Exactly. The ability to send host-initiated RSs through is mainly for
supporting SEND pass through, as this capability was deemed very
important by the WG.
Then I guess the obvious next question is how this interacts with SEND if
the original 3 RS messages are lost.
The AN-initiated RSs in this case will not be SEND protected RSs (since
we do not have the host's private key), but the edge router is still
free to send SEND protected RAs back to the host in response to this RS.
Then the host and the edge router can use SEND for protecting any
further ND messages.
Thanks
Suresh
