New IPv4 blocks allocated to the RIPE NCC
by Filiz Yilmaz 05 Jul '05

05 Jul '05

Dear Colleagues, The RIPE NCC received the IPv4 address ranges 89.0.0.0/8, 90.0.0.0/8 and 91.0.0.0/8 from the IANA in June 2005. We will begin allocating from these ranges in the near future. The longest prefixes to be allocated and assigned from these /8s are as follows: IPv4 Range Longest Prefix 89/8 /21 90/8 /21 91/8 /29 You may wish to adjust any filters you have in place accordingly. You can find more information on the IP space administered by the RIPE NCC on our website at: https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html Kind regards, -- Filiz Yilmaz RIPE NCC

AS-set results, new experiments 30/06/2005
by Lorenzo Colitti 24 Jun '05

24 Jun '05

Hi, we have posted preliminary results of our long AS-set announcements to our web site: http://www.dia.uniroma3.it/~compunet/bgp-probing/diffusion.html While we are still working on an in-depth analysis, the results indicate that while the presence or absence of an AS-set in an announcement does have an effect on its propagation, the length of the AS-set, if present, does not have a significant effect. We would also like to move forward with further announcements to determine the effectiveness of our topology discovery algorithms in the IPv4 network. The algorithms, described in our posting a few weeks ago [1] and on the project's web page [2], make use of announcements involving the AS numbers of other ASes to allow ISPs to discover how their announcements can be propagated and how the policies of other ASes in the Internet affect their prefixes. The extensive tests we have performed on the global IPv6 Internet show that our algorithms are effective, but we would like to see how effective they are on the IPv4 Internet given the different operational practices in use. Therefore, starting on Thursday 30 June at 14:00 UTC the prefixes 84.205.73.0/24 and 84.205.89.0/24 will be announced with AS-paths of the form 12654 {...} where the AS-set contains the numbers of neighboring ASes. The announcements will not last more than a few days; as before, should anyone see any problems, please contact me and I will take immediate action. Finally, our tests show that our announcements cause no technical problems; however, if anyone would prefer their AS number not to appear in the AS-sets, and feels that filtering our prefixes is not sufficient, please contact me and we will not use them. Regards, Lorenzo [1] http://www.merit.edu/mail.archives/nanog/msg08501.html [2] http://www.dia.uniroma3.it/~compunet/bgp-probing/ -- lorenzo(a)ripe.net colitti(a)dia.uniroma3.it www.ripe.net www.dia.uniroma3.it/~compunet RIPE NCC Roma Tre Computer Networks research group

