Abstract:
In general, techniques described are for providing graceful restart procedures for network devices of label switched paths (LSPs) implemented with label stacks. For example, a restarting network device may include a processor coupled to a memory that executes software configured to: receive a path signaling message including a recovery object that defines a reverse path of the LSP from an egress network device of the LSP to the restarting network device, including at least an upstream label and a downstream label associated with the restarting network device; determine, based on the recovery object, the upstream label and the downstream label associated with the restarting network device; and instantiate a control plane state of the restarting network device based on the recovery object.
