Configuring BGP on Cisco Routers v4.0 (BGP)

The Configuring BGP on Cisco Routers (BGP) v4.0 introduces the learners to the in-depth knowledge of Border Gateway Protocol (BGP), the routing protocol that is one of the foundations of the Internet and New World technologies such as Multiprotocol Label Switching (MPLS). This course covers the theory of BGP, configuration of BGP on Cisco IOS routers, detailed troubleshooting information, and hands-on exercises that provide learners with the skills that they need to configure and troubleshoot BGP networks in customer environments. Different service solutions in the course cover BGP network design issues and usage rules for various BGP features, preparing learners to design and implement efficient, optimal, and trouble-free BGP networks.
The goal of the course is to provide learners with in-depth knowledge of BGP. Upon completing this course, the learner will be able to meet these overall objectives:

  • Describe how to configure, monitor, and troubleshoot basic BGP to enable interdomain routing in a network scenario with multiple domains
  • Describe how to use BGP policy controls to influence the BGP route selection process in a network scenario in which you must support connections to multiple ISPs
  • Describe how to use BGP attributes to influence the route selection process in a network scenario where you must support multiple connections
  • Describe how to successfully connect the customer network to the Internet in a network scenario in which multiple connections must be implemented
  • Describe how to configure the service provider network to behave as a transit AS in a typical implementation with multiple BGP connections to other ASs
  • Enable route reflection as possible solution to BGP scaling issues in a typical service provider network with multiple BGP connections to other ASs
  • Describe the available BGP tools and features to optimize the scalability of the BGP routing protocol in a typical BGP network
