Configuring BGP on Cisco Routers

Configuring BGP on Cisco Routers provides students with an in-depth knowledge of Border Gateway Protocol (BGP), a routing protocol that is one of the foundations of the Internet and New World technologies such as Multiprotocol Label Switching (MPLS).

This course focuses on the theory of BGP, the configuration and troubleshooting of BGP on Cisco IOS routers. Extensive use of hands on labs has been incoporated into this curriculum to ensure learners have the skills required to configure and troublshoot BGP networks in customer environments.  

Each student will have their own virtual pod of equipment with access to the labs 24x7 for 90 days.

Target Audience

Service Provider and Enterprise network engineers that design,deploy and maintain core IP network infrastructures running BGP.

Learning Objectives

After you complete this course you will be able to:

  • 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 route selection process in a network scenario where 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 autonomous systems.
  • Enable route reflection and confederations as possible solutions to BGP scaling issues in a typical service provider network with multiple BGP connections to other autonomous systems.
  • Describe the available BGP tools and features to optimize the scalability of the BGP routing protocol in a typical BGP network.

Pre-Requisites

Attendees should meet the following prerequisites:

  • Intermediate to advanced Knowledge of Cisco IOS Software configuration - CCNA Routing and Switching or CCNA Service Provider recommended.
  • Prior attendance of the ROUTE course is strongly recommended.
