Cloud Enterprise Network:DeregisterTransitRouterMulticastGroupSources

Last Updated:Aug 12, 2026

Removes a multicast source from a multicast group if you no longer need the multicast source to send multicast traffic.

Operation description

DeregisterTransitRouterMulticastGroupSources is an asynchronous operation. After you call this operation, the system returns a RequestId but the multicast source is not immediately deleted. The deletion task continues to run in the background. You can call the ListTransitRouterMulticastGroups operation to query the status of the multicast source.

  • If the multicast source is in the Deregistering state, the multicast source is being deleted. In this state, you can only query the multicast source but cannot perform other operations on it.

  • If the ListTransitRouterMulticastGroups operation cannot find the multicast source in the multicast domain, the multicast source has been deleted.

When you call the DeregisterTransitRouterMulticastGroupSources operation, make sure that the parameter values you specify are correct. If you specify incorrect parameter values, the system still returns a RequestId but does not delete the multicast source.

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.

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-a456-4266****

TransitRouterMulticastDomainId

string

Yes

The ID of the multicast domain to which the multicast source belongs.

tr-mcast-domain-91wpg6wbhchjeq****

GroupIpAddress

string

Yes

The IP address of the multicast group to which the multicast source belongs.

239.XX.XX.2

NetworkInterfaceIds

array

No

The IDs of the multicast sources.

string

No

The ID of the multicast source.

You can remove up to five multicast sources from a multicast group at a time.

Note

This parameter is required.

DryRun

boolean

No

Specifies whether to perform a dry run. Valid values:

  • true: performs a dry run. The system checks the required parameters, request syntax, and limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the DryRunOperation error code is returned.

  • false (default): performs a dry run and sends the request. If the request passes the dry run, the multicast source is deleted.
