This is an auto-generated mail on Fri May 29 12:00:00 PDT 1998 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is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes.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.

RPSL phase ii at RIPE NCC
by Joao Luis Silva Damas 15 May '98

15 May '98

The RIPE NCC is now running a version of the RIPE DB code modified by ISI to support RPSL. The server is running in the configuration specified by Phase II in the "RIPE-181 to RPSL transition plan" (ftp://ftp.ripe.net/internet-drafts/draft-ie tf-rps-transition-02.txt) This phase of the transition plan aims to allow users to get familiar with at least part of RPSL while keeping RIPE 181 as the language in the production database. It is essentially an experimentation phase. (Note: Due to a problem in the interaction between the real-time mirroring in the RPSL version of the code and the production database, synchronization of the two databases is currently done only once a day (during the night). This will be fixed soon. ) Phase ii info ------------- whois host: rpslii.ripe.net port: 43 e-mail updates: auto-rpsl(a)ripe.net (only aut-num objects in phase ii) humans: ripe-dbm(a)ripe.net Updates other than to aut-num objects will fail with the following error message: *ERROR*: unknown object type in RIPE registry Please send questions, comments, etc to ripe-dbm(a)ripe.net Joao Damas RIPE NCC

Looking for sites interested in hosting a test-box
by Henk Uijterwaal (RIPE-NCC) 14 May '98

14 May '98

Dear colleagues, The Test-Traffic Project group is pleased to announce that 20 test-boxes have been built and are ready to be installed at topologically interesting places around Europe. These test-boxes measure the delays on the network by sending time-stamped packets to each other. More information about the Test-Traffic Project can be found on the home-page of the Test-Traffic Project at http://www.ripe.net/test-traffic. If you are interested in hosting a test-box, please start by reading the RIPE documents 168 (version 2.0) and 179, which should contain everything that you need to know about hosting a test-box at your site. Both documents are available from the Test Traffic project home-page. If your site can meet all requirements, please fill out the application form at http://www.ripe.net/test-traffic/host_testbox.html. If anything is unclear or if your site is interested in hosting a test-box but cannot meet all requirements, do not hesitate to contact us. If you have already expressed interest in hosting a test-box, please fill out the form too. It is our goal to distribute the test-boxes amongst topologically interesting places, while at the same time keeping the location of the test-boxes manageable from an operational point of view. Also note that the number of test-boxes is limited and that the project is still in a pilot phase. This means that we may decide that we will not install a test-box at your site even though you applied for one. There is no deadline for applying. We plan to review all applications in the week after Easter (April 12) and let the interested sites know which sites will receive a test-box. We will continue to accept applications until all test-boxes have been installed. Kind regards, Henk Uijterwaal ------------------------------------------------------------------------------ Henk Uijterwaal Email: henk.uijterwaal(a)ripe.net RIPE Network Coordination Centre WWW: http://www.ripe.net/home/henk Singel 258 Phone: +31.20.535-4414, Fax -4445 1016 AB Amsterdam Home: +31.20.4195305 The Netherlands Pager: +6.57626855 ------------------------------------------------------------------------------ %DCL-E-NOCFFE, unable to locate coffee - keyboard input suspended.

11 May '98

Dear colleagues, please find enclosed the draft agenda for the session of the routing working group at RIPE 30, Stockholm. The meeting will be held Tuesday, 19-May, 9:00am Please note that some topics are dealing with RPSL and its implementation. Related presentations are also shown at the session of the database wg on Monday morning. Unfortunately, we were not able this time to organize a separate RPSL session. Therefore, those who are interested in RPSL and its usage might want to visit both the database and routing wg sessions. I would also like to give a few pointers to some resources on the net. If you find the time to look at those pages you are interested in before the meeting you may more easily contribute to the discussion. - on RPSL and its development http://www.ietf.cnri.reston.va.us/html.charters/rps-charter.html http://www.isi.edu/ra/ - on Interdomain Routing Tools and Analysis http://www.merit.edu/ipma/ http://www.rsng.net/pair/ - on IRR security http://engr.ans.net/rps-auth/ This list is definitely not complete but if you follow some of the pointers on the individual pages you will find more... ---- R I P E 3 0 S T O C K H O L M Routing Working Group Session 19-May-98 Draft Agenda A.

