Methods and systems are disclosed for detection of reroute occurrences in segment routing enabled networks. In one embodiment, a method includes receiving, at a first node in a communications network, a test message comprising a header, where the header comprises one or more segment identifiers. This embodiment of the method further includes detecting a first indicator of a rerouted test path for the message and sending an outgoing message to a node determined using the header, where sending the outgoing message comprises including in the outgoing message a second indicator that the test message has been rerouted. An embodiment of a system includes a network interface adapted for data communication with one or more nodes of a communications network and a processor operably coupled to the network interface and adapted to implement an embodiment of the method.
