Dear colleagues,
while the minutes of our RIPE44 session of the Routing WG have long been
prepared by Arife (thanks a lot for that), I would want to apologize my
neglect in not sending them out in a timely manner. This has slipped, and I
take this as a personal action to improve significantly for this meeting.
Please find the minutes below.
-----
RIPE 44, Amsterdam
Routing Working Group Session
28-January-2002 Minutes
Chair: Joachim Schmitz - JS395-RIPE
Co-chair: Joao Damas - joao(a)psg.com
Scribe: Arife Vural - AC10172-RIPE -- thank you!!
Participants: 99
A. Preliminaries
Joachim Schmitz welcomed us all to the meeting and declared it open. The
Participant's list was then handed out by the chair and Arife Vural from
RIPE-NCC volunteered to take the minutes.
Joachim Schmitz mentioned the overlap between Routing and DNS and IPv6. He
will try to avoid overlaps but it may not be ruled out entirely. During the
second slot of Routing WG there will be some issues discussed of IPv6
routing.
The minutes of the previous meeting at RIPE43 were approved.
There is no change to the agenda which was published before RIPE44.
B. Previous meetings actions
40.R1 Creating multi-homing doc is in progress Philip Smith and Joachim
Schmitz
had been discussing this offline. Joachim Schmitz suggested to drop this
item
until they may come up with something. Philip Smith thinks everything is
ready about the doc but he could not find the time to write them down.
41.R1 Work on RPSLng, M.Blanchet, D.Kessens, F.Parent, J.Schmitz, RIPE NCC.
41.R2 Work on RRCC, RIPE NCC
42.R1 Implement objects in database for unallocated IP address space, RIPE
NCC
42.R2 Arrange with other registries coverage of complete unallocated IP
address
space, RIPE NCC.
42.R3 Identify unallocated IP address space in RIS, RIS team.
C. Co-chair of Routing-WG
Joachim Schmitz said that Joao had already acted as an interim chairman when
Joachim could not attend the meeting and he had done a good job. Also, he has
been instrumental in several projects in the past related to the work of the
Routing WG as the RRCC project. So, Joachim proposed Joao be co-chair of
Routing-WG. Joao was accepted. After this assignment, Joachim is looking
for another co-chair in case of absence of Joao and Joachim. If anyone has a
candidate, let Joachim or Joao know.
D. Allocated Space, Status and Next Steps, Shane Kerr.
Slides are accessible from
http://www.ripe.net/ripe/meetings/archive/ripe-44/presentations/ripe44-rout…
-allocated/
Shane explained what their motivation is to publish allocated address space
in
the RIPE region. He said that he would like to help people to update their
filters by using this data. As a first step, obviously the internal and whois
DB must be made consistent.
Joachim Schmitz suggested to go and verify the unallocated address space and
then have seen how much of the unallocated space is announced.
Results get from
ftp://ftp.ripe.net/ripe/stats/issued/
Beyond Allocated Space, Shane gave a quick overview about the RRCC project
which
provides user to find out the inconsistencies between whois DB and routing
tables. Now, user can get an e-mail report in case of inconsistencies. Source
code of the tool is open to everyone and can be downloaded from
ftp://ftp.ripe.net/ripe/dbase/software/RRCC-0.2.tar.gz
E. Randy was not in Amsterdam and his presentation was cancelled.
F. Internet Routing Table Analysis Update, Philip Smith.
http://www.ripe.net/ripe/meetings/archive/ripe-44/presentations/ripe44-rout…
-bgptable.pdf
Philip Smith presented the latest changes and his observation of the Weekly
Routing Table Report. He added LACNIC into the report. He pointed out the
very
high number of prefixes /24:65807
CIDR Report (second part of Philip Smiths' presentation)
During the last couple of months, the increase in the number of aggregates
continues and growing of the BGP Routing Table is slow. 2002 looks better in
aggregation and growing is slow but it looks as if the trend in 2003 develops
more towards earlier steep increases seen. The reasons behind that are still
unknown, but the purpose of the CIDR report is diagnosis rather than
analysis.
Christian Panigl: When you look through PS reports, RIPE region is doing a
good aggregation.
G. Routing Information Services, Status and Plans, Matthew Williams.
Slides at
http://www.ripe.net/ripe/meetings/archive/ripe-44/presentations/ripe44-rout…
-ris/
Matthew Williams presented the latest status of RIS Project. The RIS Project
is
looking for a new location in Mea-East and Middle-East. There are new
developments like RIS BGP Beacons, RISng, PrefixInuse utility. Also there are
some ongoing projects. MyAS is one of them which allows network operators to
view their AS number in global routing tables. Beyond that, Matthew
presented how DDos attacks on DNS root servers is seen by RIS.