Minutes Routing-wg RIPE 29
by Joao Luis Silva Damas 11 May '98

11 May '98

Please find enclosed the draft minutes for the Routing Working Group meeting during RIPE 29 (Amsterdam, 28-30 Jan. 1998) ****************************************************** Draft Minutes: Routing Working Group. RIPE 29 --------------------------------------------- Chair: Joachim Schmitz (JS395-RIPE) Minutes: Joao Luis Silva Damas (JLSD1-RIPE) Attenders: 46 A. Preliminaries (Joachim Schmitz) Joachim Schmitz opened the working group, passed the attenders' list around and asked for a volunteer scribe. Joao Luis Silva Damas volunteered as scribe. 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 28 Action 27.R1: Carol Orange, RIPE NCC To implement cross notification in the RR with modifications as agreed at the meeting of the 27th RIPE Routing WG. Action 27.R2: Carol Orange, RIPE NCC To implement aut-num authorisation in the RR Both actions were still open. The reason for this are the project of rewriting the whole database software, and preparation for the transistion to RPSL. Due to shortage of staff these two actions could not be dealt with. Action 27.R4: Task Force (Tony Barber, Sean Doran, Daniel Karrenberg and Christian Panigl). To write up the results on route flap damping in a RIPE document The final draft of the paper was circulated on the mailing list (see below). This action was therefore closed. Action 28.R1: Carol Orange, RIPE NCC Contact other RR on the topic of distributed authorization Carol Orange met with representatives from other RR (see below). This action was therefore closed. B. Current Developments RIPE Document on Route Flap Damping (Christian Panigl) Input has been gathered from the community, and a report on bugs in the Cisco IOS has been added (regarding improper counting of flaps and early onset of damping). The final draft of the paper was circulated on the mailing list shortly before this RIPE meeting, with a last call for comments. If there are no further additions from the community this final draft will be published as a RIPE document after the meeting (now available as RIPE-178 from the RIPE ftp/web servers). Most of RIPE considerations on route flap damping have been taken into account and put in the internet draft currently being written by Curtis Villamizar, Ravi Chandra, and Ramesh Govindan. However, the scope of their draft goes beyond the RIPE document. Their paper is available from http://engr.ans.net/route-damp/ RPSL Update and Report from IETF 40 (Carol Orange) Unfortunately, there is a delay in implementation of RPSL due to unforeseable circumstances. Nonetheless, implementation will continue, just as other work around RPSL does: - There is a new version of the RAToolset at ISI with partial support for RPSL and there will soon be a new one with full RPSL support. - The RPSL draft has moved to proposed standard. - A draft from David Meyer regarding extension of RPSL was accepted. - A new routing class has been defined providing alternate ways of specifying policy. Another major topic at the IETF was security for the IRR. This arises from the fact that if IRR information is going to be used for configurations on routers, e.g. for filters. The IRR information must be trusted and a clear authorization scheme must exist. The main issues seem to be data integrity, prevention of accidental or malicious misconfiguration and prevention of improper use of adress space. In order to base the BGP filtering scheme on the data in the routing registry, the data must be properly tied to the IP assignment data maintained by the IP registries. In the RPS WG of the IETF where this was discussed, it was noted that this will be more diffucult in the ARIN and APNIC regions where the routing and IP registries are separate. With these requirementes the need arises for communication between IP registries and routing registries. The European internet community has an advantage here. C. IRR Authorization (Carol Orange, swapped in order with Gerald Winters' presentation due to problems with the overhead projector) The goal of IRR authorization is to make BGP routing in the Internet more secure which depends on proper registry data. This is meant to prevent accidental or malicious misconfigurations. Under this prerequisite it is mandatory to define a scheme which allows an ISP to decide which routes they may trust. This calls for a definition of the IRR: A proposal is: "The IRR is a place that reflects what is announced in the Internet and what is permitted to be announced." With AS numbers the path of authority is clear. IANA -> Regional registries -> ISPs This works in Europe but not elsewhere. Actually, it