Cloud Enterprise Network:CreateTransitRouterMulticastDomain

Last Updated:Jul 19, 2024

Creates a multicast domain. A multicast domain is a multicast network in a region. Only resources in the same multicast domain can transmit and receive multicast packets.

Operation description

Before you call this operation, read the following rules:

  • Make sure that an Enterprise Edition transit router is deployed in the region where you want to create the multicast domain, and the multicast feature is enabled for the Enterprise Edition transit router. For more information, see CreateTransitRouter .

    If an Enterprise Edition transit router was created before you apply for multicast resources, the transit router does not support multicast. You can delete the transit router and create a new one. For more information about how to delete an Enterprise Edition transit router, see DeleteTransitRouter .

  • When you call CreateTransitRouterMulticastDomain, if you set CenId and RegionId, you do not need to set TransitRouterId. If you set TransitRouterId, you do not need to set CenId or RegionId.
