregation, auto-summary, route filtering, and route advertisement, just to name a few
  • Provides clear and concise commentary on the initial release, purpose, syntax, and usage of each BGP-4 command
  • Offers excellent CCIE certification preparation from one of the CCIE Program Managers
  • Includes supplementary information on regular expressions, route map logic, and RFC 1771, A Border Gateway Protocol 4 (BGP-4)

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.
