Configuring BGP on Cisco Routers V4.0 (BGP)


Configuring BGP on Cisco Routers V4.0 (BGP)

What you’ll learn in this course

The Configuring BGP on Cisco Routers V4.0 (BGP) course teaches the underlying foundations of the Internet and new-world technologies such as Multiprotocol Label Switching (MPLS). It prepares students to design and implement efficient, optimal, and trouble-free BGP networks covering:

The theory of BGP and configuration of BGP on Cisco IOS routers

Detailed troubleshooting information and hands-on exercises that provide students with the skills needed to configure and troubleshoot BGP networks in customer environments

BGP network design issues and usage rules for various BGP features

Who should enroll

The main audience for this course is the following: People with positions such as

· Network administrators

· Network engineers

· Network managers

· Systems engineers (who would like to implement BGP)

Course Prerequisites

The knowledge and skills that a learner must have before attending this course are as follows:

· Intermediate to advanced knowledge of Cisco IOS Software configuration

· Configuring and troubleshooting RIP, EIGRP, OSPF and IS-IS

· Skills and knowledge equivalent to those learned in:

· Interconnecting Cisco Networking Devices Part 1 (ICND1) and Part 2 (ICND2), or

· Interconnecting Cisco Networking Devices: Accelerated Version (CCNAX)

· Implementing Cisco IP Routing (ROUTE)

· Building Cisco Service Provider Next-Generation Networks Part 1 (SPNGN1)

· Building Cisco Service Provider Next-Generation Networks Part 2 (SPNGN2)

Course Objectives

After taking this course, you should 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 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 autonomous systems.

· Enable route reflection as possible solution 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
