Cloud router platform for sdn networks

Abstract

A system is described whereby a cloud router may allow routing as a service in a cloud-like manner. In an example, an apparatus may include a processor and a memory coupled with the processor that effectuates operations. The operations may include receiving first routing information associated with a first customer edge device; adding the first routing information to network routing information of the apparatus, wherein the network routing information comprises a network routing table with routes for a plurality of networks; and propagating the network routing information to a software defined network (SDN) controller, wherein, based on the network routing information, the SDN controller sends a forwarding information base (FIB) to a provider edge device connected with the first customer edge device.
