P Packet T Tracer - Testing g Connec ctivity with w Trac ceroute T Topology O Objectives Part 1: Te est End-to-End Connectivity with the e tracert Com mmand Part 2: Co ompare to th he traceroute e Command on o a Router B Backgroun nd This activity is designe ed to help you troubleshoott network con nnectivity issues using com mmands to trace the m source to de estination. Yo ou are require ed to examine e the output off tracert (the Windows com mmand) route from and trace eroute (the IO OS command)) as packets traverse t the network n and determine d the cause of a network issue. Afte er the issue is s corrected, use u the tracerrt and tracero oute comman nds to verify the t completion. P Part 1: Test T End-to-End Connectiv C vity with the t tracerrt Comma and S Step 1: Send a ping frrom one end of the nettwork to the e other end. Click PC1 1 and open the Command Prompt. Ping PC3 at 10.1 1.0.2. What message m is displayed as a result of the ping? S Step 2: Tra ace the routte from PC1 1 to determine where in n the path connectivity c y fails. a. From the Comman nd Prompt off PC1, enter the t tracert 10 0.1.0.2 command. b. When n you receive the Requestt timed out message, m presss Ctrl+C. Wh hat was the first IP addresss listed in the tra acert output? ? © 2013 Cisco and d/or its affiliates. All rights reserve ed. This docume ent is Cisco Public. Page 1 of 3 Packet Tracer - Testing Connectivity with Traceroute c. Observe the results of the tracert command. What is the last address reached with the tracert command? Step 3: Correct the network problem. a. Compare the last address reached with the tracert command with the network addresses listed on the topology. The furthest device from the host 10.0.0.2 with an address in the network range found is the point of failure. What devices have addresses configured for the network where the failure occurred? b. Click RouterC and then the CLI tab. c. What is the status of the interfaces? d. Compare the IP addresses on the interfaces with the network addresses on the topology. Does there appear to be anything extraordinary? e. Make the necessary changes to restore connectivity; however, do not change the subnets. What is solution? Step 4: Verify that end-to-end connectivity is established. a. From the PC1 Command Prompt, enter the tracert 10.1.0.2 command. b. Observe the output from the tracert command. Was the command successful? Part 2: Compare to the traceroute Command on a Router a. Click RouterA and then the CLI tab. b. Enter the traceroute 10.1.0.2 command. Did the command complete successfully? c. Compare the output from the router traceroute command with the PC tracert command. What is noticeably different about the list of addresses returned? © 2013 Cisco and/or its affiliates. All rights reserved. This document is Cisco Public.
