Abstract
An approach is provided for improving network restoration by enhancing loop free alternative coverage. A loop-free alternate (LFA) procedure is initiated for a failed link of a network including a plurality of nodes. A state of incomplete loop-free alternate coverage for the nodes is determined. A shortest path in the network exclusive of the nodes associated with the failed link is determined. Each node along the determined shortest path is set as an explicit route object to create a bypass label switched path for the network.
