JUDGEMENT

 (*1) PASS: HA0 receives the Binding Acknowledgement packet by reverse tunneling.
            Then, check whether this packet fills all of the following.
             - The Source Address(outer) is set to primary care-of address.
             - The Destination Address(outer) is set to HA address.
             - The Destination Address(inner) is set to the Source Address(inner)
               of Binding Update[19]. 
             - The Source Address(inner) is set to home address.
             - The Home Address destination option is not included.
             - The status is set to 0.

6.1 Mobility Header
                    
   The Mobility Header is an extension header used by mobile nodes,
   correspondent nodes, and home agents in all messaging related to the
   creation and management of bindings.  The subsections within this
   section describe the message types that may be sent using the
   Mobility Header.
                    
   Mobility Header messages MUST NOT be sent with a type 2 routing
   header, except as described in Section 9.5.4 for Binding
   Acknowledgement.  Mobility Header messages also MUST NOT be used with
   a Home Address destination option, except as described in Section
   11.7.1 and Section 11.7.2 for Binding Update.  Binding Update List or
   Binding Cache information (when present) for the destination MUST NOT
   be used in sending Mobility Header messages.  That is, Mobility
   Header messages bypass both the Binding Cache check described in
   Section 9.3.2 and the Binding Update List check described in Section
   11.3.1 which are normally performed for all packets.  This applies
   even to messages sent to or from a correspondent node which is itself
   a mobile node.
