9.5.1 Receiving Binding Updates

   o  If the Lifetime specified in the Binding Update is nonzero and the
      specified care-of address is not equal to the home address for the
      binding, then this is a request to cache a binding for the home
      address.  If the Home Registration (H) bit is set in the Binding
      Update, the Binding Update is processed according to the procedure
      specified in Section 10.3.1; otherwise, it is processed according
      to the procedure specified in Section 9.5.2.

10.3.1 Primary Care-of Address Registration

   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).
