Doug Madory@eldomador.bsky.social · last yr.In this post for @kentik.bsky.social, @jobsnijders.bsky.social and I dig into the problem of excessively large AS-SETs — out of control route objects which can render IRR-based route filtering useless. Includes data analysis from @benjojo.bsky.social founder of bgp.tools.
I wonder how many 6500s/7600s are still out there, which have a theoretical limit of 1024k prefixes in TCAM, and are about to explode? :D
bot.bgpstuff.net@bot.bgpstuff.net · last yr.I see 998964 IPv4 prefixes. This is 132 more prefixes than 6 hours ago and 860 more than a week ago. 61.76% of prefixes are /24.
I'm now reading this, a must read for making use of one of Rust's most powerful features, thank you @mara.bsky.social !
Badr@pythops.com · last yr.One of the best books I have ever read ! A true goldmine. Thanks a lot @mara.bsky.social marabos.nl/atomics/
