Dissociate a transit router attachment from a route table using DissociateTransitRouterAttachmentFromRouteTable - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Dissociates a network instance connection from a route table.

Operation description

DissociateTransitRouterAttachmentFromRouteTable is an asynchronous operation. After you send a request, the system returns a RequestId but the dissociation between the network instance connection and the route table is not complete. The dissociation task continues to run in the background. You can call ListTransitRouterRouteTableAssociations to query the association status between the network instance connection and the route table.

If the association status is Dissociating, the network instance connection is being dissociated from the route table. In this state, you can only query the forwarding association between the network instance connection and the route table. You cannot perform other operations.
If the ListTransitRouterRouteTableAssociations operation does not return the forwarding association between the network instance connection and the route table, the dissociation is successful.

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
TransitRouterAttachmentId	string	Yes	The ID of the network instance connection.	tr-attach-nls9fzkfat8934****
TransitRouterRouteTableId	string	Yes	The ID of the Enterprise Edition transit router route table.	vtb-bp1dudbh2d5na6b50****
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****
DryRun	boolean	No	Specifies whether to perform a dry run, including permission and instance status verification. Valid values: false (default): Sends a normal request and dissociates the forwarding association after the request passes the check. true: Sends a check request. Only the check is performed. The forwarding association is not dissociated. 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
