Root-cause problems

Root-cause problems diagnosed by Network Protocol Manager for OSPF lists the root-cause problems that are diagnosed by Network Protocol Manager for OSPF. For each problem, Table 6 identifies the managed object for which the problem is diagnosed, the condition for the problem, and the events that are correlated by Network Protocol Manager for OSPF to diagnose the problem.
