Abstract:
1. A non-transitory computer-readable storage medium storing instructions that when executed by a computer cause the computer to perform a method for exchanging routing information, the method comprising: receiving, by a master node in a network having at least one master node and a plurality of client nodes which are each separate routing entities, a first interface state change message from a first client node, the first interface state change message indicating a change in an interface associated with the first client node; starting, by the master node responsive to receiving the first interface state change message, a link state database (LSD) update timer having a predetermined time interval; receiving, by the master node, one or more additional interface state change messages from the plurality of client nodes during the predetermined time interval; responsive to a determination that the LSD update timer has expired, updating, by the master node, an LSD based on the first interface state change message and the one or more additional received interface state change messages; and transmitting, by the master node to each client node of the plurality of client nodes, an LSD update message, wherein the LSD update message causes each client node of the plurality of client nodes to update a respective copy of the link state database.
