摘要： A system and method for routing traffic from an ingress provider edge router to an egress provider edge router that eliminates the need to share state information between the ingress provider edge router and a plurality of core routers in a core network. The ingress provider edge router and egress provider edge router are each coupled to at least two core routers among the plurality of core routers in the core network, the ingress provider edge router learning routes with a next hop equal to an IP address of the egress provider edge router through an internal border gateway protocol (iBGP). The ingress provider edge router balances traffic flows on uplinks between the ingress provider edge router and the at least two core routers coupled to the ingress provider edge router without knowledge of network topology in the core network.

摘要： A backbone network may include first and second border routers and a route reflector. The first border router may provide data connectivity between the backbone network and a first regional network. The first border router may be configured to receive a notification of a change in status of an edge router of the first regional network, and the notification may be received according to a first routing protocol. The first border router may be further configured to redistribute the notification of the change in status of the edge router from the first routing protocol to a second routing protocol with the first and second routing protocols being different. The second border router may provide data connectivity between the backbone network and a second regional network. The route reflector may be coupled between the first and second border routers, and the route reflector may be configured to transfer the redistributed notification from the first border router to the second border router. Related routers, methods, and computer program products are also discussed.

摘要： 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.
