Abstract
Systems and methods for dynamic service-based load balancing in an SD-WAN are provided. According to one embodiment, a routing protocol daemon of an SDN controller within a spoke network receives a dynamically assigned subnet and associated attributes for a client device newly registered with the hub network. The routing protocol daemon tags the subnet with a route tag using a route map based on the received attributes meeting network administrator-defined match criteria for corresponding attributes associated with the route tag in the route map. The tagged subnet is communicated to an SD-WAN daemon of the SDN controller, which translates an SD-WAN service rule defined with reference to the route tag to an SD-WAN service rule defined with reference to the subnet. A load balancer associated with the spoke network is caused to perform load balancing of incoming network traffic in accordance with the translated SD-WAN service rule.
