REFERENCE

(draft-ietf-mobileip-ipv6-24.txt)

9.5.1 Receiving Binding Updates

   If the Home Registration (H) bit is set, the Nonce Indices mobility
   option MUST NOT be present.

      (snip)

   For packets carrying Binding Updates that fail to satisfy all of
   these tests for any reason other than insufficiency of the Sequence
   Number, registration type change, or expired nonce index values, they
   MUST be silently discarded.
