If local egress is enabled when a universal logical router is created, routes are sent to hosts only when the host locale ID matches the locale ID associated with the route. You can change the locale ID on a router, and this updated locale ID gets associated with all the static and dynamic routes on this router. The routes are sent to hosts and clusters with matching locale IDs.
See Cross-vCenter NSX Topologies for information on routing configurations for cross-vCenter NSX environments.
Prerequisites
The universal logical (distributed) router must have been created with local egress enabled.
