    Cloud Enterprise Network:CreateTransitRouterVpcAttachment

    最終更新日:Nov 21, 2024

    Attaches virtual private clouds (VPCs) that you want to connect to a transit router. After you attach the VPCs to the same transit router, the VPCs can communicate with each other.

    Operation description

    • You can use the following methods to create a VPC connection from an Enterprise Edition transit router:

      • If an Enterprise Edition transit router is already created in the region where you want to create a VPC connection, configure the VpcId, ZoneMappings.N.VSwitchId, ZoneMappings.N.ZoneId, TransitRouterId, and RegionId parameters.
      • If no Enterprise Edition transit router is created in the region where you want to create a VPC connection, configure the VpcId, ZoneMappings.N.VSwitchId, ZoneMappings.N.ZoneId, CenId, and RegionId parameters. Then, the system automatically creates an Enterprise Edition transit router in the specified region.

    • CreateTransitRouterVpcAttachment 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 ListTransitRouterVpcAttachments operation to query the status of a VPC connection.

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

    • By default, route learning and associated forwarding are disabled between transit router route tables and VPC connections.

    Prerequisites

    Before you call this operation, make sure that the following requirements are met:

    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.
