I think it's still used a bit ? I see today announcements over the
following OriginAS over more than 2000 peers.

Announced and used are two different things.. :)

I'm pretty sure that 2002: address is (a) *your* end of the tunnel and
(b)
only visible inside your network and *inside* the HE tunnel to the other
end.
In other words, it shouldn't be seen out on the public net if it's
transiting
an HE tunnel. I bet if you changed that '-i any' to '-i wlan' (for
whatever
your router calls the outbound-facing interface) you won't see traffic
on 2002:
You're right, it does need to be public to work ;) So my question is why
it is still and it was announced on DFZ ?
