Abstract

A non-transitory machine readable medium storing a program that configures a managed forwarding element to perform logical L2 switching and L3 routing is described. The program generates a first set of flow entries for configuring the first managed forwarding element to perform (1) a first logical L2 processing for a first logical L2 domain, (2) a logical L3 processing, (3) a load balancing processing to select a second managed forwarding element from a plurality of managed forwarding elements to which to forward packets and (4) a logical ingress L2 processing for a second logical L2 domain on the packets. The program generates a second set of flow entries for configuring the second managed forwarding element to perform a second logical L2 processing for a second logical L2 domain on the packets.

First claim

What is claimed is:

1. A non-transitory machine readable medium storing a program which when executed by at least one processing unit configures a plurality of managed forwarding elements (MFEs) to implement a logical L3 router and a plurality of logical L2 switches that each logically couple to a plurality of machines, the program comprising sets of instructions for:
for each MFE of a set of MFEs that implement a particular logical L2 switch, generating a first set of data record…
