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.

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 was the successful IPv4 address.
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? It
reached 10.10.1.17 for the IPv4 address.
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 IPv4 addresses on the router. One should have been recorded in Step 2a.
Question:
What is the other?
The other one I saw was 10.10.1.6
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?
10.10.1.6 and 10.10.1.4
h. Repeat steps 2e through 2g with R3 and record your answers.
10.10.1.10, 10.1.1.8, and 10.10.1.10 were the addresses that came up.
i. Click R2. Press ENTER and log into the router.
j. Enter the show ip interface brief command and record your addresses.
10.10.1.2 and 10.10.1.4

k. Run more tests if it helps visualize the problem. Simulation mode is available. Close
configuration window
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?
The R2 router’s Serial 0/0/0 interface has been configured with the wrong IP
address.
What solution would you propose to correct the problem?
When I input the correct IP address on the R2 router’s Serial 0/0/0 interface, the
issue should be resolved.
Step 4: Implement the plan.
Implement the solution you proposed in Step 3b.
Step 5: Verify that connectivity is restored. a. From
PC1 test connectivity to PC3.
b. From PC3 test connectivity to PC1. Question:
Is the problem resolved?
Yes the problem is resolved.
Step 6: Document the solution.
I corrected the faulty Serial IP address by identifying the connectivity failure, reviewing the IP
routing information, and collecting diagnostic data. The fix was applied by updating the
Serial0/0/0 interface from 10.10.1.2 to 10.10.1.5.
Part 2: Test and Restore IPv6 Connectivity
Step 1: Use ipv6config and ping to verify connectivity. a. Click
PC2 and open the Command Prompt.
b. Enter the ipv6config /all command to collect the IPv6 information. Complete the
Addressing Table with the IPv6 address, subnet prefix, and default gateway.
c. Click PC4 and open the Command Prompt.
d. Enter the ipv6config /all command to collect the IPv6 information. Complete the
Addressing Table with the IPv6 address, subnet prefix, and default gateway.
e. Test connectivity between PC2 and PC4. The ping should fail.
Step 2: Locate the source of connectivity failure.
a. From PC2, enter the necessary command to trace the route to PC4. Question:
What is the last successful IPv6 address that was reached?

b. The trace will eventually end after 30 attempts. Enter Ctrl+C to stop the trace before 30
attempts.
c. From PC4, enter the necessary command to trace the route to PC2. Question:
What is the last successful IPv6 address that was reached? No, the
IPv6 address was reached when checked.
d. Enter Ctrl+C to stop the trace.
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 IPv6 addresses on the router. One should match the gateway address
recorded in Step 1d. Question:
Is there a discrepancy?
Type your answers here.
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 is configured with the wrong default gateway address, so I need to correct it,
which I did.
What solution would you propose to correct the problem? Reconfigure PC4
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
Step 6: Document the solution. End of
