updated routing-wg minutes for RIPE 47
by Joao Damas 28 Apr '04

28 Apr '04

Thanks to Arife Vural of the RIPE NCC for updating the minutes with the comments on the list. Joao Damas Routing wg co-chair ISC -- Minutes of the Routing Working Group held at RIPE 47, Amsterdam, Tuesday, 27th January 2004, 16:00 - 17.30. Session 1: * Administrivia (Joao Damas) Chair: Joao Damas Scribe: Arife Vural, RIPE NCC Attendees: Minutes from R46: No comments -> approved! Actions from R46: None * Call for Participation: Inter-Domain Routing Workshop Inter-Domain Routing Workshop will be held on 1-2 May, 2004 in Amsterdam just before RIPE48. Number of attendees is limited. If you are planning to attend, it's better to sign up as soon as possible. Email list: idrwq(a)ripe.net * Notification on RIPE Routing Registry courses Upcoming RIPE Routing Registry courses can be seen from http://www.ripe.net/cgi-bin/courselist.pl.cgi * RISwhois - mapping IP to ASN using RIS collected BGP data (Rene Wilhelm) A new interface to data collected by RIS project. That allows IP address matching to AS number. Questions: "Are withdrawals and updates are counted?" RIB data is used. "All AS are listed?" Yes "How do you handle AS-set?" It is recorded and it's listed as different objects. * IGP Fast Convergence in a ISP Backbone (Clarence Filsfils) This case study is about the convergence of IS-IS protocol and puts forward some suggestions on how to get a better convergence time. Questions: "Was there propagation delay?" Comeback on few slides. In the study case, we do not have too many hops because of that you do not have much propagation delay. "Which one is prioritized?" /32 is first converged, and then the rest. * Operator Experience from IS-IS Convergence Tuning (Henrik Villfoer) This study is done on the TeliaSonera network. Motivation for such a study is to get a fast convergence time, around 1 sec, for time sensitive new IP services and find the limits of the protocol, IS-IS. Mostly Cisco products are used. Questions&Comments: "How many LSPs were measured after tunning?" More than 100 LSPs. Clarence Filsfils proposed to tune the process-max-time since it should give smaller maximum flooding delays (among other things). There was a comment from audience about the convergence measurement which was done by TeliaSonera: "It would be more interesting if there would be more info about flooding loops." Henrik Villfoer: We actually only measure the number of test packets lost. Systematically inspecting the TTL would tell us if we had transient loops. I could do naught but agree but complemented with the information that manual inspection of a number of cases has shown that loops do exist but are very short lived and uncommon. * IP Fast Convergence Project (Nicolas Dubois / Benoit Fondeviole) France Telecom R&D did this study to how to improve IP convergence in various protocols. Also did study how to solve the problems they had in L2TP tunnels, and MPLS/VPN. Questions: "What do you mean by L2TP is used for INTERNET aggregation?" "When you say you have convergence problems on MPLS/VPN to which kind of problems do you refer?" BGP next-hopt change and NTP. "How does one update make such a change on BGP convergence?" Update to change the FIB. * AOB There is no other business.

Check Your Routing Table! 85-88/8 active
by Daniel Karrenberg 28 Apr '04

28 Apr '04

It is *now* high time to check whether you see the following pilot prefixes: 85.192/16, 85.255.248/21, 86.192/16, 86.255.248/21, 87.192/16, 87.255.248/21, 88.192/16, 88.255.248/21. If you do not see all of these prefixes it is extremely likely that you will have a connectivity problem shortly. We also suggest that you check any packet filters you may be responsible for. Regards Daniel Karrenberg RIPE NCC ------ Notes: This address space has been allocated by the IANA on April 4th 2003, almost a month ago. The fact has been widely announced then. Routing decisions are fully within the responsibility of the network operators. The IANA and the RIRs will only announce which parts of the address space are currently in use. They have no authority whatsoever over routing decisions taken by you and other network operators. More details about this pilot service of the RIPE NCC can be found at http://www.ripe.net/ripe/draft-documents/deboganising-draft.html . A visibility comparison of the pilot prefixes with some production prefixes can be found at http://www.ris.ripe.net/debogon/debogon.html . Those interested in history, see http://www.ris.ripe.net/debogon/ . Pingable targets exist in all pilot prefixes at t{85,86,87,88}-{16,21}.rrc03.ripe.net , i.e. the target within the /21 pilot prefix of 85/8 is t85-21.rrc03.ripe.net . For testing purposes it is possible to do ping and traceroute originating within the pilot prefixes via http://www.ris.ripe.net/cgi-bin/debogon.cgi . Please use this with prudence. More information on how to do Bogon filtering efficiently and reliably can be found at Team CYMRU: http://www.cymru.com/Bogons/index.html

RIPE-229 RIPE Routing-WG Recommendations for Coordinated Route-flap Damping Parameters - Errors/Mistakes?
by Zvezdelin Vladov 27 Apr '04

27 Apr '04

Dear All, I would like to point to you a major mistake throughout this recomendation that might lead to unexpected results, if exactly following the proposed parameters in the RIPE-229. Here they are: 1. At A3.1.1 it is said: "A.3.1.1 For /24s Parameters used are "set dampening 15 820 3000 30" 1st flap 1000 decay to 966, 982 at update 2nd flap 1966 decay to 1894, 1926 at update 3rd flap 2894 decay to 2787, 2846 at update 4th flap 3280 decay to 3165, 3226 at update" Although the comment futher states: "Maximum possible penalty is 3280 as defined by the flap parameters, so the penalty at the 4th flap was only incremented from 2787 to 3280, not 3787 as might have been expected. At the 4th flap the prefix was marked as being suppressed for 59 minutes when the update message was received. If the update after the 4th flap was not received within 4 minutes and 20 seconds, the penalty dropped below 3000, and the prefix was not suppressed." Please note the first line after the A.3.1.1, it is said: "set dampening 15 820 3000 30" And actually it is spoken of dampening parameters such as: "set dampening 30 820 3000 60" Please note the "59 minutes" on the 4th row from the last comment, counting from above to the bootom of the paragpraph. Configuring "15 820 3000 30" gives max penalty 3280, max suppresion time 30 minutes, instead of 60, which is in contradiction with the recomendations made at section 2. of the document. 2.2 Description of recommended damping parameter: Basically the recommended values do the following with harsher treatment for /24 and longer prefixes: * don't start damping until the 4th flap * /24 and longer prefixes: max=min outage 60 minutes 2. On the example configs actually given at http://www.golden-networks.net for the Cisco IOS config, the parameters for /24 are: "set dampening 30 820 3000 60", i.e. the correct values are in the config. So, I suggest correcting this document. One more suggestion is to note the standard dampening parameters for Cisco and Juniper, and especially the different penalty assigment policy - Cisco - on withdraw only, Juniper on withdraw AND readvertisement.

by RIPE NCC Training 22 Apr '04

22 Apr '04

------- 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 teach the basics of RIPE Database operations, - NOT describe how to receive Internet resources from the RIPE NCC - NOT describe how 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 follow ing 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.
