+= Configuring the route admission policy
+
+By default, {microshift-short} allows routes in multiple namespaces to use the same hostname. You can prevent routes from claiming the same hostname in different namespaces by configuring the route admission policy.
+
+.Prerequisites
+
+* You installed {microshift-short}.
+* You created a {microshift-short} `config.yaml` file.
+* You installed the {oc-first}.
++
+[TIP]
+====
+If you complete all the configurations that you need to make in the {microshift-short} `config.yaml` file at the same time, you can minimize system restarts.
+====
+
+.Procedure
+
+. To prevent routes in different namespaces from claiming the same hostname, update the `namespaceOwnership` field value to `Strict` in the {microshift-short} `config.yaml` file. See the following example:
++
+.Example `config.yaml` route admission policy
+[source,yaml]
+----
+# ...
+ingress:
+  routeAdmissionPolicy:
+    namespaceOwnership: Strict <1>
+# ...
+----
+<1> Prevents routes in different namespaces from claiming the same host. Valid values are `Strict` and `InterNamespaceAllowed`. If you delete the value in a customized `config.yaml`, the `InterNamespaceAllowed` value is set automatically.
+. To apply the configuration, restart the {microshift-short} service by running the following command:
++
+[source,terminal]
+----
+$ sudo systemctl restart microshift
