There is no reason. HA can be connected via wired link to R, and R doesn't need the wireless link at all, just 2 wired interfaces. > What if R and HA are connected through a cross-over ethernet cable? > > How significant is this and how will it effect the tests and operation > of MIP? Doesn't matter at all. To simplify the test bed, you can have R and HA in the same box. Just make sure the routes match this too. A realistic scenario might be something like this: ISP--|R|--corporate network--|HA|--|AP|...|MN| You have some heavy duty wired router connected to internet (meaning ISP's network) and corporate network (I leave out firewalls and everything else for simplicity). If there are a lot of potential MNs, HA might be a dedicated server in the machine room with two wired interfaces, one connected to the corporate network and the other connected to a wireless access point (bridge). HA would advertise itself on the wireless link provided by AP, which would be the home link for the corporation's MNs. In a home environment you don't need all that and your network could look something like this: ISP--|HA|...|MN| Here the HA might be a combined ADSL router, wireless AP, and Home agent (and firewall etc.). You could run everything on e.g. OpenWRT supported box. Since in a home environment, there wouldn't be that many MNs, this would be sufficient. The point of all this is, that Mobile IPv6 may be configured the same in both cases. You would only have to change routes to match the topology.
