To deploy an Avi Load Balancer Controller cluster, first deploy a single Avi Load Balancer Controller node (the leader), and then add the Follower nodes to the Leader.
Ensure that after using the setup wizard to install Avi Load Balancer on the Follower nodes, you do not make any other configuration changes on these nodes.
For more information about initial cluster deployment, see Deploying Cluster topic in this guide.
