Abstract
Mobile IPv6 uses IPsec to protect signaling between the home agent
and the mobile node. Mobile IPv6 base document defines the main
requirements these nodes must follow. This document discusses these
requirements in more depth, illustrates the used packet formats,
describes suitable configuration procedures, and shows how
implementations can process the packets in the right order.
