The Avi Load Balancer Controller cluster IP address is a single IP address shared by multiple Controllers within a cluster. It is the address to which the web interface, CLI commands, and REST API calls are directed. As a best practice, to access the Controller, you must log in to the cluster IP address instead of the IP addresses of individual Controller nodes.
For cluster IPs, the management IPs of the Controllers must all be in the same subnet.
You can use Route 53 with health checks to resolve the cluster's domain name to a Controller IP address directly in AWS deployments where Controllers are on different subnets. For complete information on cluster configuration in AWS, see NSX Advanced Load Balancer Controller Cluster Configuration in AWS.
