PPP Overview

PPPprovides a method for transmitting protocol datagrams at the Data Link Layer over serial point-to-point links. PPP provides the following services:

vLink Control Protocol (LCP) to establish, con®gure, and test the link connection.

vEncapsulation protocol for encapsulating protocol datagrams over serial point-to-point links.

vAuthentication protocols (APs) to validate the identity of a peer (remote) unit, and to submit your own identity to the peer for validation.

vNetwork Control Protocols (NCPs) for establishing and con®guring different network layer protocols. PPP allows the use of multiple network layer protocols.

Figure 26 on page 450 shows some examples of point-to-point serial links.
