Path validation with RPKI
by Iljitsch van Beijnum 20 Jun '19

20 Jun '19

Dear secure interdomain routing operators, I've been away from the IETF for a while, and I'm new to this mailing list, so I'm not up to date with what's been happening here. I'm not going to let that stop me :-) but apologies if I retread worn out paths. Also, I'm not sure if this work ultimately fits this wg, but I think this is the right place for an initial discussion. I'm also starting this discussion on the RIPE routing-wg list. A few weeks ago there was a significant route leak through Safe Host and China Telecom. This keeps happening. I think we can stop these route leaks with a relatively modest change to RPKI: by combining the ASes the origin trusts and the ASes the operator of an RPKI relying party server trusts, we have a list of all the ASes that may legitimately appear in the AS path as seen from this particular vantage point. I believe deployment will be relatively easy, as it works for the two ASes at both ends even if ASes in the middle don't participate. So this means a change to the ROA format, a change to the RPKI-router protocol, and of course changes to the software involved. Here is the draft: https://datatracker.ietf.org/doc/draft-van-beijnum-sidrops-pathrpki/ <https://datatracker.ietf.org/doc/draft-van-beijnum-sidrops-pathrpki/> There is path filter example code in the appendix to show that this part is easy. :-) In case you want to try this out but don't want to compile it yourself, (mostly) the same code is also running here: http://bgpexpert.com/pathrpki/ <http://bgpexpert.com/pathrpki/> Probably not too much new information for this group, but some background: http://www.muada.com/2019/06-13-lets-fix-those-bgp-route-leaks.html <http://www.muada.com/2019/06-13-lets-fix-those-bgp-route-leaks.html> Note that this is significantly different from the AS-Cones proposal. AS-Cones is a way for transit ASes to filter their peers (and maybe their customers). RPKI path validation is everyone filtering all prefixes they see, regardless of whether these prefixes come in through peering or transit. However, there is no reason the two can't be deployed side by side. I've also read the ASPA draft, and although there are some overlap between ASPA and RPKI path validation, I'm not entirely clear on the details but they seem to be very different. Iljitsch

Path validation with RPKI
by Iljitsch van Beijnum 20 Jun '19

20 Jun '19

Dear routing-wg'ers, A few weeks ago there was a significant route leak through Safe Host and China Telecom. This keeps happening. I think we can stop these route leaks with a relatively modest change to RPKI: by combining the ASes the origin trusts and the ASes the operator of an RPKI relying party server trusts, we have a list of all the ASes that may legitimately appear in the AS path as seen from this particular vantage point. I believe deployment will be relatively easy, as it works for the two ASes at both ends even if ASes in the middle don't participate. So this means a change to the ROA format, a change to the RPKI-router protocol, and of course changes to the software involved. I'm interested to hear what everyone thinks of this, and especially what the developers of implementations think. Here is the draft with the protocol modifications: https://datatracker.ietf.org/doc/draft-van-beijnum-sidrops-pathrpki/ <https://datatracker.ietf.org/doc/draft-van-beijnum-sidrops-pathrpki/> There is path filter example code in the appendix to show that this part is easy. :-) In case you want to try this out but don't want to compile it yourself, (mostly) the same code is also running here: http://bgpexpert.com/pathrpki/ <http://bgpexpert.com/pathrpki/> And if you need more background: http://www.muada.com/2019/06-13-lets-fix-those-bgp-route-leaks.html <http://www.muada.com/2019/06-13-lets-fix-those-bgp-route-leaks.html> Note that this is significantly different from the AS-Cones proposal.

However, there is no reason the two can't be deployed side by side. Iljitsch

This is an automated weekly mailing describing the state of the Internet Routing Table as seen from APNIC's router in Japan. The posting is sent to APOPS, NANOG, AfNOG, SANOG, PacNOG, SAFNOG TZNOG, MENOG, BJNOG, SDNOG, CMNOG, LACNOG and the RIPE Routing WG. Daily listings are sent to bgp-stats(a)lists.apnic.net For historical data, please see http://thyme.rand.apnic.net. If you have any comments please contact Philip Smith <pfsinoz(a)gmail.com>.

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.
