22 Jan '99

This is an auto-generated mail on Fri Jan 22 12:00:00 PST 1999 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.

Draft Minutes: Routing Working Group. RIPE 31 --------------------------------------------- Chair: Joachim Schmitz (JS395-RIPE) Minutes: Miriam Kuehne (MK16-RIPE), Julia Edwards (JE316-RIPE) Attenders: 99 A. Preliminaries (Joachim Schmitz) Joachim Schmitz opened the working group session, passed the attenders' list around, and asked for a volunteer scribe. Miriam Kuehne volunteered as scribe. During the session Julia Edwards took over. The working group agreed upon the minutes of the previous meeting, and accepted the draft agenda earlier circulated on the mailing list. Review of actions RIPE 30 o 29.R1 G.Winters, J.Schmitz, RIPE NCC Definition of the IRR and an AUP -in progress- Gerald Winters is giving a presentation in this session on work done so far on this topic o 29.R3: RIPE NCC, JLS Damas Implementation of PGP -to be closed- The action may be considered closed because it will be moved to beta in the next two weeks o 30.R1: RIPE NCC, JLS Damas Implementation of autnum authorization -postponed- Implementation has been postponed because this is one special feature within the more general scope of the RPS Authorization draft o 30.R2: RIPE NCC, J. Schmitz, W. Woeber Organize RPSL tutorials for RIPE 31 -done- The RPSL tutorial has been held. B. Report from the RPSL Tutorial - (Joachim Schmitz) RPSL is the "Routing Policy Specification Language" developed by the IETF RPS Working Group. For those who are not familiar with this topic the following pointers may be of interest: http://www.ietf.org/html.charters/rps-charter.html http://www.isi.edu/ra RPSL is in the stage of deployment phase 2 with the final transition phase from RIPE-181 in sight. Part of the transition is education to make it easier for users to apply RPSL. After some tutorials in the US we had the first RPSL tutorial in Europe just prior to this RIPE meeting. There were approximately 90 participants. The training materials are available electronically at http://www.isi.edu/ra/rps/training Future tutorials will be held at the next RIPE meeting, and plans to offer them as part of the LIR tutorials are currently considered. Joachim Schmitz then thanked the trainers Cengiz Allaetinoglu, David Kessens, and the RIPE NCC, for preparing and performing this tutorial. C. Report from the RIPE NCC (Joao Luis Silva Damas) (http://www.ripe.net/meetings/ripe/ripe-31/pres/ncc-upd/index.html) The report included a general update on NCC activities. In the database software, cross notification was added, making use of the two tags "cross-nfy" and "cross-mnt". The functionality follows the specifications developed by the Routing WG in earlier sessions, both regarding the notification in relation to "autnum" and "route" objects. In addition, PGP authentication will also become available in approximately two weeks for production after this RIPE meeting. This method is supplied in parallel to "none", "e-mail address", "UNIX style password", but offers significantly better security. This method may currently be tested at queries: beta-whois.ripe.net submissions: auto-beta(a)ripe.net in beta status. The implementation follows the Internet draft http://www.ietf.org/internet-drafts/draft-ietf-rps-dbsec-pgp-authent-00.txt developed in the RIPE Database Security Taskforce, and written up by its members Janos Zsako. D. Reports on RPSL Deployment at Registries o RIPE NCC (Joao Luis Silva Damas) (http://www.ripe.net/meetings/ripe/ripe-31/pres/routing-wg- rpsl/index.html) Phase II of the transition has been completed, meaning that a mirror of the production database is installed and running. The mirror according to definition of transition phases is one-way only (RIPE-181 -> RPSL). The phase II database is accessible at - rpslII.ripe.net - auto-rpsl(a)ripe.net Submissions in RIPE 181 format are still possible and will be translated into RPSL. At the same time straight RPSL submissions are possible. Only autnum objects are currently handled in RPSL format. The database is running using ISI's code written by David Kessens. The usage is still low (which is no wonder because the server just became available). In the future, as part of the database reimplementation, the RPSL capable database will support the full set of RPSL features, and also support the RAToolSet. o ISI (David Kessens) There are three phases proposed in the transition from RIPE-181 to RPSL: phase 1: software development done phase 2: tool development, testing, training real time mirror of IRR in RPSL format special RPSL update path for "autnum" objects *status of today* phase 3: switch over incoming RIPE-181 objects are automatically converted to RPSL during 1999 RIPE, ANS, and Merit are currently in phase 2. MCI and CANET are testing RPSL software. Telstra moved to RPSL, and Connect (AU) is already configuring their routers using the alpha RAToolSet for RPSL. A set of others is know to evaluate. Regarding training and education the following tutorials were held so far - Jun 1998, NANOG in Detroit - Sep 1998, Ripe-31 Edinburgh - Mar 1999, APNIC, Apricot (planned) To make use of RPSL, the following software is available: - RAToolSet - RIPE database with RPSL extensions which is compatible to RIPE db 2.1.3. The full RPSL support will move to beta soon. - R181 to RPSL database objects converter The software is available at http://www.isi.edu/ra/rps/transition o RADB (Gerald Winters) Merit offers a public RPSL server rpsl.merit.edu 43 since spring/summer 1998. Usage is on the rise, and comments from users are focusing on two items - why is the system rejecting my AS object - here is a bug I see In Gerald's personal opinion, a large number of RADB users has not yet logged on to the RPSL server because - the old software works and still seems to satisfy their needs - a steady influx of users exist who do not know RPSL - there is a group of "regular" registry users who think the ISP will do it all Therefore, Gerald lists the following suggestions: - continue the current education strategy - include informative footer messages in email transaction responses - I do not see things as bleak - registry admin's will certainly be putting in extra email consulting hours. Usage and involvement by ISPs at this time is not much. Most of it comes from specialists, or users already interested having discovered the potential in RPSL. Usage outside the US, especially in Europe is still low. It is obvious that more training is needed, and work to make it more useful. Users will definitely change their attitude if usability is better. E. Do we need a Routing Registry for IPV6? (Joachim Schmitz) (http://www.ripe.net/meetings/ripe/ripe-31/pres/ to come soon) In the introduction, a short review was given of what currently is part of the IPv4(!) routing registries, and what benefits its users have from it. It is obvious that today no IPv6 registry exists, and the question was raised whether on is needed. Then the current situation regarding IPv6 was described, and the expected development of IPv6 "Inter6net" with its interaction towards IPv4 listed. Looking at the benefits the IPv4(!) IRR offers, it seemed obvious that they are also applicable to an IPv6 routing registry. Consequently, the conclusion was drawn that a need for an IPv6 routing registry exists, which may even add more value by easing the coexistence of IPv4 and IPv6, and may help in transition to IPv6. The time to raise the topic is not too early because during the 1st quarter of 1999 the IPv6 address allocation is likely to begin. The presentation was finished with a call for participation to explore the idea and to define the requirements. F. An AUP for the IRR (Gerald Winters, Pierre Thibaudeau, Joachim Schmitz) The authors feel that a need exists to build an acceptable use policy for the IRR. To start with the question was discussed what an AUP is. It may simply be defined as a document which lists acceptable IRR practices and data, covering topics for the users like - what purposes should the IRR be used for? - what types of data would I register? - Are there important relationships between objects I should be aware of? - Can I find suggestions for maint. my data? The goals of the AUP may be summarized as - add value to the IRR - address the concerns of (the user and db admin) - provide an easy to understand single point of reference - prevent abuse The AUP may then be used - as reference point, especially for new users - by registry admins signing the AUP to declare the data as conformant with it - by users (eg, comparable to the implied consent from the RIPE copyright in the RIPE.db) The AUP is still under development. The work on it is not yet complete, and some of the suggestions require further detailed discussion. The talk was given to make the community aware of the AUP, to solicit feedback, and to ask for support. The IRR AUP will definitely acknowledge other efforts. Others are currently defining relevant policy rules or have already done so - RPS (rps-auth) - RIPE NCC - Merit Some of the ideas to follow overlap or duplicate existing policies. This is not a bad thing, and it shows consistency with out goal to provide a single point of reference. In the following part of the presentation, a starting framework for an AUP was shown: - Contact information should be kept up to date "Contact information is important data which facilitates communication between network parties. Therefore it is encouraged to keep role and person object data up to date as well as all tech-c and admin-c references." - Commercial uses of the IRR "All commercial uses are stricly forbidden. Contact information must not be used for commercial purposes, advertising purposes, or any other purpose beyond the scope of activities relating to the successful operation of the Internet." - Old objects Old objects are a matter of concern. They are not necessarily invalid. However, current does not imply up to date. So aging out objects based on a "changed:" time stamp (even machine generated) is a probably a bad idea. Using global routing data with IRR information is a better solution. A suggestion may build on read time stamps, because it shows that even old data is still accessed, and therefore most likely still valid. Yet, it must be explored whether this approach is practical. Obviously, there is a series of items which needs further discussion. This includes the concept of cross notification and whether it is recommendable or not. The following discussion did not very much enter this area but focused on the abuse of data in the registry, including contact information by spammers, reluctance of service providers to disclose their policies (company policy and possible business impact), and security of data in the database. G. Routing Policy System Security (Cengiz Allaettinoglu) Due to time constraints the presentation on this topic was moved to the Database Working Group session. Joachim Schmitz apologized to the Cengiz, and thanked Wilfried Woeber for accepting the transfer. Y. I/O with other WGs The presentation on whether a Routing Registry for IPv6 is needed was also given as input at the IPv6 Working Group. Z. AOB There were no additional comments or issues.

