Abstract

   Mobile IP [RFC 2002] defines media-independent procedures by which a
   Mobile Node can maintain existing transport and application-layer
   connections despite changing its point-of-attachment to the Internet
   and without changing its IP address.  PPP [RFC 1661] provides a
   standard method for transporting multi-protocol packets over point-
   to-point links.  As currently specified, Mobile IP Foreign Agents
   which support Mobile Node connections via PPP can do so only by first
   assigning unique addresses to those Mobile Nodes, defeating one of
   the primary advantages of Foreign Agents.  This documents corrects
   this problem by defining the Mobile-IPv4 Configuration Option to the
   Internet Protocol Control Protocol (IPCP) [RFC 1332].  Using this
   option, two peers can communicate their support for Mobile IP during
   the IPCP phase of PPP.  Familiarity with Mobile IP [RFC 2002], IPCP
   [RFC 1332], and PPP [RFC 1661] is assumed.
