Abstract
Methods and apparatus to detect and restore flapping circuits in IP aggregation network environments are disclosed herein. An example method for use in maintaining a communication network includes retrieving information related to an operating state of a device associated with a network disturbance; determining whether the information related to the operating state of the device is indicative of a flapping condition; when the operating state information indicates that the flapping condition is present in the network, determining a cause of the flapping condition; when the cause of the flapping condition is a physical cause, selecting a first recovery procedure; and when the cause of the flapping condition is a logical cause, selecting a second recovery procedure different from the first recovery procedure.
