Abstract
A method is implemented by a network element or controller for determining a backup path for a fast reroute process to be utilized in response to a network event invalidating a primary path to a destination node. The method identifies at least one intermediate node that has a backup loop free alternative (LFA) path to a destination node in a network where no path meeting LFA conditions can be found for a point of local repair (PLR).
