Abstract
Techniques are described which apply a method for including a routing stack to provide a timely way to dynamically learn about route changes for an end to end system in the context of an adaptive private network (APN). By allowing learned routes to be assigned different services based on filtering rules, the APN can efficiently manage traffic through the WAN. Techniques for learning routes and to advertise the learned routes in different networks are also described. Upon an APN route change being detected in the APN, a route table is updated with the APN route change, wherein the route table contains routes in a local area network (LAN) and routes in a wide area network (WAN). The APN route change is selected from the route table and configured to a protocol for the LAN. The selected APN route change is advertised in the protocol to local routers in the LAN.
