Abstract: A system provisions global logical entities that facilitate the operation of logical networks that span two or more datacenters. These global logical entities include global logical switches that provide L2 switching as well as global routers that provide L3 routing among network nodes in multiple datacenters. The global logical entities operate along side local logical entities that are for operating logical networks that are local within a datacenter.

Abstract: Some embodiments provide a method or tool for automatically configuring a logical router on one or more edge nodes of an edge cluster (e.g., in a hosting system such as a datacenter). The method of some embodiments configures the logical router on the edge nodes based on a configuration policy that dictates the selection method of the edge nodes. In some embodiments, an edge cluster includes several edge nodes (e.g., gateway machines), through which one or more logical networks connect to external networks (e.g., external logical and/or physical networks). In some embodiments, the configured logical router connects a logical network to an external network through the edge nodes.

Abstract: Some embodiments provide a method for configuring a set of logical routers in a logical network. The method receives a configuration of an advertised route for a first logical router and a set of allowable routes for a second logical router to which the first logical router connects. The method determines whether the set of allowable routes for the second logical router includes the advertised route as an allowed route from the first logical router. Only when the advertised route is an allowed route from the first logical router, the method adds the advertised route to a routing table for at least one component of the second logical router.

Abstract: Some embodiments provide a method for implementing a logical router in a logical network. In some embodiments, the method receives a configuration of a static route for the logical router, which includes several routing components with separate routing tables. The method identifies which of the routing components require addition of a route to a corresponding routing table to implement the configuration of the static route. The method adds the routes to the corresponding separate routing tables of the identified routing components.

Abstract: Some embodiments provide a method for configuring a logical router in a logical network. The method receives a configuration of a rule for network address translation (NAT) used by a first logical router to translate a set of network addresses to a particular network address. The method automatically configures advertisement of a route for the particular network address to a second logical router. The method automatically adds the advertised route for the particular network address to a routing table for at least one component of the second logical router.
