I'm assuming everyone uses uRPF at all their edges already so that eliminates the need for specific ACEs with ingress/egress network verification checks.

You're new here, aren't you? :)

Hopefully optimistic. Don't bum me out going into a weekend... :-)

From the looks of my ingress BOGON ACLs on my borders (yes, I'm using ACLs and not null routes for a reason) I'd most people not reading NANOG (and maybe even some of them!) are not doing any ingress filtering on their customer source IPs. Sad....
