Use DeleteTransitRouterPeerAttachment to delete an inter-region connection - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Calls the DeleteTransitRouterPeerAttachment operation to delete an inter-region connection from an Enterprise Edition transit router.

Operation description

The DeleteTransitRouterPeerAttachment operation is asynchronous. After you send a request, the system returns a RequestId but the inter-region connection is not immediately deleted. The deletion task continues to run in the background. You can call the ListTransitRouterPeerAttachments operation to query the status of the inter-region connection.

If the inter-region connection is in the Detaching state, the inter-region connection is being deleted. In this state, you can only query the inter-region connection but cannot perform other operations on it.
If the specified inter-region connection cannot be found, the inter-region connection is deleted.

When calling the DeleteTransitRouterPeerAttachment operation, make sure that the parameter values you specify are correct. If you specify incorrect parameter values, the system still returns a RequestId but does not delete the inter-region connection from the Enterprise Edition transit router.

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.

Request parameters

Parameter	Type	Required	Description	Example
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The client token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the RequestId of the API request as the ClientToken. The RequestId may be different for each API request.	02fb3da4-130e-11e9-8e44-001****
TransitRouterAttachmentId	string	Yes	The ID of the inter-region connection.	tr-attach-gyjhtx9sjsxhm6****
DryRun	boolean	No	Specifies whether to perform a dry run for this deletion request, including permission and instance status checks. Valid values: false (default): Sends a normal request. If the request passes the check, the inter-region connection is deleted. true: Sends a check request. Only the check is performed without actually deleting the inter-region connection. The check items include whether required parameters are specified and the request format. If the check fails, the corresponding error is returned. If the check passes, the corresponding request ID is returned.	false
Force	boolean	No	Specifies whether to force delete the inter-region connection. Valid values: false (default): Before deleting the inter-region connection, the system checks whether related resource dependencies exist, such as associated forwarding and route learning. If related dependencies exist, the deletion is not allowed and the corresponding error is returned. true: When deleting the inter-region connection, all related dependencies are deleted by default.	false
