CreateCenChildInstanceRouteEntryToAttachment - Cloud Enterprise Network

Adds a route entry to a network instance and sets the next hop of the destination CIDR block to the transit router in the current region.

Operation description

You can add routes only to virtual private clouds (VPCs) or virtual border routers (VBRs) that are connected to an Enterprise Edition transit router.
By default, the next hop of the routes is the transit router connection, which is the connection between the VBR and the Enterprise Edition transit router. You cannot modify the next hop.
CreateCenChildInstanceRouteEntryToAttachment is an asynchronous operation. After you send a request, the system returns a request ID and runs the task in the background. You can call the DescribeRouteEntryList operation to query the status of a route.
- If a route is in the Pending state, the route is being created. You can query the route but cannot perform other operations.
- If a route is in the Available state, the route is created.

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.

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.	02fb3da4-130e-11e9-8e44-001****
DryRun	boolean	No	Specifies whether to perform a dry run to check information such as the permissions and the instance status. Valid values: false: performs a dry run and sends the request. true: performs a dry run. The system checks the required parameters and request syntax. 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. Note This parameter is not in use.	false
CenId	string	Yes	The CEN instance ID.	vpc-bp1n6cbxcszp55vxo****
TransitRouterAttachmentId	string	Yes	The ID of the network instance connection.	tr-attach-r1qhupkc19iadz****
RouteTableId	string	Yes	The ID of the route table configured on the network instance.	vrt-bp1msipdczo9lejup****
DestinationCidrBlock	string	Yes	The destination CIDR block of the route.	10.0.0.0/24
