Configuring BGP on Cisco Routers v4.0

The Configuring BGP on Cisco Routers (BGP) version 4.0 Cisco® Training course provides you with in-depth knowledge of Border Gateway Protocol (BGP), the routing protocol that is one of the underlying foundations of the Internet, and newer technologies such as Multiprotocol Label Switching (MPLS). This course prepares you to design and implement efficient, optimal, and trouble-free BGP networks. In addition, you learn the theory of BGP and how to configure BGP on Cisco IOS® routers. You learn detailed troubleshooting information and the skills necessary for configuring and troubleshooting BGP networks in customer environments. Finally, you learn about BGP network design issues and usage rules for various features.

Duration

The BGP course is a 5-day instructor-led training.

Target Audience

This course is designed for network engineers and technicians, support engineers, systems engineers, network analysts, and senior network administrators.

Objective

After completing this course, you should be able to:

• Configure, monitor, and troubleshoot basic BGP to enable interdomain 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 Internet service providers
• Use BGP attributes to influence the route selection process in a network scenario where you must support multiple connections
• Implement the correct BGP configuration to successfully connect the customer network to the Internet in a network scenario where you must support multiple connections
• Enable the provider network to behave as a transit autonomous system (AS) in a typical service provider network with multiple BGP connections to other autonomous systems
• Identify common BGP scaling issues and enable route reflection and confederations as possible solutions to these issues in a typical service provider network with multiple BGP connections to other autonomous systems

Prerequisites

The knowledge and skills necessary before attending this course are:

• Completion of Interconnecting Cisco Networking Devices (ICND1) or the Cisco CCNA® certification
• Completion of Building Scalable Cisco Internetworks (BSCI) or equivalent
