CreateTransitRouteTableAggregation - Cloud Enterprise Network

Creates an aggregate route.

Operation description

After you add an aggregate route to a route table of an Enterprise Edition transit router, the Enterprise Edition transit router advertises its routes only to route tables of virtual private clouds (VPCs) that are associated with a route table of the Enterprise Edition transit router and have route synchronization enabled.

Perform the following operations before you create an aggregate route. Otherwise, the Enterprise Edition transit router does not advertise routes to VPC route tables:

Associated forwarding is enabled between the VPCs and the Enterprise Edition transit router. For more information, see AssociateTransitRouterAttachmentWithRouteTable .
Route synchronization is enabled for the VPCs. For more information, see CreateTransitRouterVpcAttachment .

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.

Authorization information

The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

Operation: the value that you can use in the Action element to specify the operation on a resource.
Access level: the access level of each operation. The levels are read, write, and list.
Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
- The required resource types are displayed in bold characters.
- If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
Condition Key: the condition key that is defined by the cloud service.
Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.

Request parameters

Parameter	Type	Required	Description	Example
TransitRouteTableId	string	Yes	The ID of the route table of the Enterprise Edition transit router.	vtb-iq8qgruq1ry8jc7vt****
TransitRouteTableAggregationName	string	No	The name of the aggregate route. The name must be 1 to 128 characters in length, and can contain letters, digits, and the following special characters: , . ; / @ _ -. You can also leave the name empty.	nametest
TransitRouteTableAggregationCidr	string	Yes	The destination CIDR block of the aggregate route. Note The following CIDR blocks are not supported: CIDR blocks that start with 0 or 100.64. Multicast CIDR blocks, including 224.0.0.1 to 239.255.255.254.	192.168.10.0/24
TransitRouteTableAggregationScope	string	Yes	The scope of networks that you want to advertise the aggregate route. Set the value to VPC, which specified that the aggregate route is advertised to VPCs that are in associated forwarding relationship with a route table of the Enterprise Edition transit router and have route synchronization enabled.	VPC
TransitRouteTableAggregationDescription	string	No	The description of the aggregate route. The description must be 0 to 256 characters in length, and can contain letters, digits, and the following special characters: , . ; / @ _ -.	desctest
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 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.	02fb3da4-130e-11e9-8e44-001****
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: false (default): 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.	false
