Objectives
Part 1: Test and Restore IPv4 Connectivity
Part 2: Test and Restore IPv6 Connectivity
Scenario
There are connectivity issues in this activity. In addition to gathering and documenting information about the
network, you will locate the problems and implement acceptable solutions to restore connectivity.
Note: The user EXEC password is cisco. The privileged EXEC password is class.
####### 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.
####### Type your answers here.
####### 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.
####### Type your answers here.
####### d. Enter Ctrl+C to stop the trace.
Open configuration window
####### e. Click R1. Press ENTER and log in to the router.
####### f. Enter the show ip interface brief command to list the interfaces and their status. There are two IPv
####### addresses on the router. One should have been recorded in Step 2a.
Question:
What is the other?10.10.
####### Type your answers here.
####### g. 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?10.10.1/32, 10.10.1/
####### Type your answers here.
####### h. Repeat steps 2e through 2g with R3 and record your answers.
10.10.1, 10.10.1/30, 10.10.1/32Type your answers here.
####### i. Click R2. Press ENTER and log into the router.
####### j. Enter the show ip interface brief command and record your addresses.
####### 10.10.1, 10.10.1 your addresses here.
####### k. Run more tests if it helps visualize the problem. Simulation mode is available.
Close configuration window
####### Packet Tracer - Use Ping and Traceroute to Test Network Connectivity
####### e. Click R3. Press ENTER and log in to the router.
####### f. Enter the show ipv6 interface brief command to list the interfaces and their status. There are two IPv
####### addresses on the router. One should match the gateway address recorded in Step 1d.
Question:
Is there a discrepancy? Yes
####### Type your answers here.
####### g. Run more tests if it helps visualize the problem. Simulation mode is available.
Close a command prompt
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 is using the wrong default gateway configurationanswers here.
####### What solution would you propose to correct the problem?
Configure PC4 with the correct default gateway address: FE80::3 your answers here.
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? Yes
####### Type your answers here.
Step 6: Document the solution.
