Wouldn't it be possible to send out Router Solicitations on the dial-up
interface on initialization and with (long) interval?
By doing this, the connection is open, so the ISP is able to return a Router
Advertisement packet...

Subject: Stateless autoconf and dial-on-demand
Hi
I have a question regarding IPv6 stateless address
autoconfiguration in
combination with dial-on-demand network access.
Suppose I have a network configured using only stateless
address
autoconfiguration. At this point all hosts have a link local
address but
nothing with wider scope. When a connection to the outside
world is opened
the gateway node starts to receive router advertisements
from our ISP with
a globally routable prefix. This prefix is distributed to
the hosts on the
local network so that they can form complete, global IP
addresses.
How does one implement dial-on-demand in such a setting? The
gateway for
the network needs an outbound packet to trigger the dialing
process, but at
that time the emitting host does not have a global address
to select as the
packet source address. Hence the packet cannot be sent.
Is there any way to avoid having to rewrite the first
outbound packets in
the gateway? If it is not acceptable to open the connection
when no traffic
is being sent and if we cannot assume that everybody uses
DNS I don't
really see how it could be done.
Best regards
Morten Heiberg
