ABSTRACT:
A system receives a packet at a first node. The packet is destined for a second node. The system identifies a full routing node from a plurality of network devices. The full routing node is capable of providing routing information for each of the nodes within the plurality of network devices. The plurality of network devices comprises a subset of nodes, and a subset of full routing nodes. The subset of nodes is not capable of providing routing information for each of the nodes within the plurality of network devices. The system transmits the packet to the full routing node for future transmission to the second node.
