Use ReplaceTransitRouterRouteTableAssociation to replace the route table associated with a network instance connection - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Operation description

Only network instance connections under an Enterprise Edition transit router support changing the associated transit router route table.
ReplaceTransitRouterRouteTableAssociation is an asynchronous operation. After you send a request, the system returns a RequestId, but the transit router route table associated with the network instance connection has not been replaced yet. The replacement task is still running in the background. You can call ListTransitRouterRouteTableAssociations to query the association forwarding status between the network instance connection and the new transit router route table.
- If the association forwarding status is Replacing, the network instance connection is changing the associated transit router route table. In this state, you can only query the association forwarding relationship between the network instance connection and the transit router route table. You cannot perform other operations.
- If the association forwarding status is Active, the network instance connection has successfully changed the associated transit router route table.

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.	123e4567-e89b-12d3-a456-426655****
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: performs a dry run. The system checks the required parameters, request syntax, and business restrictions. If the request fails the dry run, the corresponding error is returned. If the request passes the dry run, the error code `DryRunOperation` is returned. The transit router route table associated with the network instance connection is not replaced. false (default): performs the actual request. If the request passes the check, the transit router route table associated with the network instance connection is directly replaced.	false
TransitRouterAttachmentId	string	Yes	The ID of the network instance connection.	tr-attach-071g5j5tefg4x6****
TransitRouterRouteTableId	string	Yes	The ID of the transit router route table to be associated with the network instance connection.	vtb-bp1cprmc6xmzjd66i****
