    Cloud Enterprise Network:CreateTransitRouterMulticastDomain

    Last Updated:Oct 22, 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.

    Debugging

    You can run this interface directly in OpenAPI Explorer, saving you the trouble of calculating signatures. After running successfully, OpenAPI Explorer can automatically generate SDK code samples.

    Authorization information

    The following table shows the authorization information corresponding to the API. The authorization information can be used in the Action policy element to grant a RAM user or RAM role the permissions to call this API operation. Description:

    • Operation: the value that you can use in the Action element to specify the operation on a resource.
    • Access level: the access level of each operation. The levels are read, write, and list.
    • Resource type: the type of the resource on which you can authorize the RAM user or the RAM role to perform the operation. Take note of the following items:
      • The required resource types are displayed in bold characters.
      • If the permissions cannot be granted at the resource level, All Resources is used in the Resource type column of the operation.
    • Condition Key: the condition key that is defined by the cloud service.
    • Associated operation: other operations that the RAM user or the RAM role must have permissions to perform to complete the operation. To complete the operation, the RAM user or the RAM role must have the permissions to perform the associated operations.
