testing: Reorganizing IKEv1 and IKEv2 examples
For documentation purposes the new folders ikev1-algs, ikev2-algs, ikev1-multi-ca and ikev2-multi-ca have been created. Most of the test cases have now been converted to the vici interface. The remaining legacy stroke scenarios yet to be converted have been put into the ikev2-stroke-bye folder. For documentation purposes some legacy stroke scenarios will be kept in the ikev1-stroke, ikev2-stroke and ipv6-stroke folders.

The roadwarrior <b>alice</b> is sitting behind the NAT router <b>moon</b> but
|
||||
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
|
||||
via a MOBIKE ADDRESS_UPDATE notification to peer <b>sun</b>. <b>alice</b> sets
|
||||
a virtual IP of 10.3.0.3, so that the IPsec policies don't have to be changed.
