9.5.1 Receiving Binding Updates
When the Home Registration (H) bit is not set, the following are also required:
o A Nonce Indices mobility option MUST be present, and the Home and
Care-of Nonce Index values in this option MUST be recent enough to
be recognized by the correspondent node. (Care-of Nonce Index
values are not inspected for requests to delete a binding.)
(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.
