Introducing HP-UX Mobile IPv6

Overview

The HP-UX Mobile IPv6 product delivers mobility support for HP-UX IPv6 by providing Home Agent and

Correspondent Node functionality for HP-UX 11i version 1 and 2 servers. HP-UX Mobile IPv6 is based on the

following IETF standards, which can be found at http://www.ietf.org:

• RFC # 3775: Mobility Support in IPv6

• RFC # 3776: Using IPsec to Protect Mobile IPv6 Signaling between Mobile Nodes and Home Agents

NOTE HP-UX Mobile IPv6 is HP-UX server software—it is not Mobile Node client software.

Features and Functionality

The following is a list of the features and functionality HP-UX Mobile IPv6 provides:

• Home Agent support for Mobile IPv6 Mobile Nodes moving throughout the Internet

• Correspondent Node support for communicating or corresponding with IPv6 Mobile Nodes

• Route Optimization support for improving data transmission rates between Mobile Nodes and

Correspondent Nodes by reducing the number of hops the data traverses (bypassing the Home Agent).

• Return Routability Procedure support for securing Route Optimization between Mobile Nodes and

Correspondent Nodes.

• Dynamic Home Agent Address Discovery support to allow Mobile Nodes to dynamically ﬁnd the

address of a Home Agent on its home network when it needs to register its Care-of Address while away

from home.

• Preﬁx Discovery support to allow Mobile Nodes to learn preﬁx information about its home network for

conﬁguring its home address while away from home.

• Multi-processor Scaling support to increase the number of Mobile IPv6 Kernel Module instances

processing mobility message headers on a system.

• Compatibility with HP-UX IPSec A.02.00 to secure the Mobile IPv6 messaging between the Home

Agent and Mobile Node. Monitor http://www.software.hp.com for HP-UX IPSec A.02.00 availability.

• Dynamic-conﬁguration support to change mobility settings without restarting the HP-UX Mobile IPv6

Kernel module.

• System Administrator Utilities to create conﬁguration ﬁles and to administer the Mobile IPv6

sub-system change mobility settings without restarting the Mobile IPv6 Kernel module.
