Hi vijay,
First, thanks for your questions.
So far this version doesn't mention inter-as multi-access links, an
alternative method, as you said,
of describing this kind of links is to treat them as multiple P2P links. I
will supplement this description
in the future revised version.
Best regards,
Mach

The draft does not seem to address multi-access links between ASes.
Should the inter-AS link only be a point to point link or you are trying
to model multi-access links as multiple P2P links ( in which case B.W
calculations etc would not be straightforward)
Regards
Vijay

Hi,
We have just submitted the second revision of our
I-D,draft-chen-ccamp-
ospf-interas-te-extensions.
The problem we are trying to solve is how a PCE or entry-point ASBR
can
select the exit-point ASBR for a TE LSP when it knows (from the ERO)
the
downstream AS or the downstream ASBR. We believe that IGP needs to
flood
the inter-AS TE links together with additional information about the
neighboring AS and ASBR. The problem arises for both the pd-path and
brpc
computation methods.
We would welcome your input on our problem statement and our proposed
solution.
Best regards,
Mach & Renhai
