Product Overview: HP-UX Mobile IPv6 A.01.00
The Transport Optional Upgrade Release (TOUR) 2.0, available free of charge at HP’s
Software depot, http://www.software.hp.com, delivers the first release of HP-UX Mobile
IPv6 software.
HP-UX Mobile IPv6 A.01.00 implements the Mobile IPv6 protocol, which uses and expands
several IPv6 protocol mechanisms. HP-UX Mobile IPv6 A.01.00 provides mobility support for
IPv6 on HP-UX 11i version 1 and version 2 servers.
NOTE HP-UX Mobile IPv6 is not Mobile Node client software.
With Mobile IPv6, Mobile Nodes such as laptops, PDAs, and cellular phones, remain
reachable and retain their network connections while moving and attaching to the network
from different locations. Each Mobile Node sends and receives IP data packets using a single,
fixed IPv6 address—known as its Home Address—for an extended period regardless of its
location.
Without Mobile IPv6, Mobile Nodes cannot use a single, fixed IPv6 address while they roam.
Instead, each time a Mobile Node moves and changes network attachment points, it must
manually re-configure a new IP address and default router based on its current
location—temporarily losing its network connections and ability to communicate in the
process.
The Mobile Node’s Home Address is an IPv6 unicast routable (global) address with a network
prefix on the Mobile Node’s Home Network. The Mobile Node’s Home Network is the network
that administers the Mobile Node, and the network to which the Mobile Node is normally
attached.
When a Mobile Node is attached to a Foreign Network—any network other than its Home
Network—it gets a temporary Care-of Address on the Foreign Network that identifies its
current point of attachment to the Internet. The Care-of Address is an IPv6 unicast global
address with the network prefix of the Foreign Network. The Mobile Node can get this
address using IPv6 stateless autoconfiguration, or by using a stateful configuration method
such as DHCP.
