Creates an inter-region connection on an Enterprise Edition transit router.
Operation Description
You must purchase a bandwidth plan before you can create an inter-region connection. For more information, see CreateCenBandwidthPackage.
CreateTransitRouterPeerAttachment is an asynchronous operation. After you send a request, the system returns an inter-region connection ID and runs the task in the background. You can call the ListTransitRouterPeerAttachments operation to query the status of an inter-region connection.
- If an inter-region connection is in the Attaching state, the inter-region connection is being created. You can query the inter-region connection but cannot perform other regions.
- If an inter-region connection is in the Attached state, the inter-region connection is created.
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 Resourcesis 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.
