The NSX Advanced Load Balancer Controller cluster IP is ARPed by whichever NSX Advanced Load Balancer Controller is the primary (or leader, depending on the infrastructure type) within the cluster. When another NSX Advanced Load Balancer Controller becomes the primary, it will send out a gratuitous ARP to claim ownership of the cluster IP.

Administrators may manage any of the NSX Advanced Load Balancer Controllers within the cluster by directly accessing the cluster IP address. The NSX Advanced Load Balancer Controllers will handle all replication, so there is no requirement to make changes specifically on the primary NSX Advanced Load Balancer Controller.

Note:

In NSX Advanced Load Balancer, the cluster IP is not referred to as floating IP. In NSX Advanced Load Balancer, the term floating IP applies only to OpenStack.
