Abstract
A method and apparatus for identifying a Label Distribution Protocol (LDP) flapping event in a communication network are disclosed. For example, the method counts a total number of LDP session up events, a total number of LDP session down events, a total number of link up events, and a total number of link down events within a predetermined time interval. The method then determines an occurrence of a LDP flapping event using the plurality of total numbers.
