PPP Validation (Instructor Version)

Instructor Note: Red font color or Gray highlights indicate text that appears in the instructor copy only.

Objective

Use show and debug commands to troubleshoot PPP.

Instructor Note: This activity should be completed by groups of three students, but it can be completed by all

individuals in a class at one time.

Scenario

Three friends who are enrolled in the Cisco Networking Academy want to check their knowledge of PPP network

configuration.

They set up a contest where each person will be tested on configuring PPP with defined PPP scenario

requirements and varying options. Each person devises a different configuration scenario.

The next day they get together and test each other’s configuration using their PPP scenario requirements.

Resources

 Packet Tracer software

 Stopwatch or timer

Step 1: Open Packet Tracer.

a. Create a two-router topology with a serial connection.

b. Include one PC and switch attached to each router.

Step 2: Complete the scenarios.

a. Start the Scenario 1 configuration.

b. The instructor calls the time when the scenario is completed; all students and groups must stop their

configuration work at that time.

c. The instructor checks the validity of the completed scenario configuration.

1) The devices must be able to successfully ping from one end of the topology to the other.

2) All scenario options requested must be present in the final topology.

3) The instructor may ask you to prove your work by choosing different show and debug commands to

display the configuration output.

The student, or group, completing the scenario correctly is declared the winner.

d. Begin the same process as Scenario 2.

1) Delete Scenario 1 configurations, but you can re-use the same.

2) Complete Steps 1 and 2 again using the next scenario’s requirements.

Suggested Scenarios include:

Scenario 1

 Address the topology using IPv4.

 Configure PPP encapsulation with CHAP.
