No

String

Specifies the ID of the IPv4 subnet where the load balancer works. You can query neutron_subnet_id in the response by calling the API (GET https://{VPC_Endpoint}/v1/{project_id}/subnets).

  • The IPv4 subnet can be updated using vip_subnet_cidr_id, and the private IPv4 address of the load balancer will be changed accordingly.

  • If vip_address is also specified, the IP address specified by it must be in the subnet specified by vip_subnet_cidr_id and will be used as the private IPv4 address of the load balancer.

  • The IPv4 subnet must be in the VPC specified by vpc_id.

Note:

  • vip_subnet_cidr_id can be updated only when guaranteed is set to true.

  • Enter null if the private IPv4 address is unbound from the load balancer.
