Enable ENI Multicast for Transit Router Groups Across Regions - Cloud Enterprise Network - Alibaba Cloud - Cloud Enterprise Network

Calls the RegisterTransitRouterMulticastGroupMembers operation to create or add multicast members.

Operation description

Currently, Enterprise Edition transit routers support only elastic network interfaces (ENIs) as multicast members. You can call the RegisterTransitRouterMulticastGroupMembers operation to specify ENIs in the same region or cross-region ENIs as multicast members.

If you specify the NetworkInterfaceIds parameter, you want to specify ENIs in the current region as multicast members. Make sure that the vSwitch to which the ENI belongs is associated with the multicast domain. For more information, see AssociateTransitRouterMulticastDomain.
If you specify the PeerTransitRouterMulticastDomains parameter, you want to specify multicast members in a multicast group with the same multicast IP address in a different region as multicast members of your current multicast group. Make sure that you have created an inter-region connection. For more information, see CreateTransitRouterPeerAttachment.

For example, you have Multicast Domain 1 in the China (Hangzhou) region with Multicast Group 1, and Multicast Domain 2 in the China (Shanghai) region with Multicast Group 2. Multicast Group 1 and Multicast Group 2 have the same multicast IP address, and Multicast Group 2 in the China (Shanghai) region has Multicast Member 2. When you call the RegisterTransitRouterMulticastGroupMembers operation to create multicast members for Multicast Group 1 in the China (Hangzhou) region, if you set PeerTransitRouterMulticastDomains to the ID of Multicast Domain 2 in the China (Shanghai) region, Multicast Member 2 in Multicast Group 2 in the China (Shanghai) region also becomes a multicast member of Multicast Group 1 in the China (Hangzhou) region.
The RegisterTransitRouterMulticastGroupMembers operation is asynchronous. After you send a request, the system returns a RequestId but the multicast member is not completely created. The creation task continues to run in the background. You can call the ListTransitRouterMulticastGroups operation to query the status of the multicast member.
- If the multicast member is in the Registering state, the multicast member is being created. In this state, you can only query the multicast member but cannot perform other operations.
- If the multicast member is in the Registered state, the multicast member is created.

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 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 client token can contain only ASCII characters. Note If you do not specify this parameter, the system automatically uses the RequestId of the API request as the ClientToken. The RequestId may be different for each API request.	123e4567-e89b-12d3-a456-426655440000
TransitRouterMulticastDomainId	string	Yes	The ID of the multicast domain to which the multicast member belongs.	tr-mcast-domain-91wpg6wbhchjeq****
GroupIpAddress	string	Yes	The IP address of the multicast group to which the multicast member belongs. Valid values: 224.0.1.0 to 239.255.255.254. Important 224.0.0.0 to 224.0.0.127 are system reserved IP addresses and cannot be used as multicast group IP addresses. If the multicast group that you specify does not exist in the current multicast domain, the system automatically creates a new multicast group in the current multicast domain.	239.XX.XX.2
NetworkInterfaceIds	array	No	The list of elastic network interfaces (ENIs) IDs.
	string	No	The network interface controller (NIC) ID. You can associate multiple elastic network interfaces (ENIs) at a time. Make sure that the total number of network interface controllers (NICs) and cross-region multicast domains that you specify is less than or equal to 5.	eni-p0weuda3lszwzjly****
PeerTransitRouterMulticastDomains	array	No	The list of cross-region multicast domain IDs.
	string	No	The cross-region multicast domain ID. You can associate multiple cross-region multicast domains at a time. Make sure that the total number of network interface controllers (NICs) and cross-region multicast domains that you specify is less than or equal to 5.	tr-mcast-domain-5mjb5gjb6dgu98****
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 limits. If the request fails the dry run, an error message is returned. If the request passes the dry run, the `DryRunOperation` error code is returned. false (default): performs a dry run and sends the request. If the request passes the dry run, the multicast member is created.	false
VpcId	string	No	The instance ID of the VPC-connected instance to which the elastic network interfaces (ENIs) belongs. If the network interface controller (NIC) belongs to the same Alibaba Cloud account that you use to logon to call this operation, you do not need to set this parameter. If the network interface controller (NIC) belongs to a different Alibaba Cloud account from the one you use to logon, you must set this parameter.	vpc-wz9fusm6zq8uy7cfa****
