    Cloud Enterprise Network:CreateTransitRouterPeerAttachment

    Last Updated:Oct 22, 2024

    To connect network instances across regions, such as virtual private clouds (VPCs), virtual border routers (VBRs), and IPsec-VPN connections that are connected to transit routers, you must create an inter-region connection between the network instances that you want to connect. You can call the CreateTransitRouterPeerAttachment operation to create an inter-region connection on an Enterprise Edition transit router.

    Operation description

    • Enterprise Edition transit routers allow you to allocate bandwidth resources to inter-region connections by using the following methods:

      • Allocate bandwidth resources from a bandwidth plan:

        You must purchase a bandwidth plan, and then allocate bandwidth resources from the bandwidth plan to inter-region connections. For more information about how to purchase a bandwidth plan, see CreateCenBandwidthPackage .

      • Use pay-by-data-transfer bandwidth resources:

        You can set a maximum bandwidth value for an inter-region connection. Then, you are charged for the amount of data transfer over the connection. For more information, see Inter-region data transfer.

    • CreateTransitRouterPeerAttachment 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 the ListTransitRouterPeerAttachments operation to query the status of an inter-region connection.

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