Hello Hiroki-san, The box I am using is FreeBSD 7.0-Release:

I tried this, and it add the expected route for the prefix: 2001:db8:1234:abcd::/64 link#1 UC em0 But when I pinged the router, I still got no success: # ping6 2001:db8:1234:abcd::fff2 PING6(56=40+8+8 bytes) 2001:db8:1234:abcd:20c:27ff:fe3d:63dd --> 2001:db8:1234:abcd::fff2 ping6: sendmsg: Invalid argument ping6: wrote 2001:db8:1234:abcd::fff2 16 chars, ret=-1 ping6: sendmsg: Invalid argument ping6: wrote 2001:db8:1234:abcd::fff2 16 chars, ret=-1 ^C --- 2001:db8:1234:abcd::fff2 ping6 statistics --- 2 packets transmitted, 0 packets received, 100.0% packet loss I also got this logged at the console: nd6_storelladdr: sdl_alen == 0 > > Your procedure looks correct to me and it should work on 7.0R, but on > both 7.1R and 7.2R it does not work at least.
