The Point-to-Point Protocol (PPP) [1] provides a standard method for
transporting multi-protocol datagrams over point-to-point links.  PPP
defines an extensible Link Control Protocol (LCP) for establishing,
configuring, and testing the data-link connection; and a family of
Network Control Protocols (NCPs) for establishing and configuring
different network-layer protocols. This document defines a general
mechanism for proprietary vendor extensions. This document is a
product of the Point-to-Point Extensions Working Group of the IETF.
