METHOD AND APPARATUS FOR PROVIDING A HIERARCHICAL STRUCTURE FOR ROUTING

摘要

A method and apparatus for providing a hierarchical structure for routing over packet networks are disclosed. The method first receives one or more packets from at least one customer endpoint device with a Customer Edge (CE) functionality, wherein said one or more packets are destined for a destination node. The method locates a route for routing said one or more packets by consulting an interface specific routing table. The method then forwards said one or more packets towards said destination node using said route.
