ANNOUNCEMENT: ROUTING REGISTRY TRAINING COURSES
by RIPE NCC Training 20 Dec '02

20 Dec '02

Dear colleagues, [apologies for duplicate postings] As a new service to its members the RIPE NCC offers the "Routing Registry Training Courses". 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, nor 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 BGP routing and with the RIPE DB (creating/modifying objects). This course is based on interactive exercises in a local network set-up. Please bring your laptops equipped with: - Working Ethernet card, - 3 meters of Ethernet cable, - Secure connection client, - 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 contribution. More information about the Routing Registry Training Courses can be found at: http://www.ripe.net/training/rr/ REGISTRATION: You can register for a 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 email 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 persons for their LIR, therefore will be refused by the course registration "robot". In order to be admitted to the course, confirmation email need to be send 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.

RE: Route update stats

Karsten, thats really an interesting question: ACOnet receives a full routing-table from SPRINT/AS1239 and from GEANT/AS20965. Comparing the current BGP session counters: neighbor SPRINT, uptime ~20weeks, Received 7926940 messages neighbor GEANT, uptime ~ 7weeks, Received 29597194 messages which gives a long-term average of 419 BGP update messages per minute from GEANT but only 39 BGP update messages per minute from SPRINT afaik GEANT does no BGP flap damping, SPRINT however does, according to http://www.sprint.net/policy/bgpdamp.html I don't know if damping is the only reason for the factor >10 between them, there might be other reasons as well, e.g. SPRINT backbone is Cisco based, GEANT is Juniper based and they might be using completely different IGPs and iBGP concepts. I am also suspecting some improperly behaving BGP implementations beeing around, e.g. at the VIX we are having peering neighbors who are sending superproportional more BGP updates than others with the majority of the messages beeing withdrawals for prefixes which they do not own nor announce. Btw, Lambdanet is sending us a long-term average of 2 BGP update messages per minute at the VIX.

Seems unlikely. But, if the 80/20 rule applies (80% of activity is created by 20% of the prefixes), then you'd expect 20000 prefixes to generate around that many announces/withdraws. BTW, 2.1k is about 2% of 110k ;-) This adds weight to your argument rather than diminishing it... Regards, Guy This e-mail is private and may be confidential and is for the intended recipient only.

Thanks Guy, here we go: 115599 prefixes from SPRINT 117736 prefixes from GEANT 2137 difference (~5%) I can't believe that those 5% are making 380 update messages per minute !? But of course this might be one part of the +update messages. Regards CP

It could also be due to the fact that SPRINT certainly constrains (or used to constrain) the maximum prefix length it will accept (not longer than /24 - used to be /18 I think but that was way too restrictive). Don't know about GEANT? Logically, you'd expect smaller blocks to be flapped more than larger aggregates so removing the smaller blocks entirely from what you accept/announce would reduce the number of announcements/withdrawls you make (even taking flap damping into account). It might be worth looking at the relative size of the "full" routing tables you receive from SPRINT and GEANT. If it's more from GEANT, that might be the answer.
