INITIALIZATION

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

Check Link0 routing table

JUDGEMENT

PASS: MN0X receives MPA

REFERENCE

   The home agent uses the following algorithm to determine when to send
   prefix information to the mobile node.

   o  If a mobile node sends a solicitation, answer right away.

   o  If no Mobile Prefix Advertisement has been sent to the mobile node
      in the last MaxMobPfxAdvInterval (see Section 13) seconds, then
      ensure that a transmission is scheduled.  The actual transmission
      time is randomized as described below.

   o  If a prefix matching the mobile node's home registration is added
      on the home subnet interface, or if its information changes in any
      way that does not deprecate the mobile node's address, ensure that
      a transmission is scheduled.  The actual transmission time is
      randomized as described below.

   o  If a home registration expires, cancel any scheduled
      advertisements to the mobile node.

   When sending a Mobile Prefix Advertisement to the mobile node, the
   home agent MUST construct the packet as follows:

   o  The Source Address in the packet's IPv6 header MUST be set to the
      home agent's IP address to which the mobile node addressed its
      current home registration, or its default global home agent
      address if no binding exists.

   o  If the advertisement was solicited, it MUST be destined to the
      source address of the solicitation.  If it was triggered by prefix
      changes or renumbering, the advertisement's destination will be
      the mobile node's home address in the binding which triggered the
      rule.

   o  A type 2 routing header MUST be included with the mobile node's
      home address.

   o  IPsec headers MUST be supported and SHOULD be used.

   o  The home agent MUST send the packet as it would any other unicast
      IPv6 packet that it originates.

   o  Set the Managed Address Configuration (M) flag if the
      corresponding flag has been set in any of the Router
      Advertisements from which the prefix information has been learned
      (including the ones sent by this home agent).

   o  Set the Other Stateful Configuration (O) flag if the corresponding
      flag has been set in any of the Router Advertisements from which
      the prefix information has been learned (including the ones sent
      by this home agent).
