i have yet to see any service provider use BGP confederation in production.
The idea seems kinda neat, but Route reflectors scale so well nowadays, that a confederation setup seems kind of wasteful and overly complex. Especially with behaviour like this appearing.
Also, im curious how other routing operating systems would behave when encountering massive AS-paths.
According to the article, IOS seems to crash irregulary. I wonder if these kind of things are being fuzzed by the network operating system vendors aswell, especially conisdering there is no upper limit on AS-PATH length defined in the RFC.
