TheConfiguring BGP on Cisco Routers version 4.1 training teaches the underlying foundations of the Internet and new-world technologies such as Multiprotocol Label Switching (MPLS). It prepares students to design and implement efficient, optimal, and trouble-free BGP networks covering:

  • The theory of BGP and configuration of BGP on Cisco IOS routers
  • Detailed troubleshooting information and hands-on exercises that provide students with the skills needed to configure and troubleshoot BGP networks in customer environments
  • BGP network design issues and usage rules for various BGP features.

Skills Gained

Upon completing this course, the learner will be able to meet these overall objectives:

  • Implement the correct BGP configuration to allow your network to act as an ISP
  • Configure BGP with multiple BGP connections to other autonomous systems
  • Configure a provider network to behave as a transit autonomous system (AS)
  • Configure, monitor, and troubleshoot basic BGP to enable inter-domain routing in a network scenario with multiple domains
  • Use BGP policy controls to influence the route selection process with minimal impact on BGP route processing in a network scenario where you must support connections to multiple ISPs
  • Configure BGP to connect the customer network to the Internet when multiple connections must be implemented
  • Enable route reflection and confederations as possible solutions to BGP scaling issues
  • Optimize the scalability of the BGP routing protocol in a typical network

Who Can Benefit

The primary audience for this course is as follows:

  • Internet service providers
  • Networking professionals who need to connect to ISPs
  • CCIP and CCIE certification candidates
  • Individuals who need to understand how to configure Cisco routers for the BGP protocol
