Abstract
A system and method is directed to updating a route table in a distributed routing platform, thereby enabling multiple routing protocols to be executed on different routing modules. A slave route distributor on one routing module is configured to receive a route from a local route table and flow manager. The slave route distributor communicates the route to a master route distributor on another routing module by way of an inter process communications protocol. The master route distributor provides the route to its local route table and flow manager, where a determination is made whether the route is a best route. If the route is a best route, the master route distributor updates its external routing table. The master route distributor also distributes the route to another slave route distributor on yet another routing module, where the route enables an update to a remote routing protocol, and routing table.
