eap Mailing List: RE: Re: Issue 348: Definition of Lower Layer

[Narayanan, Vidya (vidyan]

So, by this definition, RADIUS or IKEv2, for e.g., would not be
classified as a lower layer? I see that the pass through mode figure in
RFC3748 alludes to this, but I thought for having the "lower layer" vs.
the "AAA" text in the stack was because AAA is more or less standard on
that link, while the "lower layer" between the peer and authenticator
could differ. 

Section 3.1 of RFC3748 applies to all layers that carry EAP, not just
between the peer and authenticator - isn't that right?
