             Host Mobility with the Host Identity Protocol
                     draft-ietf-hip-rfc5206-bis-05

Abstract

   This document defines mobility extensions to the Host Identity
   Protocol (HIP).  Specifically, this document defines a general
   "LOCATOR_SET" parameter for HIP messages that allows for a HIP host
   to notify peers about alternate addresses at which it may be reached.
   This document also defines elements of procedure for mobility of a
   HIP host -- the process by which a host dynamically changes the
   primary locator that it uses to receive packets.  While the same
   LOCATOR_SET parameter can also be used to support end-host
   multihoming, detailed procedures are out of scope for this document.
   This document obsoletes RFC 5206.
