Abstract
Systems and methods for computing forward and reverse paths and checking the liveness, keep-alive status, or continuity of the forward and reverse paths are provided. A method, according to one implementation, includes the step of creating one or more messages related to a computation of a forward path from a head-end node to a tail-end node and a computation of a reverse path from the tail-end node to the head-end node. The method also includes the step of adding a data object to the one or more messages, the data object including an intent to check the liveness of the forward path and reverse path.
