Use RevokeInstanceFromTransitRouter to revoke transit router permissions on a cross-account network instance - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Operation description

The RevokeInstanceFromTransitRouter operation only supports revoking the permission that allows a transit router to connect to cross-account virtual private cloud (VPC) instances, virtual border router (VBR) instances, IPsec connections, and Express Connect Router (ECR) instances.

To revoke the permission that allows a transit router to connect to a cross-account Cloud Connect Network (CCN) instance, call the RevokeInstanceFromCbn operation.

Before you begin

Before you call the RevokeInstanceFromTransitRouter operation, make sure that the connection between the transit router and the VPC-connected instance is deleted.

To delete the connection between an Enterprise Edition transit router and a VPC instance, see DeleteTransitRouterVpcAttachment.
To delete the connection between an Enterprise Edition transit router and a VBR instance, see DeleteTransitRouterVbrAttachment.
To delete the connection between an Enterprise Edition transit router and an IPsec connection, see DeleteTransitRouterVpnAttachment.
To delete the connection between an Enterprise Edition transit router and an ECR instance, see DeleteTransitRouterEcrAttachment.
To delete the connection between a Basic Edition transit router and a VPC-connected instance, see DetachCenChildInstance.

Test

RAM authorization

The table below describes the authorization required to call this API. You can define it in a Resource Access Management (RAM) policy. The table's columns are detailed below:

Action: The actions can be used in the Action element of RAM permission policy statements to grant permissions to perform the operation.
API: The API that you can call to perform the action.
Access level: The predefined level of access granted for each API. Valid values: create, list, get, update, and delete.
Resource type: The type of the resource that supports authorization to perform the action. It indicates if the action supports resource-level permission. The specified resource must be compatible with the action. Otherwise, the policy will be ineffective.
- For APIs with resource-level permissions, required resource types are marked with an asterisk (*). Specify the corresponding Alibaba Cloud Resource Name (ARN) in the Resource element of the policy.
- For APIs without resource-level permissions, it is shown as All Resources. Use an asterisk (*) in the Resource element of the policy.
Condition key: The condition keys defined by the service. The key allows for granular control, applying to either actions alone or actions associated with specific resources. In addition to service-specific condition keys, Alibaba Cloud provides a set of common condition keys applicable across all RAM-supported services.
Dependent action: The dependent actions required to run the action. To complete the action, the RAM user or the RAM role must have the permissions to perform all dependent actions.
