less than a /24 & BGP tricks
by neal rauhauser 30 Jun '09

30 Jun '09

I have a network with two upstreams that land in datacenters many miles apart. The hardware involved is Cisco 7507s with RSP4s and VIP4-80. I've got a curious problem which I hope others here have faced. A while ago we got a /28 from each provider and attached it to a dedicated fast ethernet interface at each location. Inbound traffic arrives normally and anything arriving on that port is policy routed to the upstream that provided the prefix. This was all well and good when it was a little firewall with a Linux machine behind it being used to check latency and do other diagnostics, but the sales people noticed it and have lined up a couple of opportunities to sell a service that would depend on our being able to receive and send traffic from blocks less than a /24. The policy routing works fine at low volume, but the RSP4 is rated to only do four megabits and I know they're going to exceed that. I can terminate this subnet on another router, wire that device into the 7507 with a crossover, and establish a BGP session. I'm wondering if there is a tidy way to set next hop in some fashion using route-maps such that all the marking would be done on the auxillary machine and the traffic passing through the 7507 would be CEF switched rather than process switched. -- mailto:Neal@layer3arts.com // GoogleTalk: nrauhauser(a)gmail.com IM: nealrauhauser

Reduced ISP uptime after BGP annoucement
by Dylan Ebner 30 Jun '09

30 Jun '09

My company started partial BGP annoucements several months ago with our primary ISP, Qwest, and ever since BGP went active we have had more Qwest downtimes in 3 months than we had the previous 5 years. All of the downtimes have been within the qwest DIA group and not the deliver compenent group. Does anyone know if it is the policy of Qwest (or ISPs) to have lower uptime metrics for BGP customers or am I just experiancing lots of downtime with an ISP that is known for having lots of problems? Thanks Dylan

question about Mark Koster's ARIN presentation
by sandy＠tislabs.com 29 Jun '09

29 Jun '09

This message is sent to the whole nanog list, rather than the nanog-attendees list, as I'm not sure who would be watching that list when the conference is over. I stood up to ask a question at the end of Mark Koster's presentation yesterday, but before I got to the end of the table, he was being applauded and leaving the stage. I must be too short. The presentation said that ARIN would be doing a lot of work to improve the IRR. The last I asked, the ARIN IRR did not support the RPSS (Routing Policy System Security - RFC2725). RIPE supports this, I know. Will the ARIN improvements include support for RPSS? The presentation talked about the RPKI pilot, and Mark said that ARIN would be using the RIPE code. I believe RIPE has or had a couple different attempts at this, so I'm not sure what features the code you use will have. Will you have the ability to hand certs to ISPs so that they can do their own cert generation for the allocations they hand to their own customers? I.e., is ARIN going to run a service just for its members, or will it enable its members to participate in the RPKI themselves? --Sandy

ops cabal dinner experiment
by Randy Bush 29 Jun '09

29 Jun '09

as discussed in philly, and with encouragement of ops AD, ... if and only if you are an actual real live operator, i.e. have hands on routers of a non-trivial isp, or a non-trivial server farm, and will be at the stockholm ietf, we are planning an informal operators' dinner to discuss ops issues and agendas for the week's meetings. it would be sunday eve the 26th. maybe rsvp privately so i can get an idea of scale. feel free to include any issues you think important, so we can start an agenda. randy

ISP best practices
by Philip Lavine 28 Jun '09

28 Jun '09

To all, I am sure this has been asked 10 to the 1 millionth power times, however may be the rules have changed. I am looking to set up a really small ISP with a few /24's. I want to host DNS as well. Is there any whitepapers/howtos/best practices on setting up multihomed BGP and DNS with BIND so I don't blow up the Internet. Thx Philip

Flow Chart
by Alexandre Augusto Caramanti Coconesi 28 Jun '09

28 Jun '09

Hello This is my first post in this list. I have the follow situation: I have a multilateral peering, and I´m need to plot a graph showing how many traffic is going to or comming from each member of peering. For example: I have the AS61222, and in the peering there is the AS61333. This AS have other peerings, And my AS (AS61222) use the AS61333 as transit. And because it is a peering, by just one interface of my router, I can see just the whole traffic, to AS61333, and another members of peering. I was seeing some thing in JKFlow, but I did not found any thing. Do you have any experience in a case like this? Thanks -- Alexandre Coconesi

