LOGICAL FORWARDING ELEMENT IDENTIFIER TRANSLATION BETWEEN DATACENTERS

Abstract:

Some embodiments provide a method for a computing device that implements a first logical network gateway in a first datacenter to process data messages between data compute nodes (DCNs) belonging to the logical network and operating in the first datacenter and DCNs belonging to the logical network and operating in a second datacenter. From a host computer in the first datacenter, the method receives a logical network data message encapsulated with a first tunnel header including a first virtual network identifier corresponding to a logical forwarding element of the logical network. The method removes the first tunnel header and encapsulates the logical network data message with a second tunnel header include a second virtual network identifier corresponding to the logical forwarding element. The method transmits the logical network data message encapsulated with the second tunnel header to a second logical network gateway in the second datacenter.
