ListTransitRouterRouteTableAssociations - Cloud Enterprise Network

Operation description

When you call the ListTransitRouterRouteTableAssociations operation, you must specify at least one of the following request parameters: TransitRouterRouteTableId and TransitRouterAttachmentId.

If you specify only TransitRouterRouteTableId, the operation queries the network instance connections that are associated with the specified route table of the Enterprise Edition transit router.
If you specify only TransitRouterAttachmentId, the operation queries the route tables of the Enterprise Edition transit router that are associated with the specified network instance connection.
If you specify both TransitRouterRouteTableId and TransitRouterAttachmentId, the operation queries the forwarding association between the network instance connection and the route table of the Enterprise Edition transit router.
- If a forwarding association exists between the network instance connection and the route table, the details of the forwarding association are returned.
- If no forwarding association exists between the network instance connection and the route table, the TransitRouterAssociations array is empty in the response.

Make sure that you provide valid parameter values when you call the ListTransitRouterRouteTableAssociations operation. If you provide an invalid parameter, the system returns a RequestId but does not query the forwarding associations for the route table of the Enterprise Edition transit router or the network instance connection.

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 support 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.
