How to config HA for Istio multi cluster with shared control plane

As I read at , We can config HA for Istio control plane by replication istio control pod to multi cluster. But I cannot find any tutorial or blog which configured it ?
I try copy deploy, svc, sa, configmap, secret in istio-system namespace from primary cluster to remote cluster but I cannot start pilot.
I try use DNS to point to pilot, telemetry, policy, but I cannot install remote profile with value.remotePilotAddress == domain (it have to IP address)
Any advice is welcome. Thanks in advance
