REFERENCE

<draft-ietf-mobileip-ipv6-19.txt>
9.5.1. Receiving Binding Updates
----------------------------------------------------------------
    -  If the Lifetime specified in the Binding Update is zero or the
       specified care-of address matches the home address for the
       binding, then this is a request to delete the mobile node's
       cached binding.  The update MUST include a valid home nonce index
       (the care-of nonce index MUST be ignored by the correspondent
       node).  In this case, generation of the binding management key
       depends exclusively on the home keygen token (Section 5.2.5).  If
       the Home Registration (H) bit is set in the Binding Update, the
       Binding Update is processed according to the procedure specified
       in Section 10.3.2; otherwise, it is processed according to the
       procedure specified in Section 9.5.3.

<draft-ietf-mobileip-ipv6-19.txt>
9.5.4. Sending Binding Acknowledgements
----------------------------------------------------------------
   If the Source Address is the home address of the mobile node, i.e.,
   the Binding Update did not contain a Home Address destination option,
   then the Binding Acknowledgement MUST be sent to that address,
   and the routing header MUST NOT be used.  Otherwise, the Binding
   Acknowledgement MUST be sent using a type 2 routing header which
   contains the mobile node's home address.
