Abstract
Some examples relate to determining routing decisions in a SD-WAN overlay. In an example, a controller in a SD-WAN overlay comprising a plurality of network nodes may receive respective routing and link information from a respective routing agent present on each network node of the plurality of network nodes. The controller may generate a Prefix tree based on the respective routing and link information received from the respective routing agent. The prefix tree may store prefixes along with respective prefix information. The controller may determine, for each prefix in the Prefix tree, a respective routing decision for each network node in the plurality of network nodes. The controller may distribute the respective routing decision to each network node in the plurality of network nodes in the SD-WAN overlay.
