Cisco TSHOOT 2.0: Troubleshooting EIGRP and BGP

Professionals who work in complex network environments desiring the skills they need to maintain their networks and to diagnose and resolve network problems quickly and effectively. The TSHOOT learning path will provide information about troubleshooting and maintaining particular technologies, as well as procedural and organizational aspects of the troubleshooting and maintenance process. A large part of the training will consist of practicing these skills and reinforcing the concepts by putting them to use in a controlled environment. At the end of the learning path, you should have increased your skill level and developed a set of best practices that are based on your own experience that you can take back to your organization.

Enhanced Interior Gateway Routing Protocol (EIGRP) is a routing protocol commonly used in large enterprise networks. Troubleshooting problems related to the exchange of routing information is an essential skill for any network engineer that is involved in the implementation and maintenance of large routed enterprise networks that use EIGRP as the IGP. Enterprise networks may make use of the Border Gateway Protocol (BGP) to exchange routing information in a controlled fashion with external parties such as Internet service providers or other providers of IP-based services. The exterior gateway protocol BGP is often used in combination with an interior gateway protocol such as Enhanced Interior Gateway Routing Protocol (EIGRP) routing protocol. And performance problems on network devices can cause degraded application performance and connectivity issues resulting in problems at the business level. Understanding the mechanics of BGP and its interaction with interior gateways, and diagnosing and resolving BGP performance problems are important skills for any network support engineer. This course reviews EIGRP and BGP operations and details the use of Cisco IOS commands to gather information about EIGRP and BGP data structures and routing processes. The course also explains EIGRP and BGP neighborship and routing issues as well as the typical solutions.
