Use AssociateTransitRouterMulticastDomain to associate a vSwitch with a multicast domain - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Associates a vSwitch in a virtual private cloud (VPC) with a multicast domain by calling the AssociateTransitRouterMulticastDomain operation so that resources in the VPC can communicate through multicast.

Operation description

A vSwitch can be associated with only one multicast domain. Make sure that the vSwitch to be associated is not already associated with another multicast domain. To disassociate a vSwitch from a multicast domain, see DisassociateTransitRouterMulticastDomain.
AssociateTransitRouterMulticastDomain is an asynchronous operation. After you send a request, the system returns a RequestId but the association between the vSwitch and the multicast domain is not yet complete. The association task continues to run in the background. You can call ListTransitRouterMulticastDomainAssociations to query the association status between the vSwitch and the multicast domain.
- If the association status is Associating, the association between the vSwitch and the multicast domain is being established. In this state, you can only query the vSwitch but cannot perform other operations.
- If the association status is Associated, the association between the vSwitch and the multicast domain is established.
The VPC to which the vSwitch belongs must be connected to an Enterprise Edition transit router. To create a VPC connection, see CreateTransitRouterVpcAttachment.

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.

Request parameters

Parameter	Type	Required	Description	Example
ClientToken	string	No	The client token that is used to ensure the idempotence of the request. You can use the client to generate the token, but you must make sure that the token is unique among different requests. The client token can contain only ASCII characters.	123e4567-e89b-12d3-a456-426655440000
TransitRouterMulticastDomainId	string	Yes	The ID of the multicast domain.	tr-mcast-domain-91wpg6wbhchjeq****
TransitRouterAttachmentId	string	Yes	The ID of the VPC connection.	tr-attach-g3kz2k3u76amsk****
VSwitchIds	array	Yes	The list of vSwitch IDs.
	string	Yes	The vSwitch ID. You can associate up to 5 vSwitches at a time, and a multicast domain supports up to 10 associated vSwitches.	vsw-p0wxk12u6okfkr8xy****
DryRun	boolean	No	Specifies whether to perform a dry run. Valid values: true: performs a dry run without associating the vSwitch with the multicast domain. The system checks the required parameters, request syntax, and business restrictions. If the request fails the dry run, an error message is returned. If the request passes the dry run, the error code `DryRunOperation` is returned. false (default): performs a dry run and sends the request. If the request passes the dry run, the vSwitch is associated with the multicast domain.	false