Draft minute routing @ RIPE 50
by João Damas 22 Jun '05

22 Jun '05

Here are the draft minutes for the routing working group meeting at RIPE 50, in May. Many thanks to Rene Wilhelm of the RIPE NCC for the fine minutes. Please review them, in particular points C1 and C2 which would require action from the group or at least an expression of opinions Regards Joao Damas ISC ============================= Minutes Routing WG at RIPE50 ============================= Thursday 5 May 2005, 09:00 - 10:45 Chair: Joao Damas Scribe: Rene Wilhelm A. Administrativia - Minutes of previous meeting approved - No open action items on the group B. RIS update - Andrei Robachevsky - RRC13 at the Moscow-IX is online - RRC08 moved to Palo Alto IX and was renamed RRC14 to avoid confusion. - In total 13 remote route collectors with ~450 peers - IPv6 search has been enabled on RIS tools - Beacon experiment continues - myASn is a success, 550 users - Future work items: o Improve RIS db performance o Revisit myASn, consider user use cases, integrate into LIR portal Question: have RIPE NCC thought about using certifcates for authentication, to list the rightfull owner Andrei: we are looking at it, but no planning yet. First are routing security developments, see what happens there, then see what RIRs do Geoff Huston: authentication of resources can have use by itself already, without waiting for routing security. Does the community think this is what RIPE NCC should be doing? Assume RIPE NCC have member certificates, this public key matches that member; as the member has resources, the resources would become extention of the member. You would be saying: RIPE NCC have performed an allocation and that member is the current controller of the resources. When you next go to your upstream and say "please route", you sign with your key and the upstream can check you are the rightfull owner. RFC 3779 as an extension to existing member certificate Andrei: we issue certificates to individuals _representing_ members or to consultants. We cannot devote a lot of resources this year. Gert Doering: usefull task for RIPE NCC to investigate how much work it is, how it can be implemented. It does not effect address policy that much, may need to transfer certificates, but that's mostly technical. Joao: can I have a show of hands, how many are aware of what the discussion is about? [only a small fraction of attendees raised their hand] Let's bring people who can explain certficates, what these are about, how they work. to the next RIPE meeting (october 2005) and continue the discussion then. C. Discussion of topics covered in Philip Smith' talks in the plenary 1. Route Flap Dampening: where to now? http://www.ripe.net/ripe/meetings/ripe-50/presentations/ripe50- plenary-wed-flap-damping.pdf - should RIPE229 be declared obsolete? should it be modified? - is flap damping bad for your network? - needed at the internet edge (=ISPs not providing transit to any other AS) ? - needed in the internet core? Show of hands: how many folk are using vendor defaults, how many RIPE-229? --> RIPE229: most, vendor defaults: few, nothing at all: few Ruediger Volk: a few years ago there was a problem which got solved by damping flapping routes; learning that measures taken can make things worse, we should evaluate if problem still exists. It might be useful to put put something in place to deal with excessive misbehaviour, but you don't want damping to happen in the typical transit provider. Kurtis Lindqvist: flap damping applies to certain networks, certain parts of the world. Add warnings to the document when and when not to use it. Christian Panigl: make it not a real recommendation, but a descriptive document, what damping is good for. Like Ruediger, don't want flap damping happening in the core. Flap damping is bad when it is too agressive. Philip Smith: should we make seperate sections, recommendations to edge providers? recommendations to core providers? And be as descriptive as possible? Iljitsch Van Beijnum (via Jabber): flap damping doesn't work against flapping customers! Christian: it's working as long as BGP itself is stable; if routes behind the session are flapping it works fine. If bgp session itself is flapping you have different mechanisms to find out and obtain statistics. Kurtis: don't put labels, just be as descriptive as possible, if your characteristics match these criteria, take those actions. Ruediger: change the wording, flap damping is an option which has its use in certain places. Documents are now driving things that shouldn't be done. Joao: should anything be done on the status of RIPE-229 now? We cannot change an existing RIPE document, can only publish a new document and make old documents obsolete. Do we wait for next one to be ready before obsoleting the current one? Ruediger: that depends on the timing, if it takes many years to come out with a new document obsolete RIPE-229 right now. If the new document will come out before the end of the year, leave it in place. Christian: can we have volunteers to work with us until the next ripe meeting? [ ... no hands were raised ...] Let's obsolete it. If there are no volunteers to work on it, flap damping is obviously not important enough. Obsolete RIPE-229 and have it in the history archives. Joao: any comments on that? Kurtis: obsoleting the document won't change the problem in the network Joao: at least we would not have wrong information out there Philip: let's see what we can do in the next few months, not everyone is here, let's decide in the October RIPE meeting. 2. Deaggration practices http://www.ripe.net/ripe/meetings/ripe-50/presentations/ripe50- plenary-wed-aggregation.pdf Proposal to introduce a routing-wg work item Aim: document aggregation recommendations for isps Gert Doering: those who participate in the discussion are not the ones leaking all the more specifics. How much good would it do to put out a document? Some folk do it on purpose, knowing it shouldn't be done, ISPs should talk to downstreams not to deaggregate; threaten to depeer if they do not aggregate, or not respond at all. Geoff Huston: Community pressure, address policies no longer seem to work. Proxy aggregation doesn't work very well either; you are not sure if my specifics have leaked around you. Would be nice if market could regulate, currently there are no costs on the poluter. Mike Hughes: LINX members voted the LINX as being a good place for community pressure. Ruediger Volk: going for depeering is not the right level. Keep your own address space highly aggregated. Setup some kind of prefix length routing policy. Other people can point to it, if they are deaggrating don't be surprised if they have less than optimal connectivity because of deaggregation. Need some tools for getting info from the registries? Geoff: the CIDR report is huge, has info for each AS how the announcements compare to allocations Ruediger: have something that rules out /24 deaggration for space out of /20 or /19 allocations already helps Joao: At this time, not much to be done. Pain is not high enough. Geoff: when falling over a cliff, life is fine while falling. D. Discussion about IPv6 BGP filtering BCP (Gert Doering) What sort of BGP filers are usefull for IPv6? slides: http://www.ripe.net/ripe/meetings/ripe-50/presentations/ ripe50-ipv6-bgp-filtering-bcp.pdf Ruediger Volk: max prefixes is a crude heuristic, sometimes there are legitimate reasons for large number of prefixes. Daniel Roesen via IRC: less-specifics don't hurt, only more- specifics can be harmful, so don't filter greater-or-equal. Many IPv6 players out there currently have no real concept of "upstream", "peer" and "downstream" E. Active BGP probing. (Lorenzo Colitti, University of Roma Tre - RIPE NCC) http://www.ripe.net/ripe/meetings/ripe-50/presentations/ripe50- routing-bgp-probing.pdf Lorenzo presents the techniques he and his colleagues at Roma Tre University have developed to help ISPs find out how their prefixes could be announced in case of network faults and how other ASes treat their prefixes. Based on active BGP probing and announcing large AS-sets, these techniques have been successfully tested in the IPv6 Internet. Because of time constraints (the session was already 15 minutes over time) Joao asks those with questions to approach Lorenzo over coffee. =============================

Announcing long AS-sets tomorrow
by Lorenzo Colitti 21 Jun '05

21 Jun '05

Hi, as part of our AS-set stuffing experiments (announced, including links to in-depth information, in [1]), we will be announcing unusually large AS-sets tomorrow, Thursday 16 June. The prefixes involved will be 84.205.73.0/24 and 84.205.89.0/24, both orignating in AS12654. The AS-sets will consist of AS12654 repeated n times, thus the paths will look like 12654 {12654, 12654, ..., 12654}. No other AS numbers will be used. The values of n we will use are 25, 50, 75 and 100. The announcements are designed to discover how far large AS-sets are propagated, and thus how effective our techniques can be, in today's Internet with today's IPv4 operational practices. This is *not* a test to see if routers will fall over: we have successfully tested longer AS-sets in the lab on both Cisco and Juniper, and longer AS-paths and AS-sets have been observed in the wild [2,3].
