                  Binding Revocation for IPv6 Mobility

Abstract

   This document defines a binding revocation mechanism to terminate a
   mobile node's mobility session and the associated resources.  This
   mechanism can be used both with base Mobile IPv6 and its extensions,
   such as Proxy Mobile IPv6.  The mechanism allows the mobility entity
   which initiates the revocation procedure to request its peer to
   terminate either one, multiple or all specified Binding Cache
   entries.
