Has anyone see a situation where on one side of a lease line connection I see the connection as down down but if I go out of band to connect to the other end I see the serial interface as up up. I would think it is due to a loop but I don't see it say looped on the interface. I tried to reset the interface a few times and rebooted the router 3 times but I still see one end is up and the other down. Is there a loop in the circuit somewhere? If so how up on the side that I see UP UP I don't see an indication of a loop?
I have this problem too.
