Cloud Enterprise Network:RegisterTransitRouterMulticastGroupMembers

最終更新日:Jun 19, 2025

Creates or adds a multicast member.

Operation description

Enterprise Edition transit routers support only elastic network interfaces (ENIs) as multicast members. You can call the RegisterTransitRouterMulticastGroupMembers operation to specify an ENI in the current region or a different region as a multicast member.

  • If you specify a value for the NetworkInterfaceIds parameter, an ENI in the current region is to be specified as a multicast member. Make sure that the ENI and vSwitch are associated with the multicast group. For more information, see AssociateTransitRouterMulticastDomain.

  • If you specify a value for the PeerTransitRouterMulticastDomains, a multicast member in a multicast group that belongs to another region but has the same IP address as the current multicast group is to be specified as a multicast member for the current multicast group. Make sure that an inter-region connection is established between the regions. For more information, see CreateTransitRouterPeerAttachment.

    For example, you created Multicast Group 1 in Multicast Domain 1, which is in the China (Hangzhou) region. You created Multicast Group 2 in Multicast Domain 2, which is in the China (Shanghai) region. Multicast Group 1 and Multicast Group 2 use the same multicast IP address, and Multicast Member 2 is in Multicast Group 2 in the China (Shanghai) region. If you call the RegisterTransitRouterMulticastGroupMembers operation to add multicast members to Multicast Group 1 in the China (Hangzhou) region and set PeerTransitRouterMulticastDomains to the ID of Multicast Group 2, which is in the China (Shanghai) region, Multicast Member 2, which is in Multicast Domain 2 in the China (Shanghai) region is added to Multicast Group 1 in the China (Hangzhou) region.

  • RegisterTransitRouterMulticastGroupMembers is an asynchronous operation. After a request is 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 member.

    • If the multicast member is in the Registering, the multicast member is being created. In this case, you can query the multicast member but cannot perform other operations on the multicast member.

    • If the multicast member is in the Registered state, the multicast member is created.

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 token can contain only ASCII characters.

Note

If you do not specify this parameter, the system automatically uses the request ID as the client token. The request ID may be different for each request.

TransitRouterMulticastDomainId

string

Yes

The ID of the multicast domain to which the multicast members belong.

tr-mcast-domain-91wpg6wbhchjeq****

GroupIpAddress

string

Yes

The IP address of the multicast group to which the multicast members belong. Valid values: 224.0.0.1 to 239.255.255.254.

If the multicast group does not exist in the specified multicast domain, the system automatically creates the multicast group in the multicast domain.

239.XX.XX.2

NetworkInterfaceIds

array

No

The IDs of the ENIs.

string

No

The ID of the ENI

You can specify multiple ENIs in each call. Make sure that the sum of the number of ENIs and the number of inter-region multicast domains is not larger than five.

eni-p0weuda3lszwzjly****

PeerTransitRouterMulticastDomains

array

No

The IDs of inter-region multicast domains.

string

No

The ID of the inter-region multicast domain.

You can specify multiple inter-region multicast domains in each call. Make sure that the sum of the number of ENIs and the number of inter-region multicast domains is not larger than five.

tr-mcast-domain-5mjb5gjb6dgu98****

DryRun

boolean

No

Specifies whether to perform a dry run, without performing the actual request. Valid values:

  • true: performs only a dry run. The system checks the request for potential issues, including missing parameter values, incorrect request syntax, and service limits. If the request fails the dry run, an error code is returned. If the request passes the dry run, the DryRunOperation error code is returned.

  • false (default): performs a dry run and performs the request.

false

VpcId

string

No

The ID of the VPC to which the ENI belongs.

  • If the ENI belongs to the current Alibaba Cloud account, ignore this parameter.

  • If the ENI belongs to a different Alibaba Cloud account, you must set this parameter.
