Abstract
Disclosed is a first device and a second device each sending BFD echo request packets in an initial stage of establishing communication between the two devices. A method can include determining that a certain mode is detected, such as a low bandwidth mode. The method can be practiced by one or both of the devices or a separate network controller. Based on the detection of the certain mode or the communication link being in a certain mode, the method includes the first device or the second device electing to be a master or a slave. Upon establishing that one of the devices is the master and the other of the devices is a slave, only the master will send BFD echo request packets.
