Abstract

Some embodiments provide a method for defining a gateway component of a logical router. The method assigns each of several uplinks to different gateway machines. For one of the uplinks, the method defines a first centralized gateway component of the logical router for implementation on a first gateway machine to which the uplink is assigned. The method defines a first local interface for the first gateway component configured according to the uplink. The first local interface for the first gateway component forwards traffic to a network external to the implementation of the logical router. The method defines a second interface for the first gateway component configured according to a second uplink. The second interface is for redirecting traffic processed according to the second uplink configuration to a second centralized gateway component implemented on a second gateway machine. The second gateway component forwards the traffic to the external network.
