Lab: Configuring PPP Encapsulation
Lab Objective:
The objective of this lab exercise is to enable PPP encapsulation on Cisco router Serial interfaces and verify the state of the PPP-encapsulated interfaces. This lab also covers debugging PPP links to see the different states of PPP negotiation
Lab Purpose:
PPP configuration and verification is a fundamental skill. PPP is one of the most popular Layer 2 protocols used on WANs. As a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure and verify PPP encapsulation.
Certification Level:
This lab is suitable for both CCENT and CCNA certification exam preparation
Lab Difficulty:
This lab has a difficulty rating of 4/10
Readiness Assessment:
When you are ready for your certification exam, you should complete this lab in no more than 10 minutes
Lab Topology:
Please use the following topology to complete this lab exercise:
Task 1:
Configure the hostnames on routers R1 and R2 as illustrated in the topology.
Task 2:
Enable the Serial interfaces on R1 and R2. The Serial0/0 interface on R2 is identified as the DCE in the topology. Use the appropriate show command to verify that this interface is indeed the DCE. Configure the DCE interface on R2 to providing clocking to R1. The clock speed should be 512Kbps. Verify that R1 receives clocking information from R2.
Task 3:
Enable PPP encapsulation on router R1 and R2 Seriaol0/0 interfaces. Configure IP addressing on R1 and R2 Serial0/0 interfaces as illustrated in the topology. Verify your interface encapsulation, which should now be PPP. Test connectivity between R1 and R2 by pinging between the routers over the PPP link.
Task 4:
Enable PPP link negotiation debugging on router R1. Next, issue the shutdown followed by the no shutdown command on Serial0/0. As the interface goes down and comes back up, you should observe the different phases of PPP link negotiation. Disable debugging when you are done.
