2018-06 Discussion Phase (RIPE NCC IRR Database Non-Authoritative Route Object Clean-up)
by Marco Schmidt 05 Jun '19

05 Jun '19

Dear colleagues, A new version of RIPE Policy proposal, 2018-06, "RIPE NCC IRR Database Non-Authoritative Route Object Clean-up", is now available for discussion. The goal of the proposal is to delete an non-authoritative object stored in the RIPE IRR, if it conflicts with an RPKI ROA. The proposal has been updated following the last round of discussion and is now at version v2.0. Some of the differences from version v1.0 include: - Added reference to RFC 6811 - Clarification for Legacy Internet Resource Holders You can find the full proposal at: https://www.ripe.net/participate/policies/proposals/2018-06 As per the RIPE Policy Development Process (PDP), the purpose of this four-week Discussion Phase is to discuss the proposal and provide feedback to the proposers. At the end of the Discussion Phase, the proposers, with the agreement of the Working Group Chairs, decides how to proceed with the proposal. We encourage you to review this proposal and send your comments to <routing-wg(a)ripe.net> before 20 June 2019. Kind regards, Marco Schmidt Policy Officer RIPE NCC

2018-06 Can we have additional methods for validation or have the NCC not be so obstinate on doing removals
by Delacruz, Anthony B 29 May '19

29 May '19

I'm very appreciative for the efforts here to clean out the IRR. I am a major resource holder with IP's and ASN's from all the RIR and we also run an IRR. I am often frustrated that when I open a ticket with the NCC and even place an entry in whois on space I own that is clearly listed wrong in RIPE-NONAUTH IRR that it is a multi week struggle to get entries removed and they have me chase the contact that put in the entry which is often not responsive. Since not all of my space right now is easily taken care of using RPKI for this, I would very much like to suggest additional methods be available for the NCC to consider a valid request for removal. Other IRR's I work with we usually send the request from the MNT or POC that is on the account/orgid/lir listed with the RIR and in some cases I go as far as to set whois on the blocks with various messages like "please clear, IRR BAD, Hijacked, Recovered Space" and several other messages to make it understood the range has some reason we don't want an IRR entry to be showing for it. Many of the dozen other IRR are quick and a pleasure to work with but the NCC is not ever easy or prompt on the cases I have put in.

Fw: [db-wg] Suggestion further validity-checking
by ripedenis＠yahoo.co.uk 28 May '19

Colleagues We have had a suggestion (with some support) on the DB-WG mailing list about deprecating the "holes:" attribute in ROUTE(6) objects. Perhaps the Routing WG could consider if this attribute has any value in the RIPE Database. cheersdenis co-chair DB-WG ----- Forwarded message ----- From: Nick Hilliard via db-wg <db-wg(a)ripe.net>To: Edward Shryane <eshryane(a)ripe.net>Cc: "db-wg(a)ripe.net" <db-wg(a)ripe.net>Sent: Tuesday, 28 May 2019, 13:30:30 CESTSubject: Re: [db-wg] Suggestion further validity-checking Edward Shryane via db-wg wrote on 28/05/2019 12:12: > Unfortunately, no cleanup was done when this rule was implemented, > but in recent times we try to do this.

It's used for 643 out of 302354 route: objects and 40 out of 28803 route6: objects, i.e. ~0.2% and 0.1% respectively.

RPKI Route Origin Validation - Africa
by Mark Tinka 21 May '19

21 May '19

Thanks, Job. So we hit the below issue in the first week: https://lists.uknof.org.uk/cgi-bin/mailman/private/uknof/2019-April/006470.… Also in the first week, 2 customers reported an issue accessing some IP addresses in Europe and the U.S. These turned out to be broken ROA's which took a while to fix. Finding the right person in the remote networks (one being a cloud provider) was a bit of a mission. But eventually, it got fixed. Recently, AMS-IX sent out 2 notifications for Invalid ROA's of some of our customers. It was also an incorrect ROA setup, which was fixed in 2 days, each. We are now rolling out ROV to our downstream BGP customers. I don't expect any issues as: - Most of our customers will have a NotFound state. - We will manually check each customer's setup before we turn on ROV for them. We should be done within 3 months or so.

RPKI Route Origin Validation - Africa
by Ben Maddison 21 May '19

21 May '19

Hello all. In November 2018 during the ZAPF (South African Peering Forum) meeting in Cape Town, 3 major African ISP's announced that they would enable RPKI-based ROV (Route Origin Validation), including dropping Invalid routes as part of efforts to improve Internet routing security, on the 1st April, 2019. On the 1st of April, Workonline Communications (AS37271) enabled ROV and began dropping Invalid routes. This applies to all eBGP sessions, both IPv4 and IPv6. On the 5th of April, SEACOM (AS37100) enabled ROV and began dropping Invalid routes. This applies to eBGP sessions with public peers, private peers and transit providers, both for IPv4 and IPv6. eBGP sessions toward downstream customers will follow in 3 months time. Implementation at the third ISP has yet to be completed. We are sure they will communicate with the community when they are ready to do so. Please note that for the legal reasons previously discussed in various fora, neither Workonline nor SEACOM are utilising the ARIN TAL. As a result, any routes covered only by a ROA issued under the ARIN TAL will fall back to a status of Not Found. Unfortunately, this means that ARIN members will not see any improved routing security for their prefixes on our networks until this is resolved. We will each re-evaluate this decision if and when ARIN's policy changes. We are hopeful that this will happen sooner rather than later. If you interconnect with either of us and believe that you are experiencing any routing issues potentially related to this new policy, please feel free to reach out to either: - noc(a)workonline.africa - peering(a)seacom.mu Workonline Communications and SEACOM hope that this move encourages the rest of the ISP community around the world to ramp up their deployment of RPKI ROV and begin dropping Invalid routes. We appreciate the work that AT&T and others have carried out in the same vein. In the mean time, we are happy to answer any questions you may have about our deployments. Thanks, Mark Tinka (SEACOM) & Ben Maddison (Workonline Communications).
