1. A network comprising:
a set of host computers each executing a set of virtual machines (VMs) and a managed physical routing element (MPRE) that implements a logical router with a plurality of MPREs executing on a plurality of other host computers;
a plurality of routers operating outside of the house computers in the set of host computers;
wherein a plurality of MPREs in a subset of the plurality of host computers are selected to respond to address resolution protocol (ARP) messages sent by the routers and to perform logical routing for the logical router on data packets from the plurality of routers to the VMs executing on the host computers in the set of host computers.
