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.

Request parameters

Parameter	Type	Required	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 ClientToken parameter supports only ASCII characters.	123e4567-e89b-12d3-a456-4266****
TransitRouterMulticastDomainId	string	Yes	The ID of the multicast domain.	tr-mcast-domain-40cwj0rgzgdtam****
TransitRouterMulticastDomainName	string	No	The new name of the multicast domain. The name can be empty or 1 to 128 characters in length, and cannot start with http:// or https://.	nametest
TransitRouterMulticastDomainDescription	string	No	The new description of the multicast domain. The description can be empty or 1 to 256 characters in length, and cannot start with http:// or https://.	desctest
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 business restrictions. If the check fails, the corresponding error is returned. If the check succeeds, the `DryRunOperation` error code is returned. false (default): performs a dry run and sends the request. After the request passes the dry run, the name and description of the multicast domain are modified.	false
Options	object	No	The feature options of the multicast domain.
Igmpv2Support	string	No	Specifies whether to enable the IGMP feature for the multicast domain. After this feature is enabled, hosts can dynamically join or leave multicast groups by using Internet Group Management Protocol (IGMP). Valid values: enable. Note The IGMP feature is in public preview. To use this feature, contact your account manager to request access. The IGMP feature cannot be disabled after it is enabled.	enable
StrictSourceControl	string	No	Specifies whether to enable the strict multicast source control feature. If this feature is disabled, all ECS instances in the associated vSwitch can serve as multicast sources. If this feature is enabled, only ENIs that are statically configured or have sent IGMP Join messages can serve as multicast sources. Valid values: `enable`: enables the strict multicast source control feature. `disable`: disables the strict multicast source control feature. Note The strict multicast source control feature takes effect only for multicast domains with the IGMP feature enabled. Only one multicast domain with the strict multicast source control feature disabled can be created under a transit router.	enable
