Abstract

Some embodiments provide a managed network for implementing a logical switching element. The managed network includes several managed edge switching elements that are each for (1) receiving packets for forwarding through the logical switching element and (2) forwarding packets that are known to the managed edge switching element to other managed edge switching elements in the several managed edge switching elements. The managed network includes a set of managed non-edge switching elements for (1) receiving packets from the several managed edge switching elements that are unknown to a particular managed edge switching element in the several managed edge switching elements and (2) forwarding packets to the several managed edge switching elements that are unknown to the several managed edge switching elements.
