Good afternoon friends I'm having this problem of OSPF crash, this edge server is 150km away, because it's another city that I serve a client there. But since I did OSPF it just keeps falling down and the client keeps complaining to me that the connection is bad that he can't make a call on whatsapp because it keeps failing. even in my main tower I get the fiber in my link after there I do only 2 PTP of 48km and the other of 50km all are with good signal. What could be causing this drop in OSPF?
Below are the images of how this is
