A method is disclosed that is implemented by a router for executing an internet protocol fast reroute process in response to a network event invalidating a current route to a destination node without degrading forwarding plane functionality or performance caused by indirect forwarding information base lookups. The method comprises a set steps including receiving or generating the network event by the router, the network event associated with a network event identifier and looking up the network event identifier in an event table to determine routes that are affected by the network event. The method further includes determining whether a route with a fast reroute forwarding object is affected by the network event in the routing information base and overwriting a current next hop forwarding object using a backup next hop forwarding object in the forwarding information base.
