Re-advertise Aggregate Routes with RefreshTransitRouteTableAggregation - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Operation description

For aggregate routes that failed to be published or were partially published, you can call the RefreshTransitRouteTableAggregation operation to republish the aggregate route to Virtual Private Cloud (VPC) instances after you resolve the route issue.

If you resolve the problematic route in the following ways, the system automatically republishes the aggregate route without manual intervention:

Delete the association forwarding relationship
Disable the route synchronization feature
Delete the VPC route table
Delete the aggregate route

You can call the DescribeTransitRouteTableAggregationDetail operation to query the propagation status of an aggregate route.

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.
