Hi Bernard and Nicholas,

Can you please clarify something for me?

Is it possible to learn a potential secondary SSID by
using one from the previous AP (as the only non-broadcast
SSID used)?

I know this isn't useful as a movement hint, but may be used
as a definitive non-movement hint, if it means that we can
use the same VLAN, as on the previous AP.

Considering the number of intra-subnet movements with
such a topology, this could be a boon to reduce L3
handovers or L3 message exchanges.

Indeed.

It helps to have a clear understanding of how things
work (and current proposals in 802 or WFA) so that
we don't keep re-debating issues though.

Thanks for your help in de-fogging.
