1. A method of implementing logical networks on a plurality of shared managed forwarding elements, the method comprising:
configuring a plurality of software forwarding elements executing on a first plurality of host computers to implement a logical forwarding element of a logical network, the first plurality of host computers executing a first plurality of machines connected to the logical network;
to connect a second plurality of machines executing on a second plurality of host computers that do not have software forwarding elements configured as one or more logical forwarding elements of the logical network, configuring a set of top-of-rack (TOR) switches to be part of the logical network so as to connect the first and second plurality of machines, said set of TOR switches communicatively coupled to the second plurality of host computers, wherein configuring the set of TOR switches comprises providing the set of TOR switches with mapping records that map a virtual local area network (VLAN) used by one or more host computers in the second plurality of host computers to the logical network.
