When you enable route redistribution, the tier-0 logical router starts sharing specified routes with its northbound router.

Prerequisites

  • Verify that the tier-0 and tier-1 logical routers are connected so that you can advertise the tier-1 logical router networks to redistribute them on the tier-0 logical router. See Attach Tier-0 and Tier-1.

  • If you want to filter specific IP addresses from route redistribution, verify that route maps are configured. See Create a Route Map.

  2. Select Routing from the navigation panel.
  3. Select the tier-0 logical router.
  4. Click the Routing tab and select Route Redistribution from the drop-down menu.
