Re: [routing-wg] 2019-08 Review Phase (RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space)

Hi Job,
I don't think I'm the one that should calculate that. However, if we have an alternative proposal with the SLURM file, it can be calculated (approximately) as part of the analysis impact that will be needed as well, right?
May be anyone from the community that already has done that job and integrated the SLURM in their routers, can provide an estimate cost, and then multiply it for the number of all the RIRs members?
I believe (I may be wrong) that the AS0 is much cheaper to implement by RIPE NCC even if it is several thousand euros, than the number of worldwide folks that will need to use the SLURM in addition to RPKI (for non-AS0).
Regards,
Jordi

Can you provide us with an estimate of the cost to the collective community if this proposal is *not* implemented as RPKI ROAs but just as SLURM file instead?
Kind regards,
Job

2019-08 Review Phase (RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space)
by Petrit Hasani 03 Mar '20

Dear colleagues,
Policy proposal 2019-08, "RPKI ROAs for Unallocated and Unassigned RIPE NCC Address Space", is now in the Review Phase.
The goal of the proposal is to ask the RIPE NCC to create ROAs with origin AS0 for all unallocated and unassigned address space under its control.
The proposal has been updated following the last round of discussion. Version 2 of the proposal includes a specification for the RIPE NCC to create all AS0 ROAs under a specific Trust Anchor.
The RIPE NCC has prepared an impact analysis on this latest proposal version to support the communityās discussion.
You can find the proposal and impact analysis at:
https://www.ripe.net/participate/policies/proposals/2019-08
https://www.ripe.net/participate/policies/proposals/2019-08#impact-analysis
And the draft documents at:
https://www.ripe.net/participate/policies/proposals/2019-08/draft
As per the RIPE Policy Development Process (PDP), the purpose of this four week Review Phase is to continue discussion of the proposal, taking the impact analysis into consideration, and to review the full draft RIPE Policy Document.
At the end of the Review Phase, the Working Group (WG) Chairs will determine whether the WG has reached rough consensus. It is therefore important to provide your opinion, even if it is simply a restatement of your input from the previous phase.
We encourage you to read the proposal, impact analysis and draft document and send any comments to <routing-wg(a)ripe.net> before 20 March 2020.
Kind regards,

Dear colleagues,
From Saturday 22 February at 08:24 (CET), any newly created, modified, or deleted ROAs (176 in total) could not be added to our publication server due to a disk problem. From that moment on, all the data was stored on the database, but the publication did not happen. The disk did not report any problems and, therefore, no engineer was alerted of this incident.
Due to the disk problem, starting from Sunday 23 February at 09:10 (CET), our CRL expired and our repository could not be properly updated. This was reported to us on Monday 24 February at 11:44 (CET). Immediately, our engineers fixed the disk problem, however, since the CRL expired, all underlying objects also expired. Depending on the Relying Party software an operator used, this abnormal behaviour appeared differently.
Initially, our engineers tried to do a full re-population of the RPKI repository, but unfortunately, this did not update the CRL in the validation tree. At 15:03 (CET), we performed a full CA key-roll, which was completed at 21:02 (CET) and resolved the problem. At 19:58 (CET), all objects in the backlog were published.
We apologise for any inconvenience this may have caused and we are taking all the necessary steps to ensure this incident does not appear again in the future.
Kind regards,
Nathalie Trenaman

Dear colleagues,
As presented at the last Routing WG meeting at RIPE 79, the RIPE NCC is planning on carrying out
an extensive technical and procedural audit on RPKI throughout this year.
We are currently looking for an organisation that can help us with this exercise.
Particularly, we are looking for an organisation that is familiar with the RPKI audit frameworks and ,ideally, has extensive knowledge on BGP routing and cryptography.
We are planning on starting the consultation in two weeks and are looking forward to your recommendations.
Kind regards,
Nathalie Trenaman

An agreed community value to signify test invalid prefixes would help. Maybe a ripe doc (399 or 706) could be updated?
Maybe a discussion point for next meeting.

Hi to everyone,
I would like to inform you that it's been almost one month since
Forthnet started dropping invalid prefixes on all peering/transit links,
either national or international. It's important to note that during
this month we haven't received any complaints.
Having monitored the invalid prefixes for more than a year and
experimenting with routing them across different links, we decided that
it was time to move to the next phase and start dropping prefixes that
are declared as invalid in the RPKI ecosystem.
Two were the main reasons that helped us take the drop decision: a)
during the last year our volume of invalid prefixes traffic decreased
from ~1% of total traffic to less than 0,2%, b) we updated our prefix
validation policy by including a whitelist (until we evaluate SLURM) in
order to bypass issues quickly if/when they arise.
Note #1: in the context of the above actions we have noticed that
invalid prefixes used for testing purposes have recently begun to grow
(each large provider creates one?). This may lead to incorrect
conclusions in the future (at least in terms of prefixes, since i don't
expect traffic from those). Maybe these invalid prefixes should have
some extra "attributes" in order to be recognized more easily while
troubleshooting.
Note #2: In order to increase adoption of a similar policy, maybe MANRS
should be updated to promote dropping invalids. If i'm not mistaken,
their current action is about creating ROAs only.

I wrote a simple tool to figure out what kind of invalid a rpki invalid
is, this can aid people in understanding the impact of "invalid ==
reject" routing policies. Only "invalid_unreachable" routes present
an operational issue in my opinion, IP addresses covered by "notfound"
or "valid" less specific routes will still be reachable.
You pass it a file name (or via stdin) with one prefix and origin ASN
per line (white space separated) representing your full BGP RIB, and
then you can grep specific for the task at hand to extract the info you
need:
$ rpki-ov-checker full_rib | fgrep -f customer_prefixes | grep invalid | sort -R | head
invalid_covered_by_notfound 123.101.0.0/21 4809 covering route: 123.101.0.0/16 4134
invalid_covered_by_valid 46.3.74.0/24 134121 covering route: 46.3.0.0/16 207636
invalid_unreachable 83.231.209.0/24 3949
invalid_unreachable 124.30.247.0/24 9583
invalid_covered_by_valid 125.21.232.0/24 9730 covering route: 125.21.0.0/16 9498
invalid_unreachable 120.29.92.0/24 17639
invalid_unreachable 31.40.164.0/24 200872
invalid_covered_by_notfound 45.12.139.0/24 40676 covering route: 45.12.136.0/22 35913
invalid_covered_by_valid 122.160.178.0/24 24560 covering route: 122.160.0.0/16 24560
invalid_covered_by_valid 61.90.251.0/24 21734 covering route: 61.90.192.0/18 7470
NTT is using this to figure out who we need to help fix their ROA or
correct their BGP announcements.
