Abstract
A method for managing a network controller cluster includes obtaining, by the network controller in a network controller cluster, network device state information (NDSI) from each network device of a plurality of network devices managed by the network controller cluster, storing the NDSI in a configuration file, receiving a notification that a second network controller in the network controller cluster has failed, wherein the second network controller has a role of primary network controller in the network controller cluster, making a first determination that a role of the network controller has changed to primary network controller in the network controller cluster, based on the first determination, loading the NDSI from the configuration file into a network controller state database on the network controller, and initiating operation of the network controller using the network controller state database.
