Abstract
A device may receive an indication to generate a probe packet associated with a tunnel included in a first network. The tunnel may include a first tunnel endpoint and a second tunnel endpoint and may correspond to a path, associated with a second network, between the first tunnel endpoint and the second tunnel endpoint. The device may generate the probe packet including information associated with the tunnel. The device may provide the probe packet, via the first tunnel endpoint, such that the probe packet is received by a network device that lies on the path. The device may receive a response packet, associated with the probe packet and provided by the network device, that includes path information. The path information may include information associated with the network device. The device may store the path information to allow the network device to be identified as lying on the path.
