Abstract
An example method includes monitoring a layer two network with a first network device that operates within the network. The method also includes discovering a second network device that operates within the network by receiving an extended continuity check message (CCM) transmitted from the second network device. The extended CCM transmitted from the second network device indicates to other network devices that a service instance is available on the second network device, and includes an indication of one or more network devices from which the second network device has received CCMs for the service instance. The method further includes determining that bidirectional connectivity exists between the first network device and the second network device when the indication includes the first network device as one of the network devices from which the second network device has received CCMs for the service instance.
