Abstract
A system for routing packets that includes leaf network devices, spine network devices, and a border gateway protocol controller to perform a method for routing packets in a network. The method includes receiving packets at a leaf device and, using the destination IP address of the packet to determine to which spine network device the packet is to be sent. The spine network devices each include a non-overlapping portion of a routing table. The spine network devices include functionality to determine a route for the packet based on its destination IP address, to determine to which leaf network device the packet is to be sent, and to send the packet to the discovered leaf network device. The leaf network device that receives the packet includes functionality to, based on the destination MAC address of the packet, determine out of which leaf network device interface to send the packet.
