Configuring BGP on Cisco Routers (BGP)

Configuring BGP on Cisco Routers (BGP) v4.0 provides students with in-depth knowledge of Border Gateway Protocol (BGP), the routing protocol that is one of the foundations of the Internet and New World technologies such as Multiprotocol Label Switching (MPLS).

This curriculum covers the theory of BGP, configuration of BGP on Cisco IOS routers, detailed troubleshooting information, and hands-on exercises that provide learners with the skills that they need to configure and troubleshoot BGP networks in customer environments. Different service solutions in the curriculum cover BGP network design issues and usage rules for various BGP features, preparing learners to design and implement efficient, optimal, and trouble free BGP networks.

Target Audience
Primary target audience:

• This course is intended primarily for network administrators, network engineers, network managers and systems engineers who would like to implement BGP.

Secondary target audience:

• This course is intended for network designers and project managers. The course is also recommended to all individuals preparing for BGP exam.

Prerequisites
To fully benefit from this course, students should have the following prerequisite skills and knowledge:

• 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 v2.0, Part 1 (ICND1 v2.0) and Part 2 (ICND2 v2.0),     or
• Interconnecting Cisco Networking Devices: Accelerated Version 2.0 (CCNAX v2.0)
• Implementing Cisco IP Routing (ROUTE v2.0)
• Building Cisco Service Provider Next-Generation Networks Part 1 (SPNGN1) v1.2
• Building Cisco Service Provider Next-Generation Networks Part 2 (SPNGN2) v1.2 

Course Objectives
After completion of this course, students 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 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 protoco in a typical BGP network.
