REFERENCE

   The lifetime of the Binding Cache entry depends on a number of
   factors:

   o  The lifetime for the Binding Cache entry MUST NOT be greater than
      the Lifetime value specified in the Binding Update.

   o  The lifetime for the Binding Cache entry MUST NOT be greater than
      the remaining valid lifetime for the subnet prefix in the mobile
      node's home address specified with the Binding Update.  The
      remaining valid lifetime for this prefix is determined by the home
      agent based on its own Prefix List entry for this prefix [12].

      The remaining preferred lifetime SHOULD NOT have any impact on the
      lifetime for the binding cache entry.

      The home agent MUST remove a binding when the valid lifetime of
      the prefix associated with it expires.

   o  The home agent MAY further decrease the specified lifetime for the
      binding, for example based on a local policy.  The resulting
      lifetime is stored by the home agent in the Binding Cache entry,
      and this Binding Cache entry MUST be deleted by the home agent
      after the expiration of this lifetime.
