Overview/Description
The largest and most sophisticated network in the world today is none other than the Internet. Border Gateway Protocol makes this critical network possible. As if this fact is not enough, BGP is also one of the underlying foundations of new-world technologies such as Multi-protocol Label Switching (MPLS). This course covers the theory of BGP and the configuration of BGP on Cisco IOS routers. This course also provides detailed troubleshooting information and hands-on exercises that provide students with the skills needed 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 students to design and implement efficient, optimal, and trouble-free BGP networks.

Target Audience
This course is recommended for any student interested in mastering advanced Internet and related Cisco technologies. It is also perfect for students interested in pursuing Cisco’s Certified Internetwork Professional certification or the Cisco Certified Internetwork Expert.

Lesson Objectives

Configuring BGP on Cisco Routers (BGP) 3.2 Expert Encore

Given a network scenario with multiple domains - configure, monitor and troubleshoot basic BGP to enable inter-domain routing

Given a network scenario where connections to multiple ISPs must be supported, use BGP policy controls to influence the route selection process with minimal impact on BGP route processing

Given a network scenario where multiple connections must be supported, use BGP attributes to influence the route selection process

Given customer connectivity requirements, implement the correct BGP configuration to successfully connect the customer's network to the Internet

Given a typical service provider network with multiple BGP connections to other autonomous systems, enable the provider network to behave as a transit autonomous system

Given a typical service provider network, identify common BGP scaling issues and enable route reflection and confederation as possible solutions to these issues

Given a typical BGP network, use available BGP tools and features to optimize the scalability of the BGP routing protocol