H. RISng - Technical Overview, James Aldridge.
Slides at
http://www.ripe.net/ripe/meetings/archive/ripe-44/presentations/ripe44-rout…
-risng/
James Aldridge gave a technical overview of the new generation of RIS DB.
Running RIS DB has some bottlenecks in central server structure. To sort it
out
a distributed service structure had been developed.
Also James Aldridge presented some graphs which showed how the ms-SQL worm
became visible in routing tables and how it is observed by RIS.

I. BGP Beacon Data and Other Statistics, Henk Uijterwaal.
Slides at
http://www.ripe.net/ripe/meetings/archive/ripe-44/presentations/ripe44-rout…
-beacon/
Henk Uijterwaal presented the analysis he has done by using RIS BGP Beacon
data. Also, he presented the statistics about AS numbers, and Prefixes. One
of
the interesting point in his presentation, one out of 3 ASes is never seen on
routing tables.
Ouestions? Comments.
Christian Panigl: How did Henk produce those numbers like single-home or
multi-homed by looking at the data only IX points? At that point another
question comes up, how much of the Internet is seen by RIS?
Henk Uijterwaal: This is difficult to tell, comparing data with other
Internet
studies and with assigned address space indicate a certain level of
completeness. Much of the global AS topology should be captured, but
definitely
not the majority of local configurations - after all RIS tests only at
certain
sample points in the topology (definition of local?)
Christian Panigl: What happens if a prefix is re-announced before withdrawal
has finished propagating?
This could be tested with RIPE RIS Beacons to find out why route-flap damping
does not work as expected.
Christian Panigl: Is it possible to provide data which architectures do many
withdrawals?
It may be deducted to a certain extent. Regarding version of router operating
systems this is not necessarily obvious.
Wilfried Woeber: RIS does not see the entire picture and because of that it
is
not right to make generalization.
Joachim Schmitz proposed to find out how much of the Internet is seen by the
RIS. Also he suggested to be more careful when phrasing statements about the
status of the Internet, or drawing conclusions on a general level.
Christian Panigl said that RIS is doing a great job.
J. RPSLng, the new draft, Joao Luis Silva Damas.
Joao talked about RPSLng Internet Draft he published last Xmas. There has
been
some discussions about it recently on the mailing lists. The intention was to
publish the second version of the draft before the RIPE meeting but as it
seems
discussion was picking up recently. Joao thinks it's better to publish it
after
the RIPE Meeting in two weeks time. At the same time, the RIPE NCC is doing
preliminary work on implementing the draft.
It is very important to try to implement it before moving on as the
implementation effort would show possible problems in the draft.
Larry Blunk from Merit reports that their implementation is almost ready as
well.
Finally, Joao reports that he submitted the draft as personal draft but
suggests
that successive ones may be submitted from the IETF RP3 WG.
K. Operational Feedback to IP Equipment Vendors, V.Gill.
Slides at http://www.vijaygill.com/nanog26/feedback.ppt
This talk is given by Joachim Schmitz rather than his colleague V. Gill.
If people are interested to learn more, he is reachable at vijaygill9(a)aol.com
Vijay reports on observations during operations and points out problems with
existing router platforms.
Questions?
There was a discussion about in band security, Joachim Schmitz suggested to
take this offline.
Christian Panigl: Is it possible to present which vendors have which
problems?
Obviously, this is of high interest for ISPs.
Joachim Schmitz: Vijay should be able to provide you with any details you
want
Anonymous: These router are core router or not? Is human interaction
considered
or not or config changes?
Joachim Schmitz: The routers studied are at various places of the AOL
infrastructure. For the statistics, errors caused by working on the routers
or changing configurations have been removed.
Anonymous: Equipment ages and this may cause many failures too
Comment: Are you seeing problems caused by any optical components?
Joachim: It is difficult to say. If we are looking at WDM equipment, the
electrical components have a certain failure rate. For the optical elements
themselves (PICs) on the one hand there are not too many vendor options but
so far they have also not shown up as being a particular problem.
Z. AOB
The RIPE NCC announces a new set of courses for LIRs about Routing
Registries.
