Cloud Enterprise Network:CreateTransitRouterVbrAttachment

Last Updated:Mar 25, 2024

Connects the virtual border routers (VBRs) among which you want to establish network communication to the transit router in the region. Then, the transit router can exchange data between the VBR and CEN instance over private connections.

Operation description

  • For more information about the regions and zones that support Enterprise Edition transit routers, see What is CEN?

  • You can use the following methods to connect a VBR to an Enterprise Edition transit router:

    • If an Enterprise Edition transit router is already created in the region where you want to create a VBR connection, set the VbrId and TransitRouterId parameters.
    • If no Enterprise Edition transit router is created in the region where you want to create a VBR connection, set the VbrId, CenId, and RegionId parameters. Then, the system automatically creates an Enterprise Edition transit router in the specified region.
  • CreateTransitRouterVbrAttachment is an asynchronous operation. After you send a request, the system returns a VBR connection ID and runs the task in the background. You can call the ListTransitRouterVbrAttachments operation to query the status of a VBR connection.

    • If a VBR connection is in the Attaching state, the VBR connection is being created. You can query the VBR connection but cannot perform other operations.
    • If a VBR connection is in the Attached state, the VBR connection is created.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

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.
