Describe the limitations of PPP.
What will be an ideal response?
PPP does a great job of handling authentication for point-to-point connections, but it has some limitations. The biggest problem is that, in many cases, a network might have more than one point for an initiator to enter. PPP assumes that the authenticator at the endpoint has all the user name and password information, but that's not necessarily true. In traditional modem communication, for example, an ISP has a large bank of modems to support any number of users. When a user dials in, the modem bank provides the first available connection, but that means that any modem in the bank has to support any of the users. You cannot put the database containing all user names and passwords on every modem.
