1. A method comprising:
receiving, at an SD-WAN controller for an SD-WAN, data regarding routes available to reach respective edge network devices in the SD-WAN;
selecting, for a first edge network device in the SD-WAN, a subset of second routes available to reach a second edge network device based on compatibility of first routes available to the first edge network device and the subset of the second routes available to the second edge network device, where the compatibility is based on compatibility of transport routes associated with the first routes and the second routes, and wherein the compatibility of transport routes is determined from a transport compatibility matrix, wherein the transport compatibility matrix is pre-calculated in an offline process and includes compatible and incompatible transport routes; and
advertising the subset of the second routes available to reach the second edge network device from the first edge network device to the first edge network device.