Additional information is available at http://www.ripe.net/training/rr
It can obviously not be avoided that WGs are running in parallel. Joachim
explains that he knows about substantial overlap with the Database, IPv6,
and EIX WGs. Joachim asked about who sees an impact with other WGs, and it
turns out that the overlap with DNS (counting hands) is also not negligible.
Joachim will work for the next meeting to minimize the overlap.
If anyone has any comment or suggestions, please contact Joachim Schmitz.

Dear colleagues,
obviously, I am a little late in sending this agenda - it has already been
published on the RIPE45 meeting webpage, but here it is anyway... two notes
before that
a) you may want to consider to visit the EOF presentations this time because
they have a focus on several routing related topics (routing table growth,
intro
to JunOS BGP, impact of IX changes on routing, secure BGP) - check out
http://www.ripe.net/ripe/meetings/ripe-45/eof.html for details
b) as you may have noticed this time our two slots are distributed over two
days
- slot 1: Tue, 13-May, 14:00 - 15:30
- slot 2: Wed, 14-May, 11:00 - 12:30
We have distributed the topics a little - Tue has a variety of topics, Wed is
dedicated to BGP related topics. As usual: if you have any comments, sugge
stions improvements - just let us know
----
Tue slot: 13-May, 14:00 - 15:30
Joachim Schmitz: Administrativa (5min)
Larry Blunk: Update on RPSLng (10min)
Steve Kent: What S-BBGP means for RIPE and RIPE Members (20mins)
Dave Cook: soBGP Deployment Considerations (20mins)
The time given includes discussion
Bill Norton: Art of Peering (40mins)
Wed slot: 14-May, 11:00 - 12:30
Philip Smith: A Day in the Life of a BGP Update in Cisco IOS (30min)
Pedro Marques: A Day in the Life of a BGP Update in Juniper JunOS (30min)
Christian Panigl: Experience with Delaying BGP Updates (5min)
Olaf Maennel: Observed properties of BGP convergence (30min)

Dear Colleagues,
[apologies for duplicate postings]
As a service to its members the RIPE NCC offers the
"Routing Registry Training Course".
The main objective of the "Routing Registry Training Course" is to
familiarise the LIRs with the features of the Routing Registry, while
introducing the relevant tools and services of the RIPE NCC. The course
also offers practical exercises.
OVERVIEW OF TOPICS COVERED IN THE COURSE:
- Routing Registry as a part of the RIPE Whois Database
and the Internet Routing Registry (IRR)
- Specifying routing policies using (RPSL)
Routing Policy Specification Language and the RtConfig tool
- IRRToolSet
- Routing Information Service (RIS)
- Routing Registry Consistency Check Project
Please note that this is an advanced course. It will:
- NOT teach the basics of routing
- NOT describe how to receive Internet resources from the RIPE NCC
not describe to operate a Local Internet Registry (LIR)
The target audience of the course are technical staff of LIRs: e.g.
network operators, engineers etc. This course is not intended for
administrative or management staff (e.g. Hostmasters) .
It is assumed that all attendees will be familiar with
Border Gateway Protocol routing and with the RIPE Database
(i.e. creating/modifying objects).
This course is based on interactive exercises in a local network set-up.
Please bring your laptops equipped with the following:
- A working Ethernet card,
- Three meters of Ethernet cable,
- A secure connection client,
- A web browser.
Please be prepared to share your laptop (or at least allow another
attendee to "look over your shoulder") if necessary.
The Routing Registry Training Course is conducted in the English language
and is free of charge, since it is covered by the membership fee.
More information about the Routing Registry Training Course can be found
at: http://www.ripe.net/training/rr/
REGISTRATION:
You can register for a Routing Registry Training Course at the following URL:
http://www.ripe.net/cgi-bin/trainingform.pl.cgi
Or by completing the registration form at the end of this e-mail and
replying to <training(a)ripe.net> .
In order to register for a Routing Registry Training Course you must be an
employee of an LIR and either:
- be an LIR contact
- be confirmed by an LIR contact
LIR contacts are those employees of an LIR who are registered with RIPE
NCC as authoritative contact persons.
It is expected that most of those interested in the Routing Registry
Training Course will not be an authoritative contact person for their LIR,
and therefore will be, refused by the course registration "robot".
In order to be admitted to the course, a confirmation e-mail must be sent
to <training(a)ripe.net>.
Please approach the LIR contacts from your organisation personally,
since the identity of LIR contacts is confidential, and the RIPE NCC is
unable to divulge contact persons for any given LIR.
Kind Regards,
The RIPE NCC Training Team
