OK, thanks.

OK.

I think it was meant that using PPK doesn't directly influence peer authentication 
in IKEv2, but I agree that the wording is not clear enough.
It's probably better to rephrase it:

    This document does not replace the
    authentication checks that the protocol does; instead, they are 
    strengthened by using an additional secret key.

Is it better?

OK.

THank you,
