I've obtained a point-to-point tunnel from freenet6.net, built "tspc",
and it mostly works fine.

fredb@tautology-> ifconfig gif0
gif0: flags=8011<UP,POINTOPOINT,MULTICAST> mtu 1280
        tunnel inet 209.100.230.146 --> 206.123.31.114
        inet6 fe80::2a0:ccff:fe54:1bb4%gif0 -> :: prefixlen 64 scopeid 0x10
        inet6 3ffe:b80:2:33b::2 -> 3ffe:b80:2:33b::1 prefixlen 64

The kernel message buffer and syslogd are overrun with this, though:

nd6_lookup: failed to add route for a neighbor(3ffe:0b80:0002:033b::0001), errno=17
nd6_lookup: failed to add route for a neighbor(3ffe:0b80:0002:033b::0001), errno=17
nd6_lookup: failed to add route for a neighbor(3ffe:0b80:0002:033b::0001), errno=17
nd6_lookup: failed to add route for a neighbor(3ffe:0b80:0002:033b::0001), errno=17

or

Aug 14 01:10:42 tautology /netbsd: nd6_lookup: failed to add route for a neighbor(3ffe:0b80:0002:033b::0001), errno=17
Aug 14 01:10:59 tautology last message repeated 54 times

but only when ipv6 is active. The last indicates it hits about 3 times
per second. Any idea what that means?
