Three more questions: 1. output of "ifconfig lagg0", "ifconfig bce0", and "ifconfig bce1". 2. output of "netstat -s -i". 3. output of "ndp -p". The cause of the message is that the automatically-configured address is not recognized as "configured" one and FreeBSD IPv6 stack is trying to add it every time a Router Advertisement message is received. I am still not sure why it happened, but the above three would help for further investigation. -- Hiroki ----Security_Multipart(Fri_Jun_20_13_08_12_2014_519)-- Content-Type: application/pgp-signature Content-Transfer-Encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iEYEABECAAYFAlOjs6wACgkQTyzT2CeTzy1PCgCgu0ik8r+qWFPcYnPimpgFCsk3 Y1oAnRn0prWi32YIc+uR3y2QLOy3sguJ =nnzI -----END PGP SIGNATURE----- ----Security_Multipart(Fri_Jun_20_13_08_12_2014_519)----
