Abstract
Some embodiments provide a method for a network controller in a network control system that manages a plurality of logical networks. The method receives a specification of a logical network that comprises a logical router with a logical port that connects to an external network. The method selects several host machines to host a L3 gateway that implements the connection to the external network for the logical router from a set of host machines designated for hosting logical routers. The method generates data tuples for provisioning a set of managed forwarding elements that implement the logical network to send data packets that require processing by the L3 gateway to the selected host machines. The data tuples specify for the managed forwarding elements to distribute the data packets across the selected host machines.
