+## Introduction
+
+_Service Topology_ enables a service to route traffic based upon the Node
+topology of the cluster. For example, a service can specify that traffic be
+preferentially routed to endpoints that are on the same Node as the client, or
+in the same availability zone.
+
+## Prerequisites
+
+The following prerequisites are needed in order to enable topology aware service
+routing:
+
+   * Kubernetes 1.17 or later
+   * {{< glossary_tooltip text="Kube-proxy" term_id="kube-proxy" >}} running in iptables mode or IPVS mode
+   * Enable [Endpoint Slices](/docs/concepts/services-networking/endpoint-slices/)
+
+## Enable Service Topology
+
+{{< feature-state for_k8s_version="v1.17" state="alpha" >}}
+
+To enable service topology, enable the `ServiceTopology` and `EndpointSlice` feature gate for all Kubernetes components:
+
+```
+--feature-gates="ServiceTopology=true,EndpointSlice=true"
+```
+
+
+## {{% heading "whatsnext" %}}

+* Read about the [Service Topology](/docs/concepts/services-networking/service-topology) concept
+* Read about [Endpoint Slices](/docs/concepts/services-networking/endpoint-slices)
+* Read [Connecting Applications with Services](/docs/concepts/services-networking/connect-applications-service/)
