new open source tool: prefix list aggregator
by Alexander Zubkov 30 Nov '21

30 Nov '21

Hi, I made tools to aggregate prefix lists, repo is here: https://gitlab.com/qratorlabs/plag There are two tools: plageq - makes strictly equal aggregation of prefixes plagmax - maximally aggregates, discarding subsets They should be already quite useful, so everybody is welcome to use them and leave feedback. I have only found some alternatives available: 1) https://github.com/job/aggregate6 This is almost the same, but it is very slow for big lists and eats zillion bytes of memory. My tools need only a couple of seconds for lists of ~2M prefixes and around ~100M of memory (including spare memory, which is not used, total amount is fixed at compile time now) 2) bgpq4 can also do aggregation while fetching the prefix list. It does it fast too, but it is not perfect. My tool on the other hand generates perfect minimization in case of plagmax. And I suppose minimal possible number of lines in case of plageq (actually it is depth-limited in config now, but for deeper depthes there should be extreme number of prefixes in the list) Here are some examples, comparing it to bgpq4. bgpq4 spends most of the time requesting prefix lists and waiting for a response, so do not pay much attention to its times. # time bgpq4 -4 -F '%n/%l\n' AS2914:AS-GLOBAL >ntt4.0 real 0m 30.38s user 0m 4.29s sys 0m 0.32s # time bgpq4 -4 -A -F '%n/%l{%a,%A}\n' AS2914:AS-GLOBAL >ntt4.eb real 0m 30.41s user 0m 3.98s sys 0m 0.24s # time bgpq4 -4 -A -R 32 -r 1 -F '%n/%l\n' AS2914:AS-GLOBAL >ntt4.mb real 0m 31.71s user 0m 3.94s sys 0m 0.22s # time ./plag/plageq <ntt4.0 >ntt4.ep max nodes: 29.03%, 3044261 / 10485760, 34.84MB / 120.00MB real 0m 0.97s user 0m 0.94s sys 0m 0.03s # time ./plag/plagmax <ntt4.0 >ntt4.mp max nodes: 2.83%, 296843 / 10485760, 2.26MB / 80.00MB real 0m 0.47s user 0m 0.44s sys 0m 0.02s # time bgpq4 -6 -F '%n/%l\n' AS2914:AS-GLOBAL-v6 >ntt6.0 real 0m 7.25s user 0m 1.44s sys 0m 0.03s # time bgpq4 -6 -A -F '%n/%l{%a,%A}\n' AS2914:AS-GLOBAL-v6 >ntt6.eb real 0m 7.14s user 0m 1.22s sys 0m 0.06s # time bgpq4 -6 -A -R 128 -r 1 -F '%n/%l\n' AS2914:AS-GLOBAL-v6 >ntt6.mb real 0m 8.04s user 0m 1.26s sys 0m 0.04s # time ./plag/plageq <ntt6.0 >ntt6.ep max nodes: 11.38%, 1192943 / 10485760, 13.65MB / 120.00MB real 0m 0.40s user 0m 0.37s sys 0m 0.02s # time ./plag/plagmax <ntt6.0 >ntt6.mp max nodes: 2.57%, 269912 / 10485760, 2.06MB / 80.00MB real 0m 0.22s user 0m 0.19s sys 0m 0.03s # cat ntt4.0 ntt6.0 | shuf | time ./plag/plageq >ntt.ep max nodes: 40.41%, 4237202 / 10485760, 48.49MB / 120.00MB real 0m 2.44s user 0m 2.20s sys 0m 0.07s # cat ntt4.0 ntt6.0 | shuf | time ./plag/plagmax >ntt.mp max nodes: 10.16%, 1065244 / 10485760, 8.13MB / 80.00MB real 0m 1.33s user 0m 1.04s sys 0m 0.04s And here are number of lines in the resulted files: 2038959 ntt4.0 <- unaggregated ipv4 prefixes 414558 ntt4.eb <- bgpq4 equal set 395831 ntt4.ep <- plag equal set 128522 ntt4.mb <- bgpq4 minimal 99794 ntt4.mp <- plag minimal 540047 ntt6.0 <- unaggregated ipv6 prefixes 80764 ntt6.eb <- bgpq4 equal set 79875 ntt6.ep <- plag equal set 38193 ntt6.mb <- bgpq4 minimal 38023 ntt6.mp <- plag minimal

Open Source WG & Virtual Meetings
by Martin Winter 18 Dec '20

18 Dec '20

As mentioned at the end of today's Open Source WG Session, I would like to discuss and get some thoughts from the community on this topic. Recap for the ones which missed the session: The last 2 RIPE meetings were virtual without the usual hallway talks. Our current charter states: "The aim of the Open Source Working Group is to foster discussion among developers, Internet Service Providers and the rest of the RIPE community about open source projects related to the RIPE community" With virtual meetings, the "discussion" outside of the short WG session is much more difficult. RIPE is doing a good job trying to keep the RIPE as a "meeting" and not turning it into a "conference", but the lack of the physical meeting changes many things. Probably much easier to attend, but then some Open Source contributors prefer to meet with the community and get a 2-way exchange. I don't necessarily think we need to change anything, but I would like to have this discussion here on the list to see if there are ways to improve on how we function as a WG. If you have any good ideas, then go ahead and mention them here. Please keep in mind that this is not a discussion of virtual vs physical meetings. That decision is up to RIPE, not the WG. This is just on how we, as a WG, could potentially work better on virtual meetings. Let's discuss. Any cool ideas? Martin Winter Open Source WG Co-Chair

NetBox
by Sander Steffann 16 Dec '20

16 Dec '20

Hi everybody, I have the feeling a lot of people are using NetBox, and I wonder how you are all dealing with things that are not supported or not working the way you want/need. My personal biggest requirement has been to be able to trace DWDM connections accross circuits and patch panels. I became a NetBox maintainer for a while and worked on getting this implemented right in NetBox 2.8 and 2.9. But now 2.10 has been released, and no path trace will traverse a circuit anymore. I have no idea why it's been broken again, and to be honest I don't have the energy to go back and fix it *again*. Jeremy (NetBox "manager") just told me to file a feature request to restore the broken functionality, which is not very helpful. I was wondering: how do other NetBox users deal with this? Maintain your own fork (there seem to be MANY forks on GitHub), stick with a version that works, ...? I know there are people already looking to do a LibreNMS-style fork of NetBox and continue development under more community-friendly management. Would people be interested in something like that? Because that's definitely the style that I want to contribute to :) Cheers, Sander
