Enterprise Edition transit routers support custom route tables. After you create a custom route table, you can create associated forwarding correlations, route learning correlations, or custom routes in the route table. This helps you manage traffic in a more flexible manner.
Background information
Each Enterprise Edition transit router has one system route table and supports custom route tables. Each Basic Edition transit router has one system route table and does not support custom route tables. For more information about how to check the edition of a transit router, see View the edition of a transit router.
- The system automatically creates the system route table. When you create an Enterprise Edition transit router, the system automatically creates a system route table.
- You can manually create custom route tables. Custom route tables are similar to virtual
routing and forwarding (VRF) used by traditional routers. A custom route table is
isolated from the system route table and other custom route tables.
After you create a network instance connection, you can associate the network instance connection to a custom route table by creating an associated forwarding correlation. After you create an associated forwarding correlation, the transit router forwards the traffic of the network instance connection based on the custom route table.

Delete a custom route table
You can delete a custom route table that is no longer needed. You cannot delete the system route table.
- The custom route table does not contain associated forwarding correlations. For more information about how to delete associated forwarding correlations, see Delete an associated forwarding correlation.
- The custom route table does not contain route learning correlations. For more information about how to delete route learning correlations, see Delete a route learning correlation.
- The custom route table does not contain custom routes. For more information about how to delete custom routes, see Delete a custom route from a route table of an Enterprise Edition transit router.
- Log on to the CEN console.
- On the Instances page, find the CEN instance that you want to manage and click the instance ID.
- Choose , find the transit router that you want to manage, and then click the ID of the transit router.
- On the details page of the transit router, click the Route Table tab.
- In the left-side section, click the route table ID.
- In the Route Table Details section, click Delete.
- In the Delete Route Table message, click OK.
