Hi,
My experience tells me the looped usually indicates that there is a loop somewhere.
This can be a soft set loopback in either router. A loopback set at either end on the
network termination equipment. The one that gets tricky is if a telco tester has left
a loopback in place mid stream.
Check each end to ensure that the loopback is not configured on the interface. Check
you actually see the loopback from each end. I have had one end in loopback the other
not. This service went to the wrong place mid stream. (the jumpers in an exchange).
Just some thoughts
