Objectives<br />

Background<br />

• Load the trouble ticket device configuration files for each trouble ticket.<br />

• Diagnose and resolve problems related to network layer connectivity.<br />

• Diagnose and resolve problems related to EIGRP.<br />

• Document troubleshooting progress, configuration changes, and problem resolution.<br />

Because of the complexity of modern networks, Layer 3 routing issues are quite common and can also be<br />

difficult to troubleshoot. One of the most widely used enterprise routing protocols is Enhanced Interior<br />

Gateway Routing Protocol (EIGRP). It is a <strong>Cisco</strong> proprietary distance vector, classless routing protocol that<br />

was released in 1992 with <strong>Cisco</strong> IOS Release 9.21. EIGRP has features that are not commonly found in other<br />

distance vector routing protocols, such as the following:<br />

• Reliable Transport Protocol (RTP)<br />

• Bounded updates<br />

• Diffusing Update Algorithm (DUAL)<br />
