SV: Minutes routing-wg RIPE 47
by Henrik.Villfor＠teliasonera.com 06 Apr '04

06 Apr '04

Hello all, just a couple of clarifications on the questions on my talk as they were quite specific. > > * 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: > > "How many LSP do they have?" More than a hundred. This was a question on a diagram of an "effect on flooding indication" measurement. One of the two curves (the before-curve) contained only about 35 LSPs and the question was how many LSPs were measured in the other. > > "Suggestion tune the closes-max-time." This was a proposal from Clarence, I beleive, to tune the process-max-time since it should give smaller maximum flooding delays (among other things). > > "It would be more interesting if there would be more info about > flooding loops." This was a comment on the convergence measurement we perform since 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. Cheers, Henrik.

Minutes routing-wg RIPE 47
by Joao Damas 05 Apr '04

05 Apr '04

Dear working group, find below the minutes of the routing wg meeting during RIPE 47. My apologies for the late posting of the minutes which were very quickly prepared by Arife Vural, RIPE NCC. The minutes reflect the interaction between the audience and the speakers in response to presentations. See www.ripe.net for the presentation slides themselves. Hope to see you all soon again for a new round of interesting presentations Regards, Joao Damas 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: "How many LSP do they have?" More than a hundred. "Suggestion tune the closes-max-time." "It would be more interesting if there would be more info about flooding loops." * 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.

New IPv4 blocks allocated to RIPE NCC
by RIPE NCC Announcement 05 Apr '04

05 Apr '04

[Apologies for duplicate mails] Dear Colleagues, The RIPE NCC received the IPv4 address ranges 85.0.0.0/8, 86.0.0.0/8, 87.0.0.0/8 and 88.0.0.0/8 from the IANA in April 2004. We will begin allocating from these ranges in the near future. The minimum allocation size for these four /8s has been set at /21. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found on our web site at: <http://www.ripe.net/ripe/docs/smallest-alloc-sizes.html> Additionally, please note that two "pilot" prefixes are being announced from each /8. The prefixes are: 85.192.0.0/16 & 85.255.248.0/21 86.192.0.0/16 & 86.255.248.0/21 87.192.0.0/16 & 87.255.248.0/21 88.192.0.0/16 & 88.255.248.0/21 They all originate in AS12654. More information on this "pilot" activity is available in the draft document "De-Bogonising New Address Blocks" which can be found at: <http://www.ripe.net/ripe/draft-documents/deboganising-draft.html> Best regards, -- leo vegoda Registration Services Manager RIPE NCC
