I would like to hear what others are doing for BCP38 deployments for
BGP customers. Are you taking the stance of "if you don't send us
the prefix, then we don't accept the traffic"? Are you putting in
some kind of fall back filter in based on something like IRR data?

In the case of Juniper, you can use the same prefix-list in your BGP
policy (you are applying a filter to your customers' BGP announcements,
right?) and the uRPF exception list.
