[DNA] Re: No FastRA unless Landmark? (draft-pentland-dna-protocol-00)

Sorry to reply to myself again.

Also, the subsequent paragraph has the same logic.

"If the source address of the RS is NOT the unspecified address,
  AND the RS message contains a Landmark option, the router consumes
  one unicast send token and then builds a Router Advertisement as
  follows:"


It would be good to know why Hash Based Fast RA (based on the
source address only) requires the Landmark Option.
