Abstract
A method and apparatus for providing a wide area network infrastructure for providing services on IP networks such as Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) networks are disclosed. For example, an enterprise customer may subscribe to a service for obtaining a reliable wide area network infrastructure for communicating among two or more customer locations. The network service provider creates a virtual private network in the public domain and another virtual private network in the private domain to interconnect the customer locations. It then connects each customer edge router to two provider edge routers one in each domain and/or instances of provider edge functionality in each domain. Routes are then advertised via two control planes to both virtual private networks.
