How to configure PAP {Password Authentication Protocol} on cisco routers

This article is all about how to configure PAP on cisco routers. In the previous article, we learn about how to create VLANs on cisco switches. Now in this tutorial, we learn about routers and their protocols. PAP is an authentication method that can be used over Point to Point link. Here we read a word Authentication that means you can use authentication to verify a router’s identity when it is connecting into your router options for authentication including CHAP and PAP.

So let’s start here how to configure PAP on cisco routers.
