Abstract
A controller includes a transceiver to establish a first session with a route reflector and monitor advertisements received by the route reflector from nodes in a network via second sessions established between the nodes and the route reflector. The controller also includes a processor to generate forwarding instructions for the nodes based on the advertisements. The forwarding instructions indicate one or more routes from a root node to one or more leaf nodes of a service. The transceiver provides the forwarding instructions to the root node. In some cases, the first session is established according to the border gateway protocol (BGP) and the one or more second sessions are established according to the BGP. The controller determines that the one or more leaf nodes are registered for one or more virtual private network (VPN) services based on the advertisements.