is possible to look for free AS numbers, just use them and register them in the IRR. The authority of AS numbers is not checked by the other routing registries. There have been several occasions when this lead to routing problems. The distribution of IP numbers works similarly. There seems to be agreement in that nonallocated IP numbers should not be routed. However, there is not yet an accpeted mechanism for providing this. One solution could be to delegate authority for a block of IP numbers in the routing registry at the time of IP allocation by creating an object for the full block that can then be subdivided by the ISP. However, this would tie IP allocation to routing entries. Joachim Schmitz noted that people should be aware that this imposes restrictions on what can be registered and is a big change from current practice. Comments on this paradigm shift are welcome. D. Using Internet Routing Announcements to Identify Incorrect IRR Data (Gerald Winters) Most of the results presented here are based upon PAIR. PAIR is the Policy Analyzer of Internet Routing (http://www.rsng.net/pair) One goal is to compare policies stored on IRRs versus real BGP information in real time. Several tools have been developed for looking at announcements - route search tool - route collation tool - AS path analyzer among others. These tools and a few others provide opportunities to identify inconsistencies, and to clean up the routing registries from obsolete or wrong data. The next question arises as to how easy it would be to do this clean up. First it must be known which information should be stored on the IRR. However, this depends on the definition of the IRR. Several have been proposed: - a repository of current internet policy - a repository also for private routing information - a place to experiment In the following, a series of examples of actual objects stored on RADB were shown: - objects with very short prefixes, e.g. 0.0.0.0/1 - private/non routable space, e.g. 10.0.0.0/24 - withdrawn routes several years old - non aggregated (but aggregatable) routes - holes in "non owned" aggregates (either reasonable or mailicious) - registration of all subblocks of an aggregate to prevent the above - extremely old objects - empty policy AS objects (39% of those on RADB) Some of this may look inadequate to some and actually be perfectly reasonable. The question is: What to do with these objects? As a first step a definition for the IRR is required. Any further action can then be based upon this definition. However, to come to this definition consensus must be found that cleaning is needed, and we must define what can be done. The IRR will probably need some power over object removal to clean up data. Yet, the IRR can not decide on its own - community approval is needed. The presentation triggered some discussion. Miguel Angel Sanz asked whether any coordination or contact exists between the different Routing Registries regarding this topic. Gerald Winters replied that RIPE, RADB, and ANS are coordinating, but MCI and CANET are not. Carol Orange added that closer coordination has started recently and is being promoted. There have been discussiones about the authorization scheme. However, we need to take into account that different registries serve different purposes: RIPE and RADB are publicly available but MCI runs a RR for their own purposes. There were remarks regarding the fact that the importance of the correctness of data in IRRs depends on them being used for router configuration and for that to happen better tools are needed. Joachim Schmitz replied that large ISPs currently tend do so and request their peers to do so as well. There were questions regarding the licensing of RADB code and Gated code. Gerald Winters and Jake Kuhon from Merit replied that the funding scheme for Merit is changing right now. Work on Gated has been resumed at Merit. The details on licensing will depend on the final scheme for Merit. Information will be available from Merit soon. Richard Almeida made remarks on the differences in registering procedures between Europe and the US and a general comment on the situation being better in Europe. Questions about followup on aggregation work from previous meeting met the reply there has been no progress recently. E. Reports from other WGs There was no current input from other WGs. F. AOB Since there was no AOB the meeting was closed. Agenda ------ R I P E 2 9 A M S T E R D A M Routing Working Group Session 28-Jan-98 Draft Agenda A.

The Cidr Report

08 May '98

This is an auto-generated mail on Fri May 8 12:00:00 PDT 1998 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.
