The two router vendors that are vocally represented here don't seem to
support that view, however. How do you define "unsustainable"? You can
create non-convergence today in the lab by simply causing a set of BGP
speakers generate flap faster than the unit under test. You can also
create that in the field today by putting woefully underpowered CPU
(anyone still got a CSC-4 handy? ;-) in the core. What we see today is
that convergence is slowing, but it's difficult to argue about when (or
if) it will get to non-convergence, given Moore's law and technology
refresh cycles.
