9.5.1 Receiving Binding Updates

   Before accepting a Binding Update, the receiving node MUST validate
   the Binding Update according to the following tests:

      (snip)

   o  The Sequence Number field in the Binding Update is greater than
      the Sequence Number received in the previous valid Binding Update
      for this home address, if any.

6.1.8 Binding Acknowledgement Message

   Sequence #

      The Sequence Number in the Binding Acknowledgement is copied from
      the Sequence Number field in the Binding Update.  It is used by
      the mobile node in matching this Binding Acknowledgement with an
      outstanding Binding Update.
