Some embodiments provide a method for a controller that manages a physical network that implements multiple logical networks that include multiple logical routers. The method receives a command to change a particular centralized routing component of a logical router to an inactive state. At least two centralized routing components of the logical router are implemented on at least two different host machines in the physical network. The method identifies a host machine on which the particular centralized routing component operates. Other centralized routing components of other logical routers also operate on the identified host machine. The method sends a message to the identified host machine to cause the particular centralized routing component to change to an inactive state, without modifying a state of the identified host machine or the other centralized routing components operating on the identified host machine.
