DeleteTransitRouterPrefixListAssociation - Cloud Enterprise Network - Alibaba Cloud ドキュメントセンター

Disassociates the route table of an Enterprise Edition transit router from a prefix list.

Operation description

After you disassociate a route table of an Enterprise Edition transit router from a prefix list, the routes that point to the CIDR blocks in the prefix list are automatically withdrawn from the route table. Before you disassociate the route table of an Enterprise Edition transit router from a prefix list, you must migrate workloads that use the routes in case services are interrupted.

RAM authorization

The table below describes the authorization required to call this API. You can define it in a 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 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. For more information, see Common condition keys.
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 all requests. The token can contain only ASCII characters. Note If you do not set this parameter, ClientToken is set to the value of RequestId. The value of RequestId for each API request may be different.	123e4567-e89b-12d3-a456-4266****
RegionId	string	Yes	The ID of the region where the transit router is deployed. You can call the DescribeChildInstanceRegions operation to query the most recent region list.	cn-hangzhou
TransitRouterId	string	Yes	The ID of the transit router.	tr-6ehx7q2jze8ch5ji0****
PrefixListId	string	Yes	The ID of the prefix list.	pl-6ehtn5kqxgeyy08fi****
TransitRouterTableId	string	Yes	The ID of the route table of the transit router.	vtb-6ehgc262hr170qgyc****
NextHop	string	Yes	The ID of the next hop. Note If NextHopType is set to BlackHole, you must set this parameter to BlackHole.	tr-attach-flbq507rg2ckrj****
NextHopType	string	No	The type of the next hop. Valid values: BlackHole: All the CIDR blocks in the prefix list are blackhole routes. Packets destined for the CIDR blocks are dropped. VPC: The next hop of the CIDR blocks in the prefix list is a VPC connection. VBR: The next hop of the CIDR blocks in the prefix list is a VBR connection. TR: The next hop of the CIDR blocks in the prefix list is an inter-region connection.	VPC
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 limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the `DryRunOperation` error code is returned. false (default): performs a dry run and sends the task.	false
