+### Testing networking
+
+To verify that the new cluster is working properly, we can deploy a
+tiny test deployment and see if it is globally reachable:
+
+```
+apiVersion: apps/v1
+kind: Deployment
+metadata:
+  name: nginx-deployment
+spec:
+  selector:
+    matchLabels:
+      app: nginx
+  replicas: 2
+  template:
+    metadata:
+      labels:
+        app: nginx
+    spec:
+      containers:
+      - name: nginx
+        image: nginx:1.20.0-alpine
+        ports:
+        - containerPort: 80
+---
+apiVersion: v1
+kind: Service
+metadata:
+  name: nginx-service
+spec:
+  selector:
+    app: nginx
+  ports:
+    - protocol: TCP
+      port: 80
+```
+
+Using curl to access a sample service from the outside shows that
+networking is working:
+
+```
+% curl -v http://[2a0a:e5c0:0:aaaa::e3c9]
+*   Trying 2a0a:e5c0:0:aaaa::e3c9:80...
