Abstract
Some embodiments provide a method for a computing device serving as a host machine in a logical network. The method executes several virtual machines that are in several different segments of the logical network. The method operates a managed physical routing element (MPRE) for routing data packets between different segments of the logical network. The MPRE includes several logical interfaces, each of which is for receiving data packets from a different segment of the logical network. Each of the logical interfaces is addressable by a network layer address. The method intercepts an Address Resolution Protocol (ARP) broadcast message when the destination address matches the network address of one of the logical interfaces. The method formulates an ARP reply to the ARP broadcast message.
