INITIALIZATION

• Reboot NUT (reboot.rmt)
• Enable HA function (mip6EnableHA.rmt)
• Configure routing table of NUT (route.rmt)

Check Link1 routing table

  NUT
(Link0)   MN1X
   |       |
   | <---- | Echo Request
   | ----> | Echo Reply
   |       |

1. MN1X sends Echo Request
2. MN1X receives Echo Reply

• Initialize IPsec configuration (ipsecEnable.rmt, ipsecClearAll.rmt)
• Set IPsec configuration (ipsecSetSAD.rmt, ipsecSetSPD.rmt)
  • ESP transport mode (BU/BA)

TEST PROCEDURE

Check home registration

  NUT
(Link0)   MN1X
   |       |
   | <---- | BU (A=0, lifetime=0x0010) (SPI=0x101)
   | ----> | BA (status=132) (SPI=0x102) (*1)
   |       |

1. MN1X sends BU
    packet format is:
        Binding_Update_message_format_from_MN_to_HA_ESP.gif
2. MN1X receives BA (*1)
    packet format is:
        Binding_Acknowledgement_message_format_from_HA_toMN_ESP.gif

Check BCE

  NUT
(Link0)   MN1X
   |       |
   | <---- | Echo Request w/ HaO
   | ----> | BE (status=1) (*2)
   |       |

1. MN1X sends Echo Request w/ HaO
2. MN1X receives BE (*2)
    packet format is:
        Binding_Error_message_from_HA_to_MN.gif

JUDGEMENT

(*1) PASS: MN1X receives BA
(*2) PASS: MN1X receives BE

REFERENCE

   To begin processing the Binding Update, the home agent MUST perform
   the following sequence of tests:

   o  If the node implements only correspondent node functionality, or
      has not been configured to act as a home agent, then the node MUST
      reject the Binding Update.  The node MUST then also return a
      Binding Acknowledgement to the mobile node, in which the Status
      field is set to 131 (home registration not supported).

   o  Else, if the home address for the binding (the Home Address field
      in the packet's Home Address option) is not an on-link IPv6
      address with respect to the home agent's current Prefix List, then
      the home agent MUST reject the Binding Update and SHOULD return a
      Binding Acknowledgement to the mobile node, in which the Status
      field is set to 132 (not home subnet).
