>Description:
Using ipv6 tunel freemet6 from ports on any recent RELENG_6 system causes hundreds of nd6_lookup: failed to add route for a neighbor(2001:05c0:8fff:fffe::0d0), errno=17 messages a second.

The tunel is not started or it's started too early in boot process:

It might be also released to bind errors (although the proper dev entries do exist in chroot).
>How-To-Repeat:
Install freenet6 port and add it to /etc/rc.conf upon boot it will not start and when manually started, hundreds of above message about ndlookup will spam logs and dmesg.
