U-Turn detour paths, though the head-end router of a primary label switched path (LSP), are configured and used to enable fast failover to a secondary LSP, while avoiding reserving bandwidth (e.g., on links unused by primary and secondary paths) unnecessarily.

A method of operating a network device is provided that includes receiving a message, determining whether the message is associated with a known label-switched path (LSP), enqueuing the message in a first queue on the network device in response to determining that the message is associated with a known label-switched path, and enqueuing the message in a second queue, different than the first queue, on the network device subsequent to determining that the message is associated with an unknown label-switched path. The method can further include determining whether there are any messages associated with a known label-switched path enqueued in the first queue and continuously processing messages associated with the known label-switched path before either a message is dequeued from the second queue or the program yields to allow other pending workloads or processes to run.
