From the traces I've seen, it seems if the first Sprint hop is sl-bb20-dc, the private IP hops don't show up. If the first Sprint hop is sl-crs2-dc, then the private IP hops are there. I wonder if anyone from Sprint can shed some light on that?

That's an interesting correlation, but maybe they don't appear because a router
in the path is dropping packets sourced from private IPs?
