Abstract
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.
