A Cloud Enterprise Network (CEN) Instance is a fundamental resource for building and managing integrated cloud networks. It contains one or more Transit Routers (TRs). These TRs connect to each other through Inter-region Connections, enabling communication between network instances across regions. You must create a CEN Instance before using a TR to connect your network instances.

Delete a CEN instance
Before you delete a CEN instance, review the following prerequisites:
No network instance connections are created on the transit router. For more information, see the following topics:
The transit router does not contain custom route tables. For more information, see Delete a custom route table.
The default route table of the transit router does not contain custom route entries, prefix lists, or aggregate routes. For more information, see the following topics:
The transit router is not associated with a multicast domain. For more information, see Delete a multicast domain.
The transit router is not associated with traffic marking policies. For more information, see Delete a traffic marking policy.
Ensure the instance has no associated bandwidth plans. For more information, see Disassociate a bandwidth plan from a CEN instance.
Log on to the CEN console.
On the Instances page, find the CEN instance to delete and click Delete in the Actions column.
