[routing-wg]bgpinspect stats fixed...
by Manish Karir 06 Feb '06

06 Feb '06

Just wanted to drop a short to let everyone know that we did fix the annoying bug that was causing the bgpinspect global summary statistics to be zeroes(or inaccurate). These should be working correctly now. I would recommend that people periodically check out the top20 lists. If your AS suddently shows up there in terms of activity, there might be some inherent problem that is responsible for the instability. The "Most Origin AS changes" query results should be taken with a grain of salt, this currently does not correctly account for MOAS behaviour. thanks manish

[routing-wg]Modelling a large ISP network with C-BGP
by Olivier Bonaventure 03 Feb '06

03 Feb '06

Dear All, C-BGP is an efficient and open-source simulation tool that allows to simulate the behavior of the intra- and interdomain routing protocols in large ISP networks. C-BGP is able to simulate networks with thousands of routers. A key feature ofco C-BGP compared to other simulators is that it is able to support the complex routing policies that are used by ISPs. Thanks to the support of France Telecom R&D, we have been able to use C-BGP to reproduce the behavior of BGP in a large Tier-1 ISP network. For this analysis, we have developped several tools to automatically convert the BGP configurations of Juniper (JUNOS) and Cisco (IOS) routers, the IGP topology and the BGP routes in the C-BGP format. With these tools, any network operator can easily build a C-BGP model of his/her network. With such a model, it is possible to perform different types of analysis on the ISP network, such as : - predicting the flow of the traffic through the network or determining the traffic matrix based on Netflow data (see article in January issue of ACM SIGCOMM Computer Communication Review) - predicting the impact of adding a new peering link on the BGP routes selected by the routers (see article in Nov/Dec issue of IEEE Network Magazine) - predicting the impact of link or router failures on the ISP network You can obtain C-BGP, the conversion tools and several papers describing the utilization of C-BGP to model an ISP network or compute traffic matrices from : http://cbgp.info.ucl.ac.be The website also contains several examples, such as a complete C-BGP model of the Abilene Network based on their publically available JUNOS configurations files. We believe that C-BGP could be very useful for ISPs willing to optimise the distribution and the selection of the BGP routes in their network. Comments, suggestions and questions from network operators are more than welcome. Best regards, Bruno Quoitin, Sebastien Tandel and Olivier Bonaventure -- CSE Dept.

[routing-wg]Announce: BGP-Inspect-RIPE
by Manish Karir 23 Jan '06

23 Jan '06

All, I was asked to re-announce our tool to this forum as some people might have missed the original announcement on the nanog mailing list. BGP-Inpsect is a project from Merit Network Inc, and the University of Maryland which provides easy access to archived BGP data from various archives such as Routeviews or RIPE. Uptill now the only data that was available thru our database was a subset of the Routeview data. Additional BGP-Inspect sites are now available as well. This should provide much better visibility than before. The new sites are: - BGP-Inspect-RIPE(http://bgpinspect.merit.edu:9090): Partial RIPE BGP update data, Data from Jan 1 2006 onwards - BGP-Inspect-Merit(http://bgpinspect.merit.edu:8080): Partial Merit BGP update data, Data from Jan 1 2006 onwards The old site was: - BGP-Inspect-Routeviews(http://bgpinspect.merit.edu) Partial Routeviews Data, Data from Aug 1 2005 onwards A new feature that we wanted to announce that has not seen a lot of use is the ability to select multiple "peers" in a single query. This allows you to query for a prefix/AS across multiple peers with a single query. Just hold down the ctrl key to select the peers you wish to query. Usage instructions and some frequently asked questions/answers are available at: http://bgpinspect.merit.edu/faq.php Comments are welcome (offlist please). thanks manish

[routing-wg]routing table growth
by Nikolay Datchev 18 Jan '06

18 Jan '06

Hello group, I want to raise up again the question about world BGP routing table. I don't know what is the result after last discussion (Oct.2005), but maybe peer pressure is not the only way to follow regarding the solution. What a big transit provider can do about customers of it's customer, which politics is "i pay, so i want to do what i want with my AS/prefixes"? I know network administrator, who says "I advertise all my networks as /24's (few /19's...), just because i don't want somebody else to be able to advertise them as more specifics and blackhole me - this is our security policy". There are others, whit PA space, not multihomed, but with own AS number, advertising specific networks just because "it's cool to use my AS number". Or even worse - the combination of the two mentioned above. Also, there are administrators who don't know about aggregating - "I got my 8 class C networks from my LIR, and i advertise them one by one". We have tools like CIDR-repors. Think about this scenario: volunteers spending few hours per week and catching such networks, contacting via email the network administrators, and ask them to aggregate. I have success with this, but only for administrators that i know personally. But i feel inconvenience to contact other people and to say them "Why you don't aggregate your networks? Help for stopping routing table growth!" It sounds sluggish, but it's more than nothing.

[routing-wg]FW: AfriNIC to start allocating from 41/8
by leo vegoda 18 Jan '06

18 Jan '06

Dear Colleagues, The announcement below is should be of interest. Regards, -- leo vegoda RIPE NCC Registration Services Manager -----Original Message----- From: afrinic-discuss-bounces(a)afrinic.net [mailto:afrinic-discuss-bounces@afrinic.net] On Behalf Of Ernest, B.M (AfriNIC - ZA) Sent: 16 January 2006 12:59 To: afrinic-discuss(a)afrinic.net Cc: ioz(a)internet.org.za; afnog(a)afnog.org Subject: [afrinic-discuss] AfriNIC to start allocating from 41/8 Dear Colleagues, As you may be aware, AfriNIC received a 41/8 block from IANA in April 2005. With effect from February 2006, all IPv4 address space allocated within the AfriNIC service region will be made from 41/8. The 196/8 block previously used for allocations in AfriNIC service region will now be used only for direct end-user (PI) assignments. This is therefore a notice that any filters you have may need appropriate adjustments. Kind regards, Ernest, AfriNIC. _______________________________________________ afrinic-discuss mailing list afrinic-discuss(a)afrinic.net http://lists.afrinic.net/mailman/listinfo.cgi/afrinic-discuss

[routing-wg]IRR usage arguments
by Volodymyr Yakovenko 13 Jan '06

13 Jan '06

Hello! I have difficulty in convincing my US colleagues that there are still some autonomous systems in the world which pay any attention to the IRR and sometimes use it for filtering. I also having some difficulty in convincing my collegaues to update the aut-num export statement. They do believe that the folloing statent export: to AS-ANY announce ANY is just enough for all circumstances. I kindly ask you to point me to any examples of autonomous systems which still cross-check periodically import-export policy. I know of at least one such AS, it is AS15645. I also ask for the references to the autonomous systems whose routing policy (strictly) require from its peers a real export policy in the IRR. Any other arguments to the IRR usage are welcome. -- Regards, Volodymyr.

[routing-wg]New IPv6 Address Block Allocated to the RIPE NCC
by filiz＠ripe.net 31 Dec '05

31 Dec '05

[Apologies for Duplicates] Dear Colleagues The RIPE NCC received the IPv6 address range 2A01:0000::/16 from the IANA in December 2005. 2A01:0000::/23 was allocated to the RIPE NCC in July 2005. This latest range includes that previous allocation. You may wish to adjust any filters you have in place accordingly. You can find more information about the IP space administered by the RIPE NCC on our web site at: https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html Regards, Filiz Yilmaz RIPE NCC
