    Cloud Enterprise Network:CreateTransitRouterVbrAttachment

    Last Updated:Nov 18, 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 create a VBR connection on an Enterprise Edition transit router:

      • If an Enterprise Edition transit router is already created in the region, specify the VbrId, RegionId, and TransitRouterId parameters to create a VBR connection.
      • If no Enterprise Edition transit router is already created in the region, specify the VbrId, CenId, and RegionId parameters to create a VBR connection. When you create a VBR connection, the system automatically creates an Enterprise Edition transit router in the specified region.

    • CreateTransitRouterVbrAttachment is an asynchronous operation. After a request is sent, the system returns a request ID and runs the task in the background. You can call ListTransitRouterVbrAttachments to query the status of a VBR connection.

      • If the VBR connection is in the Attaching state, the VBR connection is being created. In this case, you can query the VBR connection but cannot perform other operations.
      • If the VBR connection is in the Attached state, the VBR connection is created.

    • The transit router and the VBR must belong to the same Alibaba Cloud account.

    • Transit routers can connect to VBRs that belong to the same or a different Alibaba Cloud account. To connect a transit router to a VBR that belongs to a different Alibaba Cloud account, grant permissions on the VBR to the transit router. For more information, see Grant a transit router permissions on a network instance that belongs to another Alibaba Cloud account.

    • After you create a VBR connection, it is not in route learning or associated forwarding relationship with transit router route tables by default.

    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.
