Patent ID: 7864713

Claim:
A data processing system for configuring routing devices in a network data processing system, the data processing system comprising: a memory having instructions encoded thereon; a bus connecting the memory to a processor; and a processor, wherein the processor executes the instructions: to identify a routing change in the network data processing system; responsive to identifying the routing change, to generate a node topology for a set of routing devices present in the network data processing system, wherein generating the node topology includes receiving a child message from a particular routing device in the routing devices, responsive to receiving the child message, returning a parent message to the particular routing device, and responsive to receiving the child message from the routing device, adding the particular routing device to the node topology, wherein child messages are sent in response to the routing devices receiving a reset message; to build a master network configuration table at a routing device within the set of routing devices, wherein the network configuration table contains configuration data from the routing devices in the node topology; and to broadcast the master network configuration table to the routing devices in the network data processing system.
