Hi all, In the attachment is raw data that was used in https://ripe77.ripe.net/presentations/123-RIPE-NONAUTH.azimov.pdf It shows a list of globally visible prefixes that have route objects ONLY in RIPE-NONAUTH. For these prefixes, the removal of route objects from this database may lead to DoS. *Numbers for IPv4:* Total number of objects - 69178 Address space covered In other IRRs - 43527 Address space covered In other IRRs with same ASN - 33839 Unique Objects in RIPE-NONAUTH - 25651 Globally visible prefixes – 4507 ASNs - 543 *Numbers for IPv6:* Total number of objects - 1991 Address space covered In other IRRs - 1502 Address space covered In other IRRs with same ASN - 1336 Unique Objects - 489 Globally visible prefixes – 303 ASNs - 86 I haven't yet analyzed to which IRRs the route objects from NONAUTH should belong.

Hi, I support the proposal and I'd like to add a **quick'n dirty** "impact analysis". 1) I took the 69178 [1] RIPE-NONAUTH route objects and run them through RPKI validator* 3. Which gives me 758 RPKI INVALID (669 ASN mismatch + 89 ML mismatch) objects. These objects would be the once that get removed as per the proposal. distribution by RPKI validity state: 67904 UNKNOWN 669 INVALID_ASN 516 VALID 89 INVALID_LENGTH 2) to estimate the impact of the route object deletion I then further categorize these 758 prefixes by asking: - Are they currently announced? (visible in RIS) - Are they currently announced by the origin in the route object? I only looked at exact matches - not less specifics. (RIPEstat prefix-routing-consistency data call was used to answer these questions) If one of these two questions is answered with "no", then I expect the potential impact of the deletion to be smaller than the other once (where both questions are answered with "yes"). Only 55 [3] objects (28 unique ASNs) are currently announced and match the origin in the route object.

source: RIPE may also contain invalid ROUTEs
by denis walker 18 Oct '18

18 Oct '18

Hi guys There is a corner case where invalid ROUTE(6) objects may occur in the source: RIPE database. Before NWI-5 a ROUTE(6) object could be created either by the address space holder or the ASN holder. Both had to authorise the creation, but whoever created the object would maintain it. Suppose the ASN holder created an object and maintains it, then the address space holder chooses another ASN to announce the address space. The address space holder can delete the ROUTE(6) object using the Force Delete mechanism(1), if they know about it. But many resource holders still don't know such mechanisms exist. They may instead just create an RPKI ROA for the new announcement and leave the old ROUTE(6) object in the database. AFAIK there isn't yet any alignment mechanism, but it has been talked about recently, and the cleanup proposal under discussion only applies to source: RIPE-NONAUTH (but I'm not suggesting you extend it). Although this is a corner case, it means you can't guarantee all the data in source: RIPE is still authoritative.

New on RIPE Labs: The RPKI Observatory
by Mirjam Kuehne 17 Oct '18

17 Oct '18

Dear colleagues, In this RIPE Labs article nusenu talks about why it is important to take care of RPKI misconfigurations, what the impact of ignoring them is, how network operators can easily determine whether they are affected by a specific RPKI misconfiguration and how significantly the amount of RPKI unreachable IP space changed over the course of just a few weeks. https://labs.ripe.net/Members/nusenu_nusenu/the-rpki-observatory Kind regards, Mirjam Kühne RIPE NCC

Fw: [db-wg] RIPE Policy Proposal 2018-06 Aims to Delete Conflicting Non-authorative IRR Objects

