One can think of a scenario in which a Mobile Node is roaming only between foreign networks, never arriving home.

For offering this kind of service one needs a HA connected to the public IPv6 infrastructure. The MN’s home address has to have the same prefix as the HA’s one.

The Fokus testbed offers this kind of use of MIPv6 Home Agents for functionality and interoperability tests.

The Fokus testbed offers this kind of use of MIPv6 Home Agents for functionality and interoperability tests.

The required configuration parameters for the concerning MN are:

In case you want to use the Linux HA: MIPL HA-address: mipl.lab6.fokus.fraunhofer.de (2001:638:806:2002:201:2ff:feb8:257f) Home address in the network: 2001:638:806:2002::/64

In case you want to use the Kame HA: KAME HA-address: kame.lab6.fokus.fraunhofer.de (2001:638:806:2001:250:daff:fe13:227b) Home address in the network: 2001:638:806:2001::/64 (Note: To use the Kame HA with a Linux Mobile Node (MN) you need at least version 1.1 of the MIPL-implementation.)

In order to support simple MN-CN connectivity/roaming tests an IPv6 H.323-MCU was connected to the “2001”-network: The address of the MCU is: mcu.lab6.fokus.fraunhofer.de (2001:638:806:2001:20e:a6ff:feb3:54a5) There are two conferencing rooms, the default room is "room101". For the convenience of checking local audio settings an audioloopback room called "loopback" was set up. If you encounter any kind of audio problems in "room101", please use the room "loopback" first to check if your local microphone and speaker settings work correctly.

There is no security association or any other restriction whatsoever. Any Mobile Node in the network above should be able to use these HAs.
