Cluster IP Advertisement

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

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

Note:

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