Configuring BGP on Cisco Routers v3.2 (BGP)

Learn to optimally deploy BGP in your network. - 5-day instructor led course

Course Description

In this comprehensive 5-day Authorized Cisco course, you will gain an in-depth knowledge of BGP, the routing protocol that is one of the underlying foundations of the Internet. Explore the theory of BGP, advanced configuration of BGP on Cisco IOS routers, and detailed troubleshooting information. Our enhanced hands-on labs provide you with the skills needed to configure and troubleshoot BGP networks in both enterprise and service provider environments. Learn BGP network design issues and usage rules for various BGP features, and learn to design and implement efficient, optimal, and trouble-free BGP networks. This course is part of the recommended training for the CCIPT certification.

Course Objectives

• Use BGP policy controls
• Use BGP attributes to influence the route selection process
• 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

Intended Audience

Internet Service Providers, networking professionals who need to connect to ISPs, CCIP and CCIE certification candidates, and other individuals who need to understand how to configure Cisco routers for the BGP protocol.
