 A Revised Internet-Draft is available from the on-line Internet-Drafts 
 directories. This draft is a work item of the Point-to-Point Protocol 
 Extensions Working Group of the IETF.                                     


       Title     : Mobile IPv4 Configuration Option for PPP IPCP

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.

Send a message to:  mailserv@ds.internic.net. In the body type: 
     "FILE /internet-drafts/draft-ietf-pppext-ipcp-mip-01.txt".
							
NOTE: The mail server at ds.internic.net can return the document in
      MIME-encoded form by using the "mpack" utility.  To use this
      feature, insert the command "ENCODING mime" before the "FILE"
      command.  To decode the response(s), you will need "munpack" or
      a MIME-compliant mail reader.  Different MIME-compliant mail readers
      exhibit different behavior, especially when dealing with
      "multipart" MIME messages (i.e., documents which have been split
      up into multiple messages), so check your local documentation on
      how to manipulate these messages.
							
							

Below is the data which will enable a MIME compliant mail reader 
implementation to automatically retrieve the ASCII version
of the Internet-Draft.
