CreateTransitRouterRouteTable - Cloud Enterprise Network

Calls the CreateTransitRouterRouteTable operation to create a custom route table for an Enterprise Edition transit router.

Operation description

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

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (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 Alibaba Cloud Resource Name (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.
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. Generate a token from your client to ensure that the token is unique among different requests. The token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the RequestId of the request as the ClientToken. The RequestId of each request is different.	02fb3da4-130e-11e9-8e44-001****
TransitRouterRouteTableName	string	No	The name of the custom route table. The name can be empty or 1 to 128 characters in length. It cannot start with `http://` or `https://`.	testname
TransitRouterRouteTableDescription	string	No	The description of the custom route table. The description can be empty or 1 to 256 characters in length. It cannot start with `http://` or `https://`.	testdesc
TransitRouterId	string	Yes	The ID of the Enterprise Edition transit router instance.	tr-bp1su1ytdxtataupl****
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: performs a dry run. The system checks the request for potential issues, including required parameters, request format, and service 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 request. If the request passes the dry run, a custom route table is created.	false
Tag	array<object>	No	The tag. You can specify up to 20 tags in each call.
	object	No
Key	string	No	The tag key of the resource. The tag key cannot be an empty string. The tag key can be up to 64 characters in length and cannot start with `aliyun` or `acs:`. It cannot contain `http://` or `https://`. You can specify up to 20 tag keys.	test
Value	string	No	The tag value of the resource. The tag value can be an empty string or a string of up to 128 characters. It cannot start with `aliyun` or `acs:` and cannot contain `http://` or `https://`. Each tag key must have a unique tag value. You can specify up to 20 tag values.	tagtest
RouteTableOptions	object	No	The features of the route table.
MultiRegionECMP	string	No	The multi-region equal-cost multi-path (ECMP) routing feature. Valid values: disable (default): disables the multi-region ECMP routing feature. If you disable the multi-region ECMP routing feature, 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. The region ID is sorted in alphabetical order. In this case, the latency and bandwidth consumption of the traffic may change. Make sure that you are aware of the impact before you disable the feature. enable: enables the multi-region ECMP routing feature. If you enable the multi-region ECMP routing feature, routes that are learned from different regions but have the same prefix and attributes are considered ECMP routes. In this case, the latency and bandwidth consumption of the traffic may change. Make sure that you are aware of the impact before you enable the feature.	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.
