Cloud Enterprise Network:DeregisterTransitRouterMulticastGroupSources

Last Updated:Aug 07, 2025

If a multicast source no longer needs to send multicast traffic, you can call the DeregisterTransitRouterMulticastGroupSources operation to remove the multicast source from the multicast group.

Operation description

DeregisterTransitRouterMulticastGroupSources is an asynchronous operation. After you send a request, the system returns a RequestId, but the multicast source is not deleted immediately. The system deletes the multicast source in the background. You can call ListTransitRouterMulticastGroups to query the status of the multicast source.

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

  • If you cannot find the multicast source in the multicast domain when you call ListTransitRouterMulticastGroups, the multicast source has been deleted.

Ensure that you specify correct parameter values when you call the DeregisterTransitRouterMulticastGroupSources operation. If you specify an incorrect parameter, the operation 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 support 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.

Parameter

Type

Required

Description

Example

ClientToken

string

No

The client token that is used to ensure the idempotence of the request.

Generate a token on your client. Make sure that the token is unique among different requests. The `ClientToken` parameter can contain only ASCII characters.

123e4567-e89b-12d3-a456-4266****

TransitRouterMulticastDomainId

string

Yes

The ID of the multicast domain that contains the multicast source.

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

GroupIpAddress

string

Yes

The IP address of the multicast group that contains the multicast source.

NetworkInterfaceIds

array

No

The list of multicast source IDs.

string

No

The ID of the multicast source.

You can delete a maximum of 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: Sends a check request without deleting the multicast source. The check includes required parameters, request format, and business limits. If the check fails, the corresponding error is returned. If the check passes, the DryRunOperation error code is returned.

  • false (default): Sends a normal request. After the request passes the check, the multicast source is deleted.

Error message

Description

400 InvalidTransitRouterMulticastDomainId.NotFound The specified TransitRouterMulticastDomainId is not found. The error message returned because the specified ID of the multicast domain (TransitRouterMulticastDomainId) on the transit router does not exist.
400 InvalidOperation.MulticastDomainStatus Operation is invalid, due to multicast domain not Active. The error message returned because the status of the specified multicast domain does not support this operation.
400 IncorrectStatus.MulticastGroup The status of MulticastGroup is incorrect. The error message returned because the status of the specified multicast group does not support this operation. Try again later.
400 DryRunOperation Request validation has been passed with DryRun flag set. The error message returned because the dry run request passed the precheck.
400 OperationUnsupported.NotAllowedDeleteIgmpv2Member You cannot delete a multicast source or multicast member of the igmpv2 type. You cannot delete a multicast source or member of the igmpv2 type.
400 InvalidParameter Invalid parameter. The error message returned because the parameter is set to an invalid value.
400 Unauthorized The AccessKeyId is unauthorized. The error message returned because you do not have the permissions to perform this operation.
