Abstract
In some embodiments, a method receives a selection of a logical router in the first computing device in a first site of a plurality of sites as a preferred egress point to an external network for the logical router. The logical router is instantiated on computing devices in the plurality of sites and a single site in the sites is the preferred egress point for the logical router. The method stores identification information for the logical router in a routing table that stores identification information for multiple logical routers. The identification information is unique among multiple logical routers. The method advertises via a routing instance in a control plane to other computing devices in other sites the identification information for the logical router to indicate the logical router in the first computing device in the first site is the preferred egress point.
