Cloud Enterprise Network:CreateTransitRouterVbrAttachment

Last Updated:Jan 11, 2023

Creates a virtual border router (VBR) connection on an Enterprise Edition transit router.

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 create a VBR connection on 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 ID of the VBR connection is returned but the operation is still being performed in the system background. You can call ListTransitRouterVbrAttachments to query the status of a VBR connection.

    • If a VBR 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.

Authorization information

The following table is the authorization information corresponding to the API, which can be found in the RAM permission policy statement.Action Used in the element to grant the RAM user or RAM role permission to call this API. The specific instructions are as follows:

  • 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 keyword: refers to the condition keyword defined by the cloud product itself.
  • 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.
