I haven't tried doing that with igp protocols.. But with BGP, it works does
manage to bind itself to the working address. (Or if you are sourcing update
to loopback, that would be fine too)

The thing is... some people want to hide the IP of the interface that faces
their transit on the border router, as most /30 demarcation subnet is assigned
from the transit. And since they would run either bgp or static route between
the transit and their border router, it shouldn't break routing..
