### Prerequisites

* One or more k8s clusters with version 1.13 or above
* One or more k8s clusters with version 1.16 or above
* [Install istio control plane](https://istio.io/docs/setup/install/multicluster/gateways/#deploy-the-istio-control-plane-in-each-cluster) on each of these k8s clusters
* [Configure DNS redirect](https://istio.io/docs/setup/install/multicluster/gateways/#setup-dns) for entries ending in `global`
* Configure DNS for service entries (hosts) ending in `global`
1. Istio 1.8 and above - [Enable DNS proxy mode](https://istio.io/latest/docs/ops/configuration/traffic-management/dns-proxy/) OR [Redirect DNS](https://istio.io/v1.6/docs/setup/install/multicluster/gateways/#setup-dns)
2. Istio 1.6 and below - [Redirect DNS](https://istio.io/v1.6/docs/setup/install/multicluster/gateways/#setup-dns)
* Remove envoy cluster rewrite filter
Delete Istio's envoy filter for translating `global` to `svc.cluster.local` at istio-ingressgateway because we don't need that as Admiral generates Service Entries for cross cluster communication to just work!
