Troubleshooting routing protocols

This chapter discusses common EIGRP configuration tasks. The emphasis is on ways in which EIGRP establishes relationships with adjacent routers, calculates primary and backup routes, and responds to failures in known routes to a particular destination. A network is made up of many devices, protocols, and media that allow data communication to occur. When a network component does not work correctly, it can affect the entire network. In any case, network engineers must quickly identify and troubleshoot problems when they arise. Learn about the features of balanced hybrid routing and EIGRP – the Cisco-proprietary routing protocol based on IGRP. Discover how to configure EIGRP and verify configuration. You'll also explore the process for troubleshooting routing protocols and be introduced to debugging commands.
