1. Introduction

   PPP has three main components:

      1. A method for encapsulating multi-protocol datagrams.

      2. A Link Control Protocol (LCP) for establishing, configuring,
         and testing the data-link connection.

      3. A family of Network Control Protocols for establishing and
         configuring different network-layer protocols.

   In order to establish communications over a point-to-point link, each
   end of the PPP link must first send LCP packets to configure and test
   the data link.  After the link has been established and optional
   facilities have been negotiated as needed by the LCP, PPP must send
   IPXCP packets to choose and configure the IPX network-layer protocol.
   Once IPXCP has reached the Opened state, IPX datagrams can be sent
   over the link.

   The link will remain configured for communications until explicit LCP
   or IPXCP packets close the link down, or until some external event
   occurs (an inactivity timer expires or network administrator
   intervention).
