Detach Transit Routers and Delete a CEN Instance via API - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Deletes a Cloud Enterprise Network (CEN) instance.

Operation description

DeleteCen is an asynchronous operation. After you send a request, the system returns a RequestId, but the CEN instance is not yet deleted. The deletion task continues to run in the background. You can call the DescribeCens operation to query the status of the CEN instance.

If the CEN instance is in the Deleting state, the CEN instance is being deleted. In this state, you can only query the CEN instance but cannot perform other operations on it.
If the CEN instance cannot be found, the CEN instance is deleted.

Before you begin

Before you delete a CEN instance, make sure that no bandwidth plans exist under the CEN instance, and no network instance connections or custom route tables exist under the transit router of the CEN instance:

To delete network instance connections, see:
Note
To delete network instance connections under a Basic Edition transit router, see DetachCenChildInstance.
To delete custom route tables of an Enterprise Edition transit router, see DeleteTransitRouterRouteTable.
To disassociate a bandwidth plan from a CEN instance, see UnassociateCenBandwidthPackage.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.

Error codes

HTTP status code	Error code	Error message	Description
400	OperationFailed.DeleteCenWithCustomRouteTable	Operation failed because you are not allowed to delete the CEN with the custom transit router route table.	The error message returned because you are not allowed to delete the CEN instance unless all custom route tables are deleted from the CEN instance.
400	OperationFailed.DeleteCenWithRouteEntry	Operation failed because you are not allowed to delete the CEN with the transit router route entry.	The error message returned because you are not allowed to delete the CEN instance unless all custom route entries are deleted from the CEN instance.
400	OperationFailed.MulticastDomainExist	Operation is invalid because multicast domain exists.	The error message returned because the transit router is associated with a multicast domain. Disassociate the transit router from the multicast domain before you delete the transit router.
400	OperationFailed.PrefixListAssociationExist	Operation is invalid because prefixList association exists.	The transit router has associated route prefixes. Delete them and try again.
400	OperationFailed.AggregationRouteExist	Operation is invalid because transit router aggregation route exists.	The delete operation failed because aggregate routes exist.
400	OperationFailed.TrafficMarkingPolicyExist	Operation is invalid because transit router traffic marking policy exists.	The transit router has traffic marking policies. Delete the traffic marking policies and retry.
400	OperationUnsupported.action	This action is not support.	The error message returned because this operation is not supported in the specified region.
400	InvalidParameter	Invalid parameter.	The error message returned because the parameter is set to an invalid value.
400	Unauthorized	The AccessKeyId is unauthorized.	The error message returned because you do not have the permissions to perform this operation.
400	OperationFailed.TrafficQosPolicyExist	Operation is invalid because traffic qos policy exists.	The error message returned because this operation is not supported when a QoS policy exists. Delete the QoS policy and try again.
400	InvalidOperation.RelatedEcrExists	Operation is invalid due to related ECR exists.
400	InvalidParameter.CenId	The specified parameter CenId is invalid.
