Abstract
A detection technique detects inconsistencies in forwarding databases of a router and its neighbor, i.e., a next-hop router, during routing transients in a computer network. The technique enables the router to detect when its view of a computed path to a destination station is inconsistent with the view of its neighbor along that path. Upon detecting such an inconsistent state, the router invokes one of a plurality of forwarding mechanisms with respect to a packet intended for the destination station in an attempt to suppress forwarding loops that may arise during the transients.
