Subject:   IPv6 rtadv on FreeBSD 8.1?
Message-ID:  <878w4svp18.fsf@cjlinux.localnet>

next in thread | raw e-mail | index | archive | help
I have running versions of 7.3 and 8.0, so I tried experimenting with
8.1 in VirtualBox, but I ran into a couple of problems.  I have an 8.0
system that is running a IPv6 tunnel to sixxs.net, and it is running
rtadvd to act as the gatway for my network.  On the 8.1 system I
enabled IPv6 in rc.conf, but it is not picking up the advertised
address.  I can add it manually, and have put it in rc.local for now,
but it seems it should work automatically as my others do.  I noticed
that the ifconfig output shows a new line that is not in 8.0:
        nd6 options=3<PERFORMNUD,ACCEPT_RTADV>

Is there something that has changed in 8.1 that I have to enable, or
is there a problem with 8.1?  IPv6 is working to the extent that it
did assign a link-local address, and I can use that address as long as
I specify the interface.  My configuration is the same, and I didn't
have to enable anything on the others to get the global address
assigned automatically.

Thanks for any advice.
