Sprint Flapping?

According to Sprint NOC at 800-669-8303 they are experiencing routing
instabilities due to a "Cisco Feature". Not sure what that means. Earlier,
it stated a Cisco Seattle router failure. I haven't seen an advisory come
by way of email from the Sprint ISC. We are seeing a huge amount of
routes dampened at mae-east and mae-west.


Hmmm, this occurred pretty soon after Sprint eliminated their 'visible
confederations' hack.

Maybe they triggered a bug in the route reflector code?
