COMMENT:
----------------------------------------------------------------------

Thanks for addressing my prior discuss comments in the updated draft,
noting them here to check before approval.

This should be pretty easy to address.  In the security consideration
section, the following recommendation appears:

 o  SBFDReflector MUST NOT look at the crypto sequence number before
      accepting the packet.

Could you please add text to say what happens (what attacks are possible)
if this is looked at?  There is nothing to stop the crypt sequence number
from being looked at, right?  Is there a way to actually prevent that?
