Hi W.Steffen,

I'm not sure.  I suggest trying to figure out exactly what it is
you're seeing in TCPDUMP, or debugging radvdump.

Do you get an autoconfigured IPv6 address?  If you're not, and you're
not seeing anything on radvdump, I would think that TCPDUMP is showing
incorrect info.

You *may* be seeing IPv6 solicitations, not advertisements, in
TCPDUMP, but that's just a guess.
