--- Comment #7 from Zhenlei Huang <zlei.huang@gmail.com> ---
It looks like the upstream router's neighbor cache entry expired and then it
issued Neighbor Solicitation messages but the host ignored them.

Can you please confirm that there're no firewall rules on your FreeBSD host
blocking the NS messages? You can disable IPFW / PF / IPF and reboot to get a
clean environment.

Check PF:
# pfctl -s Running

For IPFW:
# ipfw show

And also check statistics for ICMP6:
# netstat -sp icmp6
