Updated: Draft liaison #6 - ASON OSPF Loop-detection

["Adrian Farrel" <adrian@olddog.co.uk>]

Hi,

I got a couple of comments that lead to some minor wording changes

There is no definition of any new
mechanism or LSA in this Internet-Draft: the use of a new
LSA or changes to the processing rules for existing LSAs
would inhibit the integration of ASON routing developments
within the IETF routing family and, while this may not be
an objective of the ASON architecture, it is an objective
of the IETF.

You suggest that the use of Area ID in the LSAs will
inhibit re-configuration of AREA IDs. We do not believe
that this is the case, and we will add text to the draft to
describe the necessary processing for this important, but
uncommon case.

Please note that the scope of this work (including the
loop-prevention mechanisms) is limited by the requirements
expressed in RFC 4258. A separate liaison to you has
requested a further review of RFC 4258. In the event that
substantive modifications to the requirements are made as a
result of your review, it will be necessary to consider
updating the solutions work. Such a process of publication
and revision is similar to the procedure applied within the
ITU.

Note also that the scope of this work (that is, of this
current Internet-Draft) is extensions to the OSPFv2 
protocol. The CCAMP working group would welcome 
contributions in the form of Internet-Drafts from anyone
who is interested in addressing the same problem space
through the IS-IS protocol.

Thank you for your continued support of this work.
