Yes, I'm pretty sure it is a Fritz "weirdness" (or just plain bug).
Catching it in the act isn't going to be so simple since I don't know
what triggers it.

Also: this looks like it's assigning a prefix to my second interface, as
asked (as in the example from the manual). But does it add a route for
it? NetBSD 7.0's dhcpcd-run-hooks doesn't know about DELEGATED6 so it
isn't done there.

But when I do a "route get" for some host on that interface, I get the
default route, i.e. not to re0.  Looking at it from the local network,
pings don't get replies.  I tried it a few hours after re0 was initially
set up, so something could have timed out in the mean time.

It's all so annoying... I had a perfectly working static setup with a
tunnel for IPv6 but now that I'm forced to use the FritzBox and its
dynamic stuff, my whole network is broken. </whine>
