1. A method for defining a centralized gateway component of a logical router, the method comprising:

  • for each of a plurality of uplinks configured for the logical router, assigning the uplink to a different gateway machine;

    for a first one of the uplinks, defining a first centralized gateway component of the logical router for implementation on a first gateway machine to which the first uplink is assigned;

    defining a first local interface for the first centralized gateway component configured according to the first uplink, the first local interface for the first centralized gateway component to forward traffic to a network external to the implementation of the logical router;

    defining a second interface for the first centralized gateway component configured according to a second uplink, the second interface for redirecting traffic processed according to the second uplink configuration to a second centralized gateway component implemented on a second gateway machine for the second centralized gateway component to forward the traffic to the external network;

    defining a distributed routing component of the logical router for implementation by a plurality of managed forwarding elements at a plurality of machines, the plurality of machines comprising at least the gateway machines to which the uplinks are assigned; and

    defining a third interface for the first centralized gateway component, the third interface for the first centralized gateway component to exchange traffic with the distributed routing component.
