Again, as it was stated, the size of or number of BGP communities wasn't the problem anyway; it was hashing / memory storage. And you know what? Hashing / memory storage HAS been a problem with multiple vendors in many other contexts, not just BGP community stuff. Has nothing to do with "2023 hardware". You can bog down top of the line DDR5 memory pretty easily if you make certain coding choices.
I suppose that can be said of anything in our industry. There is always a way we can hurt ourselves, especially if we ignore or have not learned our lessons.
With the information that I have, I don't consider it a massive issue at the moment. Of course, that is always a changing landscape, and my views may alter when that happens sufficiently. But as of now, I am dealing with far more severe BGP bugs than what appears to have been, at least for the moment, fixed.
You can choose ( as you apparently have ) to just presume that a problem that happened before won't ever happen again. Prob not a great idea though.
Ummh, okay... Mark.
