+= Creating a route using the default certificate through an Ingress object
+
+If you create an Ingress object without specifying any TLS configuration, {product-title} generates an insecure route. To create an Ingress object that generates a secure, edge-terminated route using the default ingress certificate, you can specify an empty TLS configuration as follows.
+
+.Prerequisites
+
+* You have a service that you want to expose.
+* You have access to the OpenShift CLI (`oc`).
+
+.Procedure
+
+. Create a YAML file for the Ingress object.  In this example, the file is called `example-ingress.yaml`:
++
+.YAML definition of an Ingress object
+[source,yaml]
+----
+apiVersion: networking.k8s.io/v1
+kind: Ingress
+metadata:
+  name: frontend
+  ...
+spec:
+  rules:
+    ...
+  tls:
+  - {} <1>
+----
++
+<1> Use this exact syntax to specify TLS without specifying a custom certificate.
+
+. Create the Ingress object by running the following command:
++
+[source,terminal]
+----
+$ oc create -f example-ingress.yaml
+----
+
+.Verification
+* Verify that {product-title} has created the expected route for the Ingress object by running the following command:
++
+[source,terminal]
+----
+$ oc get routes -o yaml
+----
++
+.Example output
+[source,yaml]
+----
+apiVersion: v1
+items:
+- apiVersion: route.openshift.io/v1
+  kind: Route
+  metadata:
+    name: frontend-j9sdd <1>
+    ...
+  spec:
+  ...
+    tls: <2>
+      insecureEdgeTerminationPolicy: Redirect
+      termination: edge <3>
+  ...
+----
+<1> The name of the route includes the name of the Ingress object followed by a random suffix.
+<2> In order to use the default certificate, the route should not specify `spec.certificate`.
+<3> The route should specify the `edge` termination policy.
