Hi Wanjing, As it's Juno, I assume you are using LBaaSv1. If that's the case, as Brandon pointed, there's no subnet-id switch in the neutron lb-member-create command. Having said that you still use the subnet-id in both the following commands: neutron lb-pool-create neutron lb-vip-create You should note that the subnet id in each of the above commands serve different purpose. In the case of lb-pool-create, the subnet-id is provided to make sure that only members belonging to the specified subnet-id could be added to the pool. However, the subnet id in the lb-vip-create command specifies the network range from which an ip is chosen to be assigned as a vip. Thus, you could use different subnets for both the above commands and as long as you have route between those two, the load balancing works. Thanks, Bharath.
