The International Travel Agency wants to run EIGRP on its core, branch, and regional routers. You are asked to configure EIGRP and test its ability to install alternate routes in the event of link failure. | Configuring EIGRP Fault Tolerance _ I__ Fa0 0 24 S0 0 30 S0 1 30 EIGRP AS 100 S0 0 30 S0 0 30 Fa0 0 24 SanJose Fa0 0 24 SanJose Objective In this lab you configure EIGRP over a full-mesh topology so that you can test and observe DUAL replace a successor with a feasible successor after a link failure. Scenario The International Travel Agency wants to run EIGRP on its core branch and regional routers. You are asked to configure EIGRP and test its ability to install alternate routes in the event of link failure. Step 1 Build and configure the network according to the diagram configuring EIGRP as indicated for AS 100. Check each serial interface s bandwidth and change to 1544 if necessary. Use the show interface command to verify the configuration. Use ping and show ip route to verify your work and test connectivity between all routers. Step 2 Verify that EIGRP maintains all routes to destination networks in its topology table. 1 - 3 Semester 5 Advanced Routing - Lab Copyright 2001 Cisco Systems Inc.
