    Cloud Enterprise Network:CreateTransitRouter

    最終更新日:Nov 18, 2024

    Creates an Enterprise Edition transit router.

    Operation description

    • You can call CreateTransitRouter to create an Enterprise Edition transit router. For more information about the regions that support Enterprise Edition transit routers, see What is CEN?

    • CreateTransitRouter is an asynchronous operation. After you send a request, the transit router ID is returned but the operation is still being performed in the system background. You can call ListTransitRouters to query the status of an Enterprise Edition transit router.

      • If an Enterprise Edition transit router is in the Creating state, the Enterprise Edition transit router is being created. In this case, you can query the Enterprise Edition transit router but cannot perform other operations.
      • If an Enterprise Edition transit router is in the Active state, the Enterprise Edition transit router 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.

    Request parameters

    ParameterTypeRequiredDescriptionExample
    ClientTokenstringNo

    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, the system automatically uses RequestId as ClientToken. The value of RequestId of each API request is different.
    		02fb3da4-130e-11e9-8e44-001****
    CenIdstringYes

    The ID of the Cloud Enterprise Network (CEN) instance.

    		cen-j3jzhw1zpau2km****
    RegionIdstringYes

    The ID of the region where the Enterprise Edition transit router is deployed.

    You can call the DescribeChildInstanceRegions operation to query the most recent region list.

    		cn-zhangjiakou
    TransitRouterNamestringNo

    The name of the Enterprise Edition transit router.

    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
    TransitRouterDescriptionstringNo

    The description of the Enterprise Edition transit router instance.

    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
    DryRunbooleanNo

    Specifies whether to check the request without performing the operation. Check items include permissions and the status of the specified cloud resources. Valid values:

    • false (default): sends the request. If the request passes the check, an Enterprise Edition transit router is created.
    • true: checks the request but does not create the Enterprise Edition transit router. If you use this value, the system checks whether the required parameters are set, and whether the request syntax is valid. If the request fails the check, an error message is returned. If the request passes the check, the DryRunOperation error code is returned.
    		false
    SupportMulticastbooleanNo

    Specifies whether to enable the multicast feature for the Enterprise Edition transit router. Valid values:

    • false (default): no
    • true: yes

    The multicast feature is supported only in specific regions. You can call ListTransitRouterAvailableResource to query the regions that support multicast.

    		false
    TransitRouterCidrListarray<object>No

    The CIDR blocks to be added to the transit router.

    objectNo

    The CIDR blocks to be added to the transit router.

    You can specify at most five CIDR blocks in each call. For more information about CIDR blocks of transit routers, see CIDR blocks of transit routers.

    Note Only Enterprise Edition transit routers support CIDR blocks.
    CidrstringNo

    The CIDR block of the transit router.

    		192.168.10.0/24

    The description must be 1 to 256 characters in length.

    		desctest
    PublishCidrRoutebooleanNo

    Specifies whether to allow the system to automatically add a route that points to the CIDR block to the route table of the transit router.

    • true (default)

      If you set the value to true, after you create a VPN attachment on a private VPN gateway and enable route learning for the VPN attachment, the system automatically adds the following route to the route table of the transit router that is in route learning relationship with the VPN attachment:

      A blackhole route whose destination CIDR block is the transit router CIDR block, which refers to the CIDR block from which gateway IP addresses are allocated to the IPsec-VPN connection.

      The blackhole route is advertised only to the route tables of virtual border routers (VBRs) connected to the transit router.
