We don't accept a default from anyone, but will send one to a customer when specifically requested.
We heavily filter all incoming routes (bogon, 1918, and many others). We don't want data resorting to 0/0 and ::/0 when we specifically rejected the matching route at the import policy. Additionally, if your upstream isn't announcing a route to you, where are they going to send your traffic anyway?
