AS6302 a multihomed sprint/mci customer is announcing
204.70.195/24 (a MCI backbone network) to sprintlink, and
spintlink is accepting it and announcing it to the world.
Is sprintlink not filtering announcments they get from customers?
Sprintlink has only ever claimed to implement inbound filtering.
Sean was hoping that other providers would filter inbound as well,
but that didn't happen for quite a while...
