1. A method comprising: providing a network topology configuration interface including one or more interface elements for configuring one or more route target groups; accessing a hybrid network topology configuration set comprising two or more route target groups (RTGs) configured with the network topology configuration interface, wherein each RTG comprises a topology type identifier, one or more site identifiers, one or more role identifiers associated with each of the site identifiers, and one or more route target identifiers, wherein at least one site identifier contained in a first RTG is also contained in a second RTG of the two or more RTGs, and wherein the first RTG comprises a different topology type identifier than the second RTG; generating one or more route target statements, based on the topology type identifier and role identifiers of the two or more RTGs, defining the export or import of network layer reachability information between one or more routing nodes in a hybrid virtual private network (VPN) topology; and transmitting the one or more route target statements to one or more routing nodes of the hybrid VPN topology.
