I'm not sure what are the IP-AS attack and the routing layer attack
and whether you are worrying about attacks today or year 3010.

So, before continuing discussion, I think you should write a draft
precisely defining problems including the attacks. The draft may
be more than 100 pages long.

It should be noted, however, that, it is likely that I point out the
attacks are identical, if I have enough time to read everal lines of
the draft.

The point of previous discussion was that RPKI is useless for such
prevention. Read the ML log.

With A+P, it will be reached in year 3010 or later.
