I don't think it needs fixing, because one can configure it to do
various things, and it isn't run by default.  It would only cause
trouble if someone is running a router and misconfigures things, and so
far we havn't seen that reported...

But, if you wanted to spiff it up so that when there aren't any global
prefixes, it either doesn't send RAs or doesn't advertise the default
route, with an option to make it send RAs anyway, that seems ok,
although it feels like extra code and effort to solve a non-problem.


There's a larger issue lurking, which is automatically turning off the
RA and/or ripng local default route when a tunnel is down, even if the
prefix is statically assigned.   That's far more into routing daemon
implementation though.
