Logical L3 Processing for L2 Hardware Switches

摘要

A method for configuring a managed forwarding element (MFE) to perform logical routing operations in a logical network on behalf of a hardware switch is described. The method of some embodiments receives data that defines a logical router that logically connects several different end machines operating on several different host machines to different physical machines that are connected to the hardware switch. The method, based on the received data, defines a number of routing components for the logical router. In some embodiments, the method then configures the MFE to implement the routing components in order to enable the MFE to perform logical routing operations on behalf of the hardware switch.

1. A method for configuring a managed forwarding element (MFE) to perform logical routing operations in a logical network on behalf of a hardware switch, the method comprising:
receiving data defining a logical router that logically connects a plurality of end machines operating on a plurality of host machines to a plurality of physical machines that are connected to the hardware switch; configuring an MFE that operates on one of the host machines to implement the logical router in order to enable the MFE to perform logical routing operations for the hardware switch; and configuring the hardware switch to, upon receiving an L3 packet from one of the plurality of physical machines, forward the L3 packet to the MFE to perform the logical routing operations on the L3 packet.
