Routing WG agenda for RIPE 66
by Rob Evans 26 Apr '13

26 Apr '13

All, With apologies for this being issued so late, here is the working agenda for our meeting in Dublin. We are likely to add one more talk to this next week, but I'd also ask you to note item (D). It was suggested that we have a panel discussion on this topic, but I've not had the opportunity to set it up, so instead I would like to you to have a quick think about the pros and cons of not advertising infrastructure/IXP prefixes (e.g. not having to sink a multi-Gbps DDoS reaching your network, vs breaking traceroute and PMTU discovery) for a discussion at the microphones, and to see if there is some work we can do as a working group. We may still come back to this as a panel discussion in Athens later in the year. A. Administration i) Microphone etiquette ii) Scribe, Jabber, Stenography iii) Minutes from RIPE 65 iv) Agenda bashing B. Route Object Creation Issues  George Michaelson C. Segment Routing Clarence Filsfils and Christian Martin D. Open discussion on advertising IXP and backbone prefixes E. AOB All the best, Joao and Rob

New on RIPE Labs: The BGP Visibility Scanner
by Mirjam Kuehne 24 Apr '13

24 Apr '13

[apologies for duplicates] Dear colleagues, Please find some interesting research by Andra Lutu, Marcelo Bagnulo and Olaf Maennel on RIPE Labs: "The BGP Visibility Scanner" https://labs.ripe.net/Members/andra_lutu/the-bgp-visibility-scanner The authors developed a tool that checks if prefixes have limited visibility. The article describes some of the results found after analysing many months of global routing table data. Please also note the call for feedback at the end of the article. Kind regards, Mirjam Kuehne RIPE NCC
