Abstract
A method for leader device selection in a control cluster using a shared virtual local area network (VLAN) is provided in the illustrative embodiments. A broadcast Hello packet is received from a sender virtual device over the VLAN at a first virtual device. When the first virtual device satisfies a partnership criterion specified in the Hello packet, a first ranking of the first virtual device is evaluated to be higher than a ranking of a sender virtual device. A first Live packet is unicast over the VLAN to the sender virtual device and a leadership role in the control cluster is taken by the first virtual device. The sender virtual device is caused to stop a broadcasting operation at the sender virtual device. A second Hello packet is broadcasted from the first virtual device over the VLAN.
