aggregate6 - a fast versatile prefix list compressor
by Job Snijders 30 Nov '17

30 Nov '17

Dear routing-wg, I re-implemented the venerable 'aggregate' tool (by Joe Abley & co) in python under the name of 'aggregate6'. The 'aggregate6' tool is faster and also has IPv6 support. https://github.com/job/aggregate6 Installation is can be done through 'pip', or your operating system's package manager (if they carry the 'aggregate6' tool). $ pip install aggregate6 Example use: $ echo 10.0.0.0/16 10.0.0.0/24 2000::/4 3000::/4 | aggregate6 10.0.0.0/16 2000::/3 Note that 'aggregate6' can also be imported as module in your own python project: >>> import from aggregate6 import aggregate >>> aggregate(["10.0.0.0/8", "10.0.0.0/24"]) ['10.0.0.0/8'] >>> Related to the above example, NTT uses 'aggregate6' as library in their network automation toolchain to help compress firewall rules. When using a dump from the IPv4 Default-Free Zone, it appears that 'aggregate6' can deaggregate that list ~ 50 times faster than 'aggregate'. However the tradeoff is that 'aggregate6' uses a bit more memory. Aggregate6 has been tested with pypy, python2 and python3; and can be used both from the command line and as python module. Aggregate6 is published under the 2-Clause BSD license. Kind regards, Job

DB WG NWI-5 proposal and new routing WG co-chair
by Paolo Moroni 02 Nov '17

02 Nov '17

Dear colleagues, a couple of news from RIPE-75: you might find useful to know about them before the WG minutes are published. 1) Please find enclosed the NWI-5 proposal of the DB working group, which might be of interest for those who use the RIPE DB as input to build BGP filters. The proposal was discussed in the DB working group mailing list and at the RIPE-75 meeting. The DB WG co-chairs have declared it reached consensus and the implementation is progressing. 2) Joao Damas decided to step down as routing WG co-chair; your new co-chair is Ignas Bagdonas. On behalf of the WG, I wish to thank Joao for his many, many years in support of our activities and I welcome Ignas as new co-chair. As always, you can reach us at <routing-wg-chairs(a)ripe.net>. Regards, Paolo Moroni Routing WG co-chair ---------- Forwarded message ---------- From: db-wg [mailto:db-wg-bounces@ripe.net] On Behalf Of William Sylvester via db-wg Sent: Donnerstag, 19. Oktober 2017 17:41 To: William Sylvester via db-wg <db-wg(a)ripe.net> Subject: [db-wg] NWI-5 Out of region ROUTE(6)/AUT-NUM objects implementation request DB-WG Members, Support was shown for the proposal NWI-5 and no objections were raised after this round of discussion. At this time, the chairs request that the RIPE NCC schedule implementation of NWI-5 as described. This request is to remove origin: and flag route objects as specified. The db-wg therefore ask the RIPE NCC to prepare an impact analysis, followed by an implementation plan and timeline for this request and the other issues raised in the problem solution of NWI-5 as follows: 1) Remove the "origin:" authorization requirement. 2) Flag "route:" objects for non-RIPE-managed space with "source: RIPE-NONAUTH" to identify non-authoritative data. Thank you all for your work on this proposal! Kind regards, William & Denis DB-WG co-chairs
