1. A method comprising:
receiving, by a network device, an indication of a failure of one or more network layer links;
determining, by the network device and based on the indication, and based on data indicating one or more associations between network layer links and physical layer links, a physical layer link associated with the one or more network layer links; and
determining, by the network device and based on a total quantity of the network layer links associated with the physical layer link, and based on a quantity of the one or more network layer links associated with the indication of the failure, a score indicating a probability that the physical layer link comprises a failure associated with a break in a physical communication link of the physical layer link.
