Thanks for the clarification. I mistook the loadbalancer use based on the CSE 4.0 context.
You are right. We don't have this feature covered in the CPI component and will need to add it. We plan to use the `loadBalancerIP` field to specify it.
Would you mind creating a ticket for this in bugzilla (using VMware support), or at least in the CLoud provider (https://github.com/vmware/cloud-provider-for-cloud-director)? Else please let us know and we will do it. You could add yourself as a customer there.
