I tried the same configuration (with the different interface card)
using the latest RELENG-6 in my environment, but I couldn't reproduce
your problem.
So could you please show me the result of the following commands?
- netstat -rnf inet6
- ndp -i dc0
- ndp -na
- kernel log message after sysctl -w net.inet6.icmp6.nd6_debug=1
(if exists)

At least these two does not seem to be relating to this problem.
Thanks,
