摘要： A novel method for logically routing a packet between a source machine that is in a first logical domain and a destination machine that is in a second logical domain is described. The method configures a managed switching element as a second-level managed switching element. The method configures a router in a host that includes the second-level managed switching element. The method communicatively couples the second-level managed switching element with the router. The method causes the router to route a packet when the router receives a packet from the first logical domain that is addressed to the second logical domain.

摘要： Some embodiments provide a novel method for forwarding a packet at a managed switching element in a first domain. The method receives a packet from a local machine. The method encapsulates the packet with a first context identifier that identifies a first logical port of a first logical switching element that couples to machines in both the first domain and a second domain. The first logical port maps to a destination address of the packet. Based on a mapping of the first logical port to a second logical port of a second logical switching element that couples to machines in only the first domain, the method encapsulates the packet with a second context identifier that identifies the second logical port. The method transmits the twice-encapsulated packet out of a port of the managed switching element based on the second context identifier.