First is a technical issue with your proposal. In your Rationale you mention ¨creating out of region inetnums¨. It wasn't possible to create such objects. Only out of region aut-nums and route(6)s. You talk about cleaning up garbage in the RIPE-NONAUTH IRR. The principle of cleaning up garbage is always good. But doesn't this still leave a lot of potential garbage in all the commercial IRRs where ROUTE objects can still be created without authorisation by, consent from and knowledge of the address space holder? So should we also be promoting the RIRs authoritative IRRs over commercial IRRs so that ROUTE objects can all be created with proper authorisation? cheersdenisco-chair DB-WG From: Job Snijders via db-wg <db-wg(a)ripe.net> To: Nick Hilliard <nick(a)foobar.org> Cc: Marco Schmidt <mschmidt(a)ripe.net>; db-wg(a)ripe.net Sent: Sunday, 14 October 2018, 8:49 Subject: Re: [db-wg] RIPE Policy Proposal 2018-06 Aims to Delete Conflicting Non-authorative IRR Objects Dear Nick, On Sat, Oct 13, 2018 at 10:38:12PM +0100, Nick Hilliard via db-wg wrote: > Marco Schmidt via db-wg wrote on 11/10/2018 14:18: > > We just published the RIPE Policy proposal, 2018-06, "RIPE NCC IRR > > Database Non-Authoritative Route Object Clean-up", to the Routing > > Working Group mailing list. > > > > The goal of the proposal is to delete an non-authoritative object > > stored in the RIPE IRR, if it conflicts with an RPKI ROA. > > There are some corner cases where this could cause permanent and > unwarranted pain. > > 1. what's the procedure for backing out the deletion if the ROA holder > in the other RIR makes a mistake and, for example, forgets to create a > roa for a specific ASN and then they find their RIPE-NONAUTH route > object deleted by accident. When an operator makes a mistake, they've made a mistake. The same already applies today when the operator changes the ASN in the route/route6 object to the wrong origin ASN. The proposal does not have a 'back out' procedure; once a route/route6 object in RIPE-NONAUTH becomes in conflict with a RPKI ROA it should no longer exist. A different way of looking at things: What the policy proposal in a nutshell does is apply the RFC 6811 BGP origin validation process to IRR data. You could view the IRR data as if they are BGP announcements in context of 6811. Example: An IRR route object in RIPE-NONAUTH states that for prefix 206.48.168.0/22 a possible origin is AS4663 - but a set of PKI ROAs exists: 206.48.0.0/16 AS5511 maxlength 24 206.48.0.0/16 AS6505 maxlength 24 206.48.0.0/16 AS51964 maxlength 24 Obviously "206.48.168.0/22 AS4663" conflicts with the above set of ROAs and would be marked with origin validation state 'invalid'. This means that any network applying RPKI based BGP Origin Validation will reject the BGP announcement "206.48.168.0/22 AS4663", even though someone documented in the RIPE-NONAUTH IRR that that announcement perhaps could exist. The RIPE-NONAUTH IRR route object describes a state of the network that is to be discarded anyway - so deletion is warranted as it closes holes in prefix-list based filters in networks not doing OV. Also note that in the above scenario the owner of the ARIN-managed 206.48.0.0/16 prefix never was consulted or consented to the creation of the 206.48.168.0/22 route-object in the RIPE IRR. Leaving such objects laying around is a disservice to the global community - when there is clear and unambigious data that shows the IRR route object describes a route announcement that is to be rejected anyway. > 2. what happens when someone is busy creating ROAs in, for example, > Magastan and the RIPE NCC runs a deletion process mid-way through that > process When someone needs to create multiple ROAs, but only publishes one - it is an operator error. When one misconfigures things... they are misconfigured, no big deal. This is why for example the RIPE RPKI portal allows you to queue up RPKI ROA modifications and publish the batch in one go. By the way, What is "magastan" and what does it have to do with the topic at hand? To me "quality data" means that the routing information was created with the explicit consent of the owner of the resource - this is something the RPKI offers us. If the owner chooses to publish incorrect routing information (for example: wrong origin ASN) that is entirely up to them. > 3. the above situations are complicated by RFC6382. Why? Section 6 of RFC 6382 explicitly states: "Additionally, this technique sets the stage to employ RPKI-enabled machinery and more secure and explicit routing policies, which all network operators should be considering." What is your concern, how does RFC 6832 change anything? Perhaps you can provide us with a tangible example scenario? > It might be a good idea to send some warnings to the holders of the > route/route6 objects before nuking their objects + build in a timeout > period. "their objects"?! We can not assume that the owner of a resource ever asked for the objects in the first place. There are objects in the RIPE-NONAUTH IRR that cover NTT Communications' resources where we've never consented to their creation - since we are not the maintainer and perhaps dont even have any relation with the creator of such objects, we have no recourse to delete such objects. When we create RPKI ROAs covering such route objects it is a clear public statement about which ASNs are authorised to originate those prefixes. Any IRR information that is in conflict with such information should be considered rogue and a risk to our business. It'll take time before we see a great many networks deploy BGP Origin Validation based on RPKI data, so an incremental beneficial step forward is to apply the same origin validation procedure to unvalidated IRR data, this closes loopholes. To me keaving the rogue IRR objects in place and telling the industry to just deploy Origin Validation to mitigate the effects of RIPE-NONAUTH objects would be unreasonable. RIPE-NONAUTH is a pile of garbage, we need to offer folks an easy way to delete the portions of it affecting their resources (knownig that these resource owners probably never have been aware those route/route6 objects existed in the first place!). Kind regards, Job

2018-06 New Policy Proposal (RIPE NCC IRR Database Non-Authoritative Route Object Clean-up)
by Marco Schmidt 16 Oct '18

16 Oct '18

Dear colleagues, A new 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. 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 9 November 2018. Kind regards, Marco Schmidt Policy Officer RIPE NCC Sent via RIPE Forum -- https://www.ripe.net/participate/mail/forum
