Abstract
Some embodiments provide a novel method of configuring a managed hardware forwarding element (MHFE) that implements a logical forwarding element (LFE) of a logical network to handle address resolution requests (e.g., Address Resolution Protocol (ARP) requests) for multiple addresses (e.g., IP addresses) associated with a single network interface of the logical network. The method identifies a physical port of the MHFE with which the multiple addresses are to be associated. The physical port is coupled to an end machine (e.g., a virtual machine, server, container, etc.) of the logical network. The method then modifies associations stored at the MHFE to associate the physical port with the multiple addresses.
