Abstract
A network device is provided. During operation, the network device receives control information associated with a control protocol running on a multi-chassis link aggregation group (MC-LAG) from a first link coupling a second network device of the MC-LAG. The network device determines whether the second network device is operational via a second link, which is separate from the first link. The network device determines a split in the MC-LAG in response to determining the unavailability of the first link and the availability of the second network device via the second link. The network device checks a set of selection conditions in a predetermined order based on respective sets of operational information associated with the network device and the second network device. The network device then selects the second network device for forwarding traffic of the MC-LAG in response to the set of selection conditions indicating the second network device.
