Mobile IPv6 Frequently Asked Questions

24. What kernel parameters need to be configured? What parameters can be

configured?

The necessary configuration steps are documented in detail in the HP-UX Mobile IPv6

Administrator’s Guide located at

http://docs.hp.com/hpux/netcom/index.html/#HP-UX%20Mobile%20IPv6

25. Are there compatibility issues with the previous releases?

There are no compatibility issues with the previous releases, because this is the first

release of Mobile IPv6.

HP-UX IPSec version A.20 or later is required to protect signaling and payload traffic

with HP-UX Mobile IPv6. IPSec is not required for installation of Mobile IPv6.

26. Are there interoperability issues? Which products does it work with?

HP participated in TAHI and Connectahon conformance and interoperability testing

events using HP-UX Mobile IPv6 with other Mobile IPv6 vendors. There are no known

interoperability issues.

For more information on conformance testing, refer to the TAHI website at

http://www.tahi.org/.

27. What is the performance impact of this product on my system?

Mobile IP is a signaling protocol between the Mobile Node and the Home Agent or

Correspondent Node, used to track the location of Mobile Nodes. In a typical

deployment scenario, about 5 - 10% of the system bandwidth will be spent on MIPv6

signaling.

However, IPSec is required on the Home Agent to protect signaling traffic as well as

payload traffic. IPSec is very CPU intensive, and it is expected that there will be

some performance impact caused by IPSec. Refer to the IPSec documentation for

additional performance information..
