Last-Hop Processing for Reverse Direction Packets

For a first managed forwarding element, a method comprising:

• receiving a first packet from a second managed forwarding element, the first packet comprising context information that identifies (i) that first-hop logical processing was performed by the second managed forwarding element to process the first packet through a logical network and (ii) that a first machine connected to the first managed forwarding element is a destination for the first packet;
• based on the first packet, generating forwarding data for processing subsequent packets received from the first machine with a particular destination address that corresponds to a source address of the first packet;
• and
• using the generated forwarding data to forward a second packet, received from the first machine with the particular destination address, to the second managed forwarding element without performing first-hop logical processing on the second packet.

A non-transitory machine readable medium storing a first managed forwarding element for execution by at least one processing unit, the first managed forwarding element comprising sets of instructions for:

• receiving a first packet from a second managed forwarding element, the first packet comprising context information that identifies (i) that first-hop logical processing was performed by the second managed forwarding element to process the first packet through a logical network and (ii) that a first machine connected to the first managed forwarding element is a destination for the first packet;
• based on the first packet, generating forwarding data for processing subsequent packets received from the first machine with a particular destination address that corresponds to a source address of the first packet;
• and
• using the generated forwarding data to forward a second packet, received from the first machine with the particular destination address, to the second managed forwarding element without performing first-hop logical processing on the second packet.
