Abstract: An example includes a manager gateway of a gateway cluster, comprising processing circuitry and a memory including instructions that cause the gateway to generate a virtual IP address for each gateway of the gateway cluster. The instructions further cause the gateway to receive an indication that a client device has joined a LAN. The instructions further cause the gateway to determine an anchor gateway to which the client device is to be anchored. The instructions further cause the gateway to transmit a first message anchoring the client device to the anchor gateway. The instructions further cause the gateway to transmit a second message offering an address to the client device.

Abstract: An example network orchestrator includes processing circuitry and a memory including instructions that, when executed by the processing circuitry, cause the network orchestrator to determine that a branch site of a WAN includes multiple branch gateways. The network orchestrator further determines that devices of a core site of the WAN and devices of the branch site are members of an extended VLAN. The network orchestrator further transmits a first command to a first branch gateway and a first headend gateway to establish a WAN uplink tunnel to forward data traffic of the extended VLAN. The network orchestrator further transmits a second command to a set of branch gateways of the branch gateway cluster to establish intracluster tunnels with the first branch gateway.

Abstract: An example network orchestrator of a SD-WAN is configured to classify, based on operating health information, each branch gateway of a cluster in an operating health class of a set of operating health classes. A bucketmap is generated based on the classifications of each branch gateway of the cluster. The bucket map may be transmitted to a leader branch gateway of the cluster. Each branch gateway may be reclassified in an operating health class. An updated bucketmap may be transmitted to a leader branch gateway.

Abstract: An example branch gateway includes processing circuitry, memory including instructions, and a plurality of ports. The branch gateway transmits, from a plurality of ports, a first broadcast message. The branch gateway receives, in response to the first broadcast message, response messages on respective ports. The branch gateway determines, based on a receipt order of the response messages, an identifying address from a first response message. The branch gateway assigns the respective port for each response message to a unique VLAN. The branch gateway determines, for each port assigned to a unique VLAN, a link health parameter. The branch gateway selects a primary port to connect to an activation server of a WAN. The branch gateway selects a secondary port to connect to the activation server.
