Patent attributes
Some embodiments of the invention provide a method for managing logical forwarding elements (LFEs) implemented by multiple physical forwarding elements (PFEs) operating on multiple devices, each LFE including multiple logical ports. On a host computer executing a particular machine connected to the LFE and a PFE implementing the LFE, the method identifies an address discovery message associating a particular network address of the particular machine with another network address of the particular machine. The method identifies an LFE logical port associated with the particular machine, stores in an encapsulation header an identifier that identifies this port, and then forwards the encapsulated message to a set of one or more devices implementing the LFE for the devices to use in processing data messages associated with the particular machine.
