at the outset of the scenario is also directly connected to the 192.168.0.0/24 network
via an additional <b>eth1</b> interface. <b>alice</b> builds up a tunnel to gateway <b>sun</b>
in order to reach <b>bob</b> in the subnet behind. When the <b>eth1</b> interface
goes away, <b>alice</b> switches to <b>eth0</b> and signals the IP address change
