Abstract
Some embodiments provide a method for a network controller operating on a host machine that hosts a particular one of multiple centralized routing components for a logical router. The method receives a routing table from a routing protocol application operating on the host machine. Each of the other centralized routing components operates on a different host machine and implements a different interface of the logical router that connects to at least one physical router external to the logical network. The routing protocol application operates as a router server for all of the centralized routing components. For each of the other centralized routing components, the method identifies a set of routes in the routing table to distribute to the centralized routing component. The method sends the identified routes for each centralized routing component to the centralized routing component.
