Hello,
We're currently discussing necessity of multi-level hierarchy
in OSPF on the WG mail list.
The idea is to implement SPF-based interarea routing
with more than two levels of topology abstraction and
route aggregation (we have two levels in OSPF at the
moment level1 being intra-area routing and level2 being
the inter-area one).
I have some thoughts on how this could be done,
but the main question is whether there is a demand
for it or not.
Everyone is really welcome to share opinions.
Thanks in advance,

Can anyone provide me with a comprehensive list of phone carriers
offering ISDN PRI Provisioning and Leased Lines (no Internet) from
T1 to OC3 within New York Area ?

If you would like to see what a contingency plan looks like, the
Securities Industry Association released its industry Y2K contingency
plan yesterday.
http://www.sia.com/year_2000/pdf/Y2KReport.pdf
The SIA tends to refer to the Internet as the "web." How many network
planning folks were aware one alternative for maintaining market operations
is using the web to post prices? I'm glad the financial industry has
such confidence in our ability to continue to deliver service even if
other communication systems fail.
Also after the NANOG meeting I received a few additional comments on my
presentation. I would like to clarify a few things.
1) I did not mean to imply that DRA has completed all of its Y2K
preparations. See Year 2000 Readiness Disclosure Statement.
2) The US Government is (at least one US Senator has strongly suggested
it, so it seems pretty likely it will be done) setting up a Y2K network
which is independent of the normal telephone network (satellite, HF radio,
and other government communication assets) including electric grid
controllers and 'major' telephone company management centers. However, at
the current time no ISP NOC has asked or been asked to participate. Even
at those companies which have both a voice NMCC and an ISP NOC, the ISP
part of the company has generally been left out. I covered some of
the reasons in my talk (although perhaps a bit obliquely).
3) I'm not recommending using the FCC 'emergency' rule to attempt ISP NOC
communication. I think even the hams would agree, without training and
experience such ad hoc radio networks tend to quickly become unusable.
And no, I don't think having a ham license is sufficient (or necessary)
experience. I'd rather teach 10 law firm receptionists how to use a
radio if I want to be sure the message will be delivered to the correct
person without being garbled, for many of the same reasons you don't
hire your typical telephone engineer as a telephone receptionist.

Shouldn't be reading press releases, but..
I'm having a hard time reconciling an ISP owned exchange
that claims to continue to be neutral. Interested in hearing
what imapct other operators see on this exchange.

PS. I'm a happy PAIX customer and a happy above.net peer.
No gripes.
Perhaps a bit off-topic and I apologize in advance. I am looking for a
colo system integrator in the Chicago area (preferrably a Cisco Gold
Partner). Please reply directly to me.
Thanks,
