# REFERENCE

    <draft-ietf-mobileip-ipv6-19.txt>
    9.3.1. Receiving Packets with Home Address Destination Option
    ----------------------------------------------------------------
       Packets containing a Home Address option MUST also be dropped if
       there is no corresponding Binding Cache entry for the given home
       address.  A corresponding Binding Cache entry MUST have the currently
       registered care-of address equal to the source address of the packet.
       These tests MUST NOT be done for packets that contain a Binding
       Update and a Home Address option.
       If the packet is dropped due the above tests, the correspondent node
       SHOULD send the Binding Error message as described in Section 9.3.3.
       The Status field in this message should be set to 1 (unknown binding
       for Home Address destination option).
