Introducing HP-UX Mobile IPv6

Returning Home and Deregistering

When a Mobile Node moves back to its home network, it determines whether it is attached to its home

network based on the network prefix information it receives in the Router Advertisements sent by Home

Agents on the home link. The Mobile Node deregisters by sending a special Binding Update to its Home

Agent to tell the Home Agent it is now attached to the home network. The Home Agent stops capturing and

forwarding data-packets for the Mobile Node. The Mobile Node sends a Neighbor Advertisement to link its

home address with its own link-level address.
