Agenda for WG at RIPE 72
by Rob Evans 13 May '16

13 May '16

Hi all, This is the agenda for our meeting on the Thursday morning of the RIPE meeting. The astute will notice that despite what I claimed in a previous message, we haven’t managed to secure an additional session for a joint discussion between the Database and Routing Working Groups on authentication of non-authoritative objects. Jared Mauch will be sharing some thoughts on the matter, and I’d remind everybody of Denis’s proposal[1] and subsequent discussion. Others are, of course, welcome to weigh in on the topic. Cheers, Rob [1] https://www.ripe.net/ripe/mail/archives/routing-wg/2015-November/003100.html Routing Working Group RIPE 72, Copenhagen. 09:00 CEST, 26th May 2016. Side Room. A. Welcome 00:05 Thanks to the scribe, jabber scribe and stenographer. Reminder of microphone etiquette. Minutes from RIPE 71. B. Appointment of new co-chair. 00:05 C. 64-bit Extended BGP Communities 00:20 Ignas Bagdonas D. ENGRIT: Extensible Next Generation Routing Information Toolset 00:20 Stavros Konstantaras, NLnet Labs. E.

Hi all, I hope you've got your tickets booked to join us in Copenhagen three weeks from now! We still have some time on the agenda for the routing working group, so if you have some topics to discuss, please drop Joao and myself a message via <routing-wg-chairs(a)ripe.net>. Another reminder that we will also be looking for a new co-chair for the WG. One candidate has already stepped forward, again let us know if you're interested. Cheers, Rob
