CreateTransitRouterRouteTable - Cloud Enterprise Network

Creates a custom route table for an Enterprise Edition transit router.

Operation description

Only Enterprise Edition transit routers support custom route tables. For more information about the regions and zones that support Enterprise Edition transit routers, see What is CEN?
CreateTransitRouterRouteTable is an asynchronous operation. After you send a request, the route table ID is returned but the operation is still being performed in the system background. You can call ListTransitRouterRouteTables to query the status of a route table.
- If a route table is in the Creating state, the route table is being created. In this case, you can query the route table but cannot perform other operations.
- If a route table is in the Active state, the route table 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.

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.

Operation	Access level	Resource type	Condition key	Associated operation

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 different requests. The client token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.	02fb3da4-130e-11e9-8e44-001****
TransitRouterRouteTableName	string	No	The name of the custom route table. The name must be 1 to 128 characters in length, and cannot start with http:// or https://. You can also leave this parameter empty.	testname
TransitRouterRouteTableDescription	string	No	The description of the custom route table. The description must be 1 to 256 characters in length, and cannot start with http:// or https://. You can also leave this parameter empty.	testdesc
TransitRouterId	string	Yes	The ID of the Enterprise Edition transit router.	tr-bp1su1ytdxtataupl****
DryRun	boolean	No	Specifies whether to precheck the request. Check items include permissions and the status of the specified cloud resources. Valid values: false (default): sends the request. If the request passes the precheck, the custom route table is created. true: prechecks the request but does not create the custom route table. If you use this value, the system checks the required parameters and the request syntax. If the request fails to pass the precheck, an error message is returned. If the request passes the check, the system returns the ID of the request.	false
Tag	array<object>	No	The tags. You can specify at most 20 tags in each call.
	object	No
Key	string	No	The tag key. The tag key cannot be an empty string. The tag key can be up to 64 characters in length and cannot start with `acs:` or `aliyun`. It cannot contain `http://` or `https://`. You can specify at most 20 tag keys.	test
Value	string	No	The tag value. The tag value can be 0 to 128 characters in length, and cannot start with `aliyun` or `acs:`. It cannot contain `http://` or `https://`. Each tag key must have a unique tag value. You can specify at most 20 tag values in each call.	tagtest
RouteTableOptions	object	No	The features of the route table.
MultiRegionECMP	string	No	Specifies whether to enable multi-region equal-cost multi-path (ECMP) routing. Valid values: disable(default) If multi-region ECMP routing is disabled, routes that are learned from different regions but have the same prefix and attributes select the transit router with the smallest region ID as the next hop. Region IDs are sorted in alphabetic order. The network latency and bandwidth consumption also vary based on the region. Proceed with caution. enable If multi-region ECMP routing is enabled, routes that are learned from different regions but have the same prefix and attributes form an ECMP route. The network latency and bandwidth consumption also vary based on the region. Proceed with caution.	disable

Error codes

HTTP status code	Error code	Error message	Description
400	InvalidTransitRouterId.NotFound	TransitRouterId is not found	The error message returned because the specified transit router ID (TransitRouterId) does not exist.
400	OperationFailed.CCNTrNotSupport	Operation failed because the CCN transit router does not support route table.	The error message returned because transit routers deployed in CCN regions do not allow you to create route tables.
400	DryRunOperation	Request validation has been passed with DryRun flag set.	The error message returned because the dry run request passed the precheck.
400	MissingParam.TransitRouterId	The parameter TransitrouterId is mandatory.	The error message returned because the TransitRouterId parameter is not set.
400	OperationFailed.BasicTrNotSupport	Operation failed because the Basic TransitRouter does not support RouteTable	The error message returned because this operation is not supported by Basic Edition transit routers.
400	IncorrectStatus.TransitRouter	TransitRouter status is invalid.	The error message returned because the status of the transit router does not support this operation. Try again later.
400	QuotaExceeded.TransitRouterRoutTable	TransitRouterRoutTable quota exceeded.	The error message returned because the number of route tables has reached the upper limit.
400	OperationUnsupported.MultiRegionEcmp	This region does not support MultiRegionEcmp.	-
400	InvalidParameter	Invalid parameter.	The error message returned because the parameter is set to an invalid value.
400	Unauthorized	The AccessKeyId is unauthorized.	The error message returned because you do not have the permissions to perform this operation.