Security Assessment of TCP at the IETF
by Fernando Gont 27 Jun '09

27 Jun '09

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Hello, folks, In February this year the UK CPNI published the document "Security Assessment of the Transmission Control Protocol (TCP)" (available at: http://www.cpni.gov.uk/Docs/tn-03-09-security-assessment-TCP.pdf) Earlier this year we published an IETF Internet-Draft version of this document (available at: http://www.gont.com.ar/drafts/tcp-security/draft-gont-tcp-security-00.txt) in the hope of having the IETF further work on the TCP security paper UK CPNI had published. My personal take (possibly biased, since I am the document author) is that this document has been the result of a lot of work (including the work of the many peple that reviewed the CPNI version of the document), and that the IETF should take this chance to work and publish something on the subject. The chairs of the TCPM Working Group of the IETF are currently polling the WG for input about this document. It would be great if you could voice your opinion about whether the TCPM should take this document on, and also whether you would be willing to review this document. (Bellow you'll find a copy of the TCPM chairs' poll) Please send your comments to tcpm(a)ietf.org (and please CC me). Thanks! Kind regards, Fernando - -------- Original Message -------- Subject: [tcpm] poll for adopting draft-gont-tcp-security Date: Wed, 24 Jun 2009 14:25:04 -0500 From: Eddy, Wesley M. (GRC-MS00)[Verizon] <wesley.m.eddy(a)nasa.gov> To: tcpm Extensions WG <tcpm(a)ietf.org> TCPMers, there was a thread a while ago about working on draft-gont-tcp-security in this working group that didn't conclusively give us a feeling one way or other: http://www.ietf.org/mail-archive/web/tcpm/current/msg04489.html Basically, my understanding is that there are at least a handful of people in the WG that think it should be done here as a WG item (more likely for Informational rather than BCP), and there are also some expressed opinions on why it shouldn't. Given the raw size of the document, if the WG intends to take this document on, then we need some people to clearly commit to putting cycles into review and contributions to the document. Since it is quite large, and to my knowledge, there hasn't been a specific technical review of the content on this list, but just discussions about if the idea in general is a good or bad thing, we still need to know if people are willing to invest their time and energy in this. Please let us know if there is traction for this in the near term, and/or we can also discuss it in Stockholm. - --------------------------- Wes Eddy Network & Systems Architect Verizon FNS / NASA GRC Office: (216) 433-6682 - --------------------------- _______________________________________________ tcpm mailing list tcpm(a)ietf.org https://www.ietf.org/mailman/listinfo/tcpm - -- Fernando Gont e-mail: fernando(a)gont.com.ar || fgont(a)acm.org PGP Fingerprint: 7809 84F5 322E 45C7 F1C9 3945 96EE A9EF D076 FFF1 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (MingW32) iQEcBAEBCAAGBQJKRngWAAoJEJbuqe/Qdv/xn7AIAMeN8Yz3JeAC+WIbThkBK7Xe D/kRdi6mO7ffX2etNPec4vlgbrzkjnef3PTB6GGrJGkyACm/J/NuMEj/1k8GqqtS 7byVkfTQSDsm64e44el4A6tqGlxw/GnRagK5I9VpC8PvTeLuhAxCuMhblhpeZQyD SdnOInqxXYg57FDXPWq1bWIvNWZ8xUAAmAbE5ppSOYBGUoG5jua4ONGDdo5FYvpz ABvVF1lKds+4dGimGjEHH10OIaVhHvuxIX2IIsG0REBHkK3z/Pij7+RvrrlsIRLS R0rvgCL78nQCvyYYiepcKpMrL6iEe3YP4RlVfTgnhKI+a3qZo0TFTSjheuh6Bmg= =6b3p -----END PGP SIGNATURE-----
