> Further in your specific case of a ping check... that is near worthless to a lo0 route as it can't tell when the carrier has dropped on an interface

No, no, I was thinking about incoming ICMP echo replies delivery. Some external
resource is checked by its IP address, of course. Not even remote IP of PPP
interface if we need to check global connectivity - we ping some global
resource with source IP of distinct link.
