Configuration of a logical router for dynamic routing

A non-transitory machine readable medium storing a program which when executed by at least one processing unit configures a set of host machines that implements a logical router to exchange routing data with neighboring routers through a dynamic routing protocol, the logical router implemented as a plurality of routing components, the program comprising sets of instructions for:

• receiving identification data for a first physical router and a second physical router with which to peer the logical router;
• based on the identification data, identifying (i) a first subset of the routing components to peer with the first physical router and (ii) a second subset of the routing components to peer with the second physical router, the second subset comprising at least one routing component of the logical router that is not in the first subset;
• and
• generating configuration data for each routing component in the first and second subsets, wherein (i) each routing component in the first subset uses the configuration data to exchange routing data with the first physical router through the dynamic routing protocol and (ii) each routing component in the second subset uses the configuration data to exchange routing data with the second physical router through the dynamic routing protocol.

• receiving identification data for the neighboring router with which to peer the logical router, wherein the neighboring router is more than one hop away from the logical router;
• identifying routing data for the plurality of routing components;
• based on the identification data and the routing data, identifying a subset routing components to peer with the neighboring router;
• and
• generating configuration data for each routing component in the identified subset, wherein each identified routing component uses the configuration data to exchange routing data with the neighboring router through the dynamic routing protocol.
