HP-UX IPSec and HP-UX Mobile IPv6
Introduction
Chapter 7202
Mobile Node’s current Care-of Address and its home address. The Home
Agent also forwards packets addressed to the Mobile Node’s home
address to the Mobile Node’s Care-of Address as needed.
Home Agents and Basic Operation
In Mobile IPv6 Basic Operation, the Correspondent Node sends
data-packets to the Mobile Node using the Mobile Node’s home address.
A Home Agent (HA), a node or router on the Mobile Node’s home
network, intercepts these data-packets and sends them through an
IPSec tunnel to the Mobile Node’s current Care-of Address, as shown in
Figure 7-1, “Mobile IPv6 Basic Operation: Correspondent Node to Mobile
Node.”
