Abstract
A method and system for identifying the root-cause event that affected a path change in a multi-area Internet protocol (IP) autonomous system (AS) operated according to a link state routing protocol such as the Open Shortest Path First (OSPF) protocol is disclosed. The method and system may enable a user, such as a network administrator, to explicitly identify which routing protocol events are responsible for changes to paths that are being monitored.
