Packet Tracer - Use Ping and Traceroute to Test Network Connectivity Instructions Part 1: Test and Restore IPv4 Connectivity Step 1: Use ipconfig and ping to verify connectivity. a. Click PC1 and open the Command Prompt . b. Enter the ipconfig /all command to collect the IPv4 information. Complete the Addressing Table with the IPv4 address, subnet mask, and default gateway. c. Click PC3 and open the Command Prompt . d. Enter the ipconfig /all command to collect the IPv4 information. Complete the Addressing Table with the IPv4 address, subnet mask, and default gateway. e. Use the ping command to test connectivity between PC1 and PC3 . The ping should fail. Step 2: Locate the source of connectivity failure. a. From PC1 , enter the necessary command to trace the route to PC3 . Question: What is the last successful IPv4 address that was reached? 10.10.1.97 b. The trace will eventually end after 30 attempts. Enter Ctrl + C to stop the trace before 30 attempts. c. From PC3 , enter the necessary command to trace the route to PC1 . Question: What is the last successful IPv4 address that was reached? 10.10.1.17 Enter Ctrl + C to stop the trace. Open configuration window d. Click R1 . Press ENTER and log in to the router. e. Enter the show ip interface brief command to list the interfaces and their status. There are two IPv4 addresses on the router. One should have been recorded in Step 2a. Question: What is the other? 10.10.1.6 f. Enter the show ip route command to list the networks to which the router is connected. Note that there are two networks connected to the Serial0/0/1 interface. Question: What are they? 10.10.1.4/30 and 10.10.1.6/32 g. Repeat steps 2e through 2g with R3 and record your answers. 10.10.1.10 10.10.1.8/30 and 10.10.1.10/32 h. Click R2 . Press ENTER and log into the router. i. Enter the show ip interface brief command and record your addresses. 10.10.1.2 and 10.10.1.9 j. Run more tests if it helps visualize the problem. Simulation mode is available.

Packet Tracer - Use Ping and Traceroute to Test Network Connectivity f. Enter the show ipv6 interface brief command to list the interfaces and their status. There are two IPv6 addresses on the router. One should match the gateway address recorded in Step 1d. Question: Is there a discrepancy? No g. Run more tests if it helps visualize the problem. Simulation mode is available. Step 3: Propose a solution to solve the problem. Compare your answers in Step 2 to the documentation you have available for the network. Question: What is the error? PC4 Default Gateway is FE80::2 but should be FE80::3 What solution would you propose to correct the problem? Change the Default Gateway for PC4 to FE80::3 Step 4: Implement the plan. Implement the solution you proposed in Step 3b. Step 5: Verify that connectivity is restored. a. From PC2 test connectivity to PC4 . b. From PC4 test connectivity to PC2 . Question: Is the problem resolved? Type Yes Step 6: Document the solution. End of document © 2013 - 2019 Cisco and/or its affiliates. All rights reserved. Cisco Public Page 4 of 5 www.netacad.com
