i would argue all of them; they are so tied to each other that its hard
for me to distinguish. bgp does not let you do everything you want, and at
times lets you do things you don't want. moreover, to my knowledge, the
way most people configure it is also primitive.

but our immediate goal is more modest - trying to understand whats going
on and what the impact of it is. the more challenging task of fixing
things will come later, when we know the current world better.
