Abstract: Exemplary methods, apparatuses, and systems maintain network membership information for a host when it is disconnected from a controller. When the host detects a loss of connectivity with the network controller, the host identifies and selects one or more hosts that are members of a control logical network. The control logical network includes hosts configured to run data compute nodes that are members of the overlay network, regardless of whether or not each of the hosts is currently running a data compute node that is a member of the overlay network. The host then sends any broadcast, unknown destination, or multicast (BUM) data packet(s) to the selected one or more hosts.
