ABSTRACT:
A data communications system may include a network having a plurality of network provider routers configured to support Open Shortest Path First (OSPF) circuits between customer edge routers outside the network, an automated diagnostic system coupled to the network provider routers. The automated diagnostic system may be configured to automatically initiate one or more inquiries of one or more of the network provider routers in response to a customer IP address identifying a customer edge router servicing a customer location from which a service failure has been reported and a circuit address identifying an Open Shortest Path First (OSPF) circuit related to the reported service failure. In addition, the automated diagnostic system may be configured to automatically process results of the one or more inquiries to automatically identify whether an Open Shortest Path First (OSPF) protocol problem is present in the network, and to automatically generate a notification for a work center when an Open Shortest Path First (OSPF) problem is identified in the network. Related computer program products and methods are also discussed.
