Accessing Routing Information Via RIPEstat
by Vesna Manojlovic 23 Aug '13

23 Aug '13

Dear colleagues, (apologies for cross-posting) Our Routing Information Service (RIS) has been collecting global BGP routing information for 12 years now. During this period, many different interfaces to analyse and visualise accumulated data have been developed. In line with our long-term goals to provide more consolidated services, we will be integrating the RIS interface's tools and services into RIPEstat. More information about this is detailed in a new RIPE Labs article: https://labs.ripe.net/Members/fatemah_mafi/improved-routing-information-ava… We invite the community to comment on these upcoming changes via the MAT Working Group Mailing List: https://www.ripe.net/ripe/groups/wg/mat Please submit any urgent requests for additional features via email to stat(a)ripe.net by 20 September 2013 so that we can implement these along with the planned migration of tools and features. Any feedback received after this date will be considered feature requests, and added to the RIPEstat Roadmap: http://roadmap.ripe.net/ripe-stat/ We look forward to your feedback. Regards, Vesna -- Vesna Manojlovic BECHA(a)ripe.net Senior Community Builder @Ms_Measurements for Measurements Tools RIPE NCC http://ripe.net

Re: [routing-wg] Network failed [was re: Notification of RIPE Database changes]
by Denis Walker 23 Aug '13

23 Aug '13

Dear colleagues, Apologies for the delay in replying. It took me a while to find the time to write this article. I have written a RIPE Labs article explaining the background of how the RIPE Database works as an open, global Internet Routing Registry: https://labs.ripe.net/Members/denis/using-the-ripe-database-as-an-internet-… The article outlines the different scenarios, which explain how the reported situation occurred. I also raised a few questions in the article that I have heard whispered over the years. Perhaps it is time to review how this aspect of the database works. I also wrote an email to the Address Policy Working Group recently outlining the can/can't do list of actions regarding the aut-num object, which may be of interest in this discussion: http://www.ripe.net/ripe/mail/archives/address-policy-wg/2013-August/008174… Regards Denis Walker Business Analyst RIPE NCC Database Team

new RPSL import-via/export-via attributes in aut-num Class
by Job Snijders 14 Aug '13

14 Aug '13

Dear Routing working group, As some of you might know I've been working on extending the RPSL syntax to make life easier for certain scenario's, such as operating a Route Server. Below is the message I've posted in db-wg(a)ripe.net, and I suggest we discuss this in the db-wg@ to keep the conversation central. - Job ------------------------------------------------------------ The purpose of the new attributes and the patch is to make life easier for Route Server operators whom have to deal with participants who have been assigned a 32 bit ASN. There currently is no way to relay information between non-adjacent ASNs, and 32 bit ASNs do not fit into standard BGP communities when coupled with an action code. Often Route server operators overload BGP communities to assess which participant should receive what prefixes, the "via" feature addresses exactly that concern. I have submitted the following draft to the IETF: http://tools.ietf.org/html/draft-snijders-rpsl-via And I have submitted a patch for the RIPE whois server to support the feature. https://github.com/job/whois The extension should be backward compatible with minimal impact on existing tools and processes, following Section 10.2 of RFC2622. RPSL parsers which do not understand the new attributes are expected to just ignore it. I am looking for feedback from this community, and especially the community's blessing to allow RIPE NCC to adopt the patch. Kind regards, Job

Fwd: [address-policy-wg] Draft proposal: Guidance Requested: Reassigning Referenced ASNs
by Rob Evans 14 Aug '13

14 Aug '13

All, you might be interested in this, it is how the RIPE NCC plan to deal with removing references to reclaimed ASNs in database objects (e.g. RPSL routing policies). Cheers, Rob Begin forwarded message: > From: Ingrid Wijte <ingrid(a)ripe.net> > Subject: [address-policy-wg] Draft proposal: Guidance Requested: Reassigning Referenced ASNs > Date: 14 August 2013 09:47:37 BST > To: address-policy-wg(a)ripe.net, db-wg(a)ripe.net > > Dear colleagues, > > Thank you for your feedback on this issue. Based on the input we have received we propose taking the following action: > > - The RIPE NCC will send an email to the maintainer and contacts of the RIPE Database objects in which the returned AS numbers are referenced, asking for the reference to be removed. > - The RIPE NCC will send three additional reminders, at intervals of three weeks from each other, for a total of four emails. > - If after four emails the reference is still in place, the RIPE NCC will update the RIPE Database object itself, removing the reference. > - If the reference is being recreated within one month from deletion (possibly due to automatic updates), the RIPE NCC will contact the organisation through means of communication other than email. > > The total number of RIPE Database objects that reference returned AS numbers is currently about 2000. All references are in the policy attributes of aut-num objects. No route(6) objects are involved. > > Thank you again and best regards, > > Ingrid Wijte > RIPE NCC >
