Abstract
A method for creating a secure network is provided. The method comprises establishing an overlay domain to control routing between overlay edge routers based on an underlying transport network, wherein said establishing comprises running an overlay management protocol to exchange information within the overlay domain; in accordance with the overlay management protocol defining service routes that exist exclusively within the overlay domain wherein each overlay route includes information on at least service availability within the overlay domain; and selectively using the service routes to control routing between the overlay edge routers; wherein the said routing is through the underlying transport network in a manner in which said overlay routes is shared with the overlay edge routers but not with the underlying transport network via the overlay management protocol.
