Abstract
A method and apparatus for providing communication for virtual private networks in networks such as Voice over Internet Protocol (VoIP) and Service over Internet Protocol (SoIP) are disclosed. The present method enables Service Border Routers (SBRs) to perform mapping of VPN routes between two or more autonomous systems based on Virtual Route Forwarding (VRF) tables configured on each Autonomous System (AS). The method configures cross-connect tables in SBRs for coupling one or more VRF tables in one autonomous system with one or more VRF tables in other autonomous systems.
