Abstract
A method for configuring a managed hardware forwarding element (MHFE) to perform packet forwarding operations for a logical network is described. The method receives data for the logical network that defines a logical router and a set of logical switches for logically connecting several end machines that operate on different host machines to several physical machines that are connected to the MHFE. The method defines multiple routing components for the logical router, where each routing component includes a separate set of logical ports. The method then configures a forwarding table on the MHFE by populating the forwarding table with tunnel endpoint data for each logical port of each routing component of the logical router that is associated with a logical port of a logical switch. The tunnel endpoint data populated for logical ports of one routing component indicate that no tunnel should be established for any of the logical ports.
