							- The roadwarrior <b>alice</b> is sitting behind the router <b>moon</b> but
 
- at the outset of the scenariou 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 
 
- via a MOBIKE ADDRESS_UPDATE notification to peer <b>sun</b>. Since <b>alice</b> has
 
- not configured a virtual IP address the IPsec policies must be updated.
