Abstract

The Point-to-Point Protocol (PPP) provides a method for transmitting

datagrams over serial point-to-point links. PPP is composed of

1) a method for encapsulating datagrams over serial links,

2) an extensible Link Control Protocol (LCP), and

3) a family of Network Control Protocols (NCP) for establishing

and configuring different network-layer protocols.

The PPP encapsulating scheme, the basic LCP, and an NCP for

controlling and establishing the Internet Protocol (IP) (called the

IP Control Protocol, IPCP) are defined in The Point-to-Point Protocol

(PPP) [1].

This document defines the intial options used by the LCP and IPCP. It

also defines a method of Link Quality Monitoring and a simple

authentication scheme.