RIPE NCC PGP license distribution
by Joao Luis Silva Damas 20 Jan '99

20 Jan '99

Dear all, as you may be aware from past presentations at RIPE meetings and discussions in the lists, the RIPE Database now supports PGP authentication as a stronger way of protecting your database objects. This use of PGP with the RIPE Database is seen by PGP Inc as a commercial use of their software that therefore requires a commercial license. To enable users to take advantage of the new feature, the RIPE NCC will distribute PGP licenses to Database users according to the policy and procedures described in a new RIPE Document: RIPE 190, available now at the RIPE NCC's website. http://www.ripe.net/docs/ripe-190.html To obtain more information on how to use PGP with the RIPE Database, please refer to the recently release RIPE 189 document, also available at the RIPE NCC's website. http://www.ripe.net/docs/ripe-189.html Please direct any questions/comments to ripe-dbm(a)ripe.net Best regards, Joao Damas Database Group RIPE NCC

As far as I see from current planning (not yet on RIPE web site) the MBone session comes after the Routing WG session. So we will not have a clash if we share the topic. However, I would like to suggest that in order to properly deal with the topic that we take this as input to the Routing WG. I would then require a short presentation from you - if someone is interested to give a sketch of the ideas (no solutions yet; they still need to be developed, obviously ;-) I greatly appreciate it. Please write back to me for proposals. Thanks a lot Joachim --- JS395-RIPE -- standard disclaimer ---
