> | Lab 13.1.6 Troubleshooting 5-router network - Overview Estimated time: 30 min. Objectives: Troubleshoot problems in the 5-router lab network Document the problems found and corrective action taken Prepare for Part B of the Final Exam (Router Lab Troubleshooting) Background: For this lab, your instructor has created/introduced multiple problems in the network. You have a limited amount of time in which to find and solve the problems so that you can get the entire network up and running. The tools that you may use for the hardware are in your tool kit. The tools that you may use for the software (IOS) include ping, trace ip route, telnet, and show arp. You may use your Engineering Journal and any Web-based resources (including the curriculum) that are available. As you discover the problems you will document them along with what you did to correct them. Tools / Preparation: Prior to starting this lab you should have the equipment for the standard 5-router lab available. All routers and workstations should be properly configured. You will be asked to leave the room and your instructor or lab assistant will introduce 3 to 5 problems into the lab setup. Step 1 - Review the physical connections on the standard lab setup. Review the standard semester 2 lab diagram in the overview section of this lab and check all physical devices, cables and connections. Step 2 - Troubleshooting induced network problems. Basic Problem descriptions: a) We cannot ping a host on LAB-E's network from a host on LAB-A's network. b) We cannot telnet from one router to another router's host name The instructor will induce multiple problems (3 to 5) into the network (see answers section) that can cause these high level symptoms. Your team will have a fixed time period (20 to 30 minutes) to correct the problems. You may use your journals and toolkits to troubleshoot the problems. Step 3 - Document the problems discovered. Write down the problems as you encounter them and then indicate what you did to correct them. When you are able to ping from a Lab-A workstation to a Lab-E workstation and telnet from one router to another router's host name, have the instructor verify that you have corrected all problems.
