=head1 REFERENCE

=begin html
<PRE>
&lt;draft-ietf-mobileip-ipv6-15.txt&gt;
</PRE>
<PRE>
8.5. Sending Binding Acknowledgements
</PRE>
<PRE>
   <B>When any node receives a packet containing a Binding Update option</B>
   <B>in which the Acknowledge (A) bit is set, it <FONT COLOR="#FF0000">MUST</FONT> return a Binding</B>
   <B>Acknowledgement option acknowledging receipt of the Binding Update.</B>
   If the node accepts the Binding Update and creates or updates
   an entry in its Binding Cache for this binding, and the `A' bit
   was set in the Binding Update, the Status field in the Binding
   Acknowledgement MUST be set to a value less than 128; if, on the
   other hand the Binding Update is accepted and the `A' bit is not set,
   the node SHOULD NOT send a Binding Acknowledgement.  If the node
   rejects the Binding Update and does not create or update an entry for
   this binding, a Binding Acknowledgement MUST be sent even if the `A'
   bit was not sent, and the Status field in the Binding Acknowledgement
   MUST be set to a value greater than or equal to 128.  Specific values
   for the Status field are described in Section 5.2 and in the most
   recent "Assigned Numbers" [26].
