Abstract: A method of recovering a fault in a multilayer network and an apparatus thereof are provided, the method including obtaining lower layer backup path setting information through a signaling message that is used for a label based path setting, setting a backup path at a lower layer based on the obtained lower layer backup path setting information, and upon detecting a fault at the lower layer, performing a protection switching through the set backup path at the lower layer.
