+The roadwarriors <b>carol</b> and <b>dave</b> set up a connection each to
+gateway <b>moon</b>. Both <b>carol</b> and <b>dave</b> request a <b>virtual
+IP</b> via IKEv2 configuration payload.
+<p/>
+The gateway <b>moon</b> uses <b>route-based forwarding</b> with an <b>XFRM
+interface</b>, with firewall rules to allow traffic to pass. The IKE daemon
+does not install routes for CHILD_SAs with outbound interface ID, so a static
+route is installed for the virtual IP subnet via XFRM interface.
+<p/>
+Both <b>carol</b> and <b>dave</b> ping the client <b>alice</b> behind the
+gateway <b>moon</b>. The source IP addresses of the two pings will be the
+virtual IPs <b>carol1</b> and <b>dave1</b>, respectively.
