Not necessarily, AFAICS (if HAO-option is used). Depends on how strict
your requirement on mobility (in this context, requirement for
non-breaking connections if IP changes; depends a lot on how architecture
is designed) is.
Do you see any flaws in my reasoning (this wasn't commented on) -- I think
this should answer some questions..

Requirements for MIP v6 (fwd)
Am I right by saying:
- with Home Address, without BU: the route will be suboptimal, but
mobility (connections break if MN changes IP address) will still work.
- with Home Address, with BU: route will be optimal and mobility works.
- without Home Address, without BU: the route will be optimal and
mobility will not work
- without Home Address, with BU: route will be optimal but mobility will
not work.
That is,
if HAO
mobility
if BU
route optimization
fi
else
route optimization
fi
>From above, the only reason why HAO should be useful for a dummy node not
implementing BU is mobility (non-breaking connections). Is that scenario
relevant enough to justify non-authorized HAO usage?
