Announcement Routing Registry Training Courses
by RIPE NCC Training 17 Dec '03

17 Dec '03

------- 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 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, Training Team RIPE NCC ************************************************************************* COURSE DATES AND VENUES ======================== Date: Friday 6 February 2004 Time: 0900 - 1700 Location: Amsterdam, The Netherlands AND: Date: Tuesday 17 February 2004 Time: 0900 - 1700 Location: Tehran, Iran AND: Date: Friday 5 March 2004 Time: 0900 - 1700 Location: Rome, Italy AND: Date: Friday 23 April 2004 Time: 0900 - 1700 Location: Istanbul, Turkey AND: Date: Friday 14 May 2004 Time: 0900 - 1700 Location: Bratislava, Slovakia AND: Date: Thursday 24 June 2004 Time: 0900 - 1700 Location: Stockholm, Sweden ************************************************************************* REGISTRATION FORM ================= %START PART 1 - Registration 1) Your name Enter First name, Last name in full e.g. John Doe Mary-Beth Walton # NAME [ ] 2) Your Registry ID (format: country-code.<name of registry>) # REG [ ] 3) Your e-mail address # EMAIL [ ] 4) Your NIC handle (optional) # NICHANDLE [ ] 5) The course you plan to attend (date and location) # COURSE [ ] %END

survey on BGP damping
by Beichuan Zhang 13 Dec '03

13 Dec '03

Hi, We are conducting a survey of BGP damping deployment and would greatly appreciate if you could take a few minutes to answer the following questions. There are a number of interesting results and various recommendations for damping settings. However, we have found only limited information on who does(does not) deploy damping and what parameter settings are selected in practice. If you are willing to participate, please send replies directly to us. We will collect the results (removing any private information regarding specific sites) and post the results to the list. Thanks! --- beichuan (1) Does your AS have BGP route flap damping turned on? * Yes * No (please skip to comments) (2) What damping parameters do you use? * Cisco Default * Juniper Default * RIPE recommendation * Customized (3) On which links do you enable damping? * To customers only * To providers * To peers * All the above (4) Comments Please tell us more such as: What kind of network are you managing (any specific names will be removed in the published study)? Why (why not) do you enable damping? If you enable damping, why did you choose your current parameters? Has your site seen specific problems that were prevented by damping (or caused by damping)? We welcome any other comments you feel are relevant. Thanks!

New Statistics Format Released
by Shane Kerr 09 Dec '03

09 Dec '03

Dear Colleagues, The RIPE NCC has been working with the other Regional Internet Registries (RIRs) - APNIC, ARIN, and LACNIC - to provide Internet number resource statistics in a common format and location. The RIR Statistic files summarise the current state of Internet number resources, and are intended to provide a snapshot of their status without transactional or historical details. The following changes will be made to the existing statistics files: - Addition of IPv6 allocations - Addition of Early Registry Transfer (ERX) IPv4 networks - Addition of Provider Independent (PI) assignments - MD5 checksum provided for verification - New directory - Minor changes in format The statistics in the new format are available at: ftp://ftp.ripe.net/pub/stats/ripencc/new/ And the statistics in the current format are available at: ftp://ftp.ripe.net/pub/stats/ripencc/ The RIPE NCC will continue to produce the statistics in the current and new format until 5 January 2004. On this date, the statistics will be in the new format at: ftp://ftp.ripe.net/pub/stats/ripencc/ Statistics previously generated will be available at: ftp://ftp.ripe.net/pub/stats/ripencc/old/ Documentation of the format of these files may be found at: ftp://ftp.ripe.net/pub/stats/ripencc/new/RIR-Statistics-Exchange-Format.txt -- Shane Kerr Software Engineering Department Manager RIPE NCC

Deprecation of "cross-nfy:" and "cross-mnt:" attributes in the RIPE Whois Database
by Katie Petrusha 06 Dec '03

06 Dec '03

[ Apologies for duplicate messages ] Dear colleagues, "cross-nfy:" and "cross-mnt:" attributes will be deprecated in the RIPE Whois Database by 1 February 2004. The RIPE Whois Database previously had a cross notification mechanism. This mechanism used "cross-nfy:" and "cross-mnt:" attributes of route and aut-num objects to notify particular maintainers and contacts when an overlapping route object had been added or removed. In May 2003, this mechanism was deprecated, as it is already covered by Routing Policy System Security functionality. In March 2003, the proposal was circulated to deprecate "cross-nfy:" and "cross-mnt:" attributes in the RIPE Whois Database as they are no longer needed: http://www.ripe.net/ripe/mail-archives/db-wg/2003/msg00035.html Approximately 180 aut-num and 620 route objects will be affected by this change. These objects should be modified before 1 February 2003 and the "cross-nfy:" and/or "cross-mnt:" attributes should be removed from them. As soon as these attributes have been deprecated, they will not be accepted in the RIPE Whois Database. Therefore, we encourage everyone to make the necessary modifications in advance. The RIPE Database Administration will update the objects still requiring modifications to change deprecated attributes into "remarks:" attributes. No individual notifications will be sent. Relevant maintainers will be notified via the usual RIPE Whois Database notification mechanism. This information can be found at: http://www.ripe.net/db/cross_nfy_mnt_deprecation.html -- Katie Petrusha Software Engineering Department RIPE NCC
