You can configure a static route on the tier-0 router to external networks. After you configure a static route, there is no need to advertise the route from tier-0 to tier-1, because tier-1 routers automatically have a static default route towards their connected tier-0 router.

About this task

The static route topology shows a tier-0 logical router with a static route to the 10.10.10.0/24 prefix in the physical architecture. For test purposes, the 10.10.10.10/32 address is configured on the external router loopback interface. The external router has a static route to the 172.16.0.0/16 prefix to reach the app and web VMs.
