The morning was focused primarily on BGP:
- Lefteris Manassakis described how CodeBGP tools can detect route leaks, including an interesting story of an Indian ISP originating a prefix for a root DNS server under its own AS.
- Ben Cartwright-Cox introduced bgp.tools, including the weirdest use of 1GE transceivers I’ve ever seen.
- Riccardo Stagni had a brief update on RIPE RPKI tools. It was really nice to see they already have some rudimentary support for ASPA.
- Nicola Modena continued his journey into underappreciated BGP features, this time talking about service insertion using BGP FlowSpec.
No event would be complete without a presentation or two about out-of-this-world hyperscaler technologies. This time, Massimo Magnani introduced gRIBI (real-world I2RS twin using gRPC as the transport protocol), and Colin Whittaker talked about custom AWS switches1.
Last but definitely not least, my friend Roman Dodin had a lovely containerlab presentation, giving me a few ideas how to do a better job introducing netlab 😉, and Paolo Lucente & Salvatore Cuzzilla introduced yet-another next-generation streaming telemetry solution that made my head spin.
Finally, ITNOG stands for Italian Network Operators Group, so unsurprisingly the presentations of Italian speakers were in Italian. I probably managed to get the gist of most of them from the slides, but then there were some presentations like the accelerated virtual networking presentation by Samuele Pilleri where based on the diagrams I would assume it wasn’t bad, but even the slides were in Italian, so whatever.
Is it worth attending ITNOG? Absolutely if you’re speaking Italian. Probably even if you’re not fluent in Italian2. Will I be back? You bet.
