For repeat offenders create a list of networks that won't
implement BCP 38 and collectively de-peer with them telling
them why you are de-peering and what is required to
re-establish connectivity. It is in everyones interests
to do the right thing here.
people inside one of the largest networks have told me that they have
customers who require the ability to bypass BCP38 restrictions, and that
they will therefore never be fully BCP38 compliant. i've asked for BCP38
to become the default on all their other present and future customers but
then there was whining about bankruptcy, old outdated equipment, and so on.
sadly, there's no way to de-peer this network, or any other multinational,
and so there will be no "peer pressure" on them to implement BCP38.
