Maybe some publicly documented case studies would be nice? Or is that
all just too "topic secret" to tell your competitors how to do?

That said, my second-to-last employer wouldn't actually handle BGP communities
that they documented they'd accept.. with that kind of consistency are you
surprised that the slightly-less-than-"nanog"-cluey-netadmins crowd of
network administrators don't bother with BGP juju and stick to what works?


(And no, they still don't accept the communities they document they would; nor
tag traffic with DSCP bits they documented they would. Fun times.)
