Last Updated:Mar 25, 2024

Deletes a multicast source from a multicast group.

Operation description

DeregisterTransitRouterMulticastGroupSources is an asynchronous operation. After a request a sent, the system returns a request ID and runs the task in the background. You can call the ListTransitRouterMulticastGroups operation to query the status of a multicast source.

  • If a multicast source is in the Deregistering state, the multicast source is being deleted. You can query the multicast source but cannot perform other operations.
  • If a multicast source cannot be found, the multicast source is deleted.

Before you call DeregisterTransitRouterMulticastGroupSources, make sure that all the request parameters are valid. If a request parameter is invalid, a request ID is returned but the multicast source is not deleted.


OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.
