Hi Rich,

You only have a recursion risk when you have a dynamic routing
protocol advertising the other end of the tunnel and as such, you get
into a situation when the tunnel is advertised via the physical and
the physical is advertised via the tunnel as well, and it gets all
complicated.

But in this situation, the ends of the tunnel are almost directly
connected. I said almost because there is a FR switch between. But
from the IP layer's perspective, they are.
