Lab Objective:
The objective of this lab exercise is to configure two routers sharing a back-to-back Serial link encapsulated by PPP to authenticate each other using Password Authentication Protocol (PAP). By default, PPP connections are not authenticated or secured.
Lab Purpose:
PPP PAP authentication configuration is a fundamental skill. One of the main reasons that PPP is so popular is because it has the capability to be secured and devices communicating using PPP can be authenticated. PAP authentication is the least preferred method to secure PPP as it sends usernames and passwords in clear text. However, as a Cisco engineer, as well as in the Cisco CCNA exam, you will be expected to know how to configure PPP PAP authentication.
