DeleteTransitRouterPrefixListAssociation - Cloud Enterprise Network

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transit router from a prefix list, the routes that point to the CIDR blocks in the prefix list are automatically withdrawn from the route table.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.

Debugging

You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

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
