Abstract:
A managed hardware forwarding element (MHFE) that performs packet forwarding operations for a logical network is described. The MHFE receives configuration 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 logical router also includes multiple routing components. The MHFE also receives a first forwarding table and a second forwarding table. The first forwarding table stores linking data for each logical port of each logical switch in the set of logical switches that identifies a corresponding routing component in the logical router. The second forwarding table stores a set of routes for each routing component of the logical router. The MHFE uses the first and second forwarding tables to perform packet forwarding operations at the MHFE.
