When I'm using em0 with simple config: ifconfig_em0=3D"inet 192.168.134.2 netmask 255.255.255.0 mtu 9000" ifconfig_em0_ipv6=3D"inet6 accept_rtadv" everything works fine - em0 get IPv6 prefix from rtadvd of my router and "tspdump -n -i em0 icmp6" shows some traffic, like router and prefix announcements. So far so good. I want to use em1 (and don't use em0 at all), because 82579LM has some known bugs according to SuperMicro support and someties hangs whole syste= m. So, I change config to ifconfig_em1=3D"inet 192.168.134.2 netmask 255.255.255.0 mtu 9000" ifconfig_em1_ipv6=3D"inet6 accept_rtadv" connect em1 instead of em0 to the switch and reboot. And after that interface (em1) can not get IPv6 prefix, don't get global address (and shows only link-local one)and "tcpdump -n -i em1 icmp6" shows nothing at all! IPv4 works fine, though. What do I do wrong? Is it known issue of 82574L? I'm running 10-STABLE r311462. --=20 // Lev Serebryakov AKA Black Lion --7cBXNCGcc6249uUSx8mBLvafUtq8sGafB-- --OSQIEdTTTT9av1bFQMCCaJmchsQ79ETgb Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (MingW32) iQJ8BAEBCgBmBQJYdW3qXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXRGOTZEMUNBMEI1RjQzMThCNjc0QjMzMEFF QUIwM0M1OEJGREM0NzhGAAoJEOqwPFi/3EePTYsQAKXgwFax2jAIyW2KyfPMRU47 wV2jlqSyAbuPQEY5WuNWspalRpUF/JfFLmDrbOfJudgTAsw/jZhFf5r04tbafcv+ njcy5vST3xqToqmpZzcWMjAJ61z+XOEGYN/+DYsu+GjZjBi5lJptEVuv5HRYS0ZR E+ZPRrPoBT4nJ3XV0nZzBVb5/I0Gg3sDg7zaqUF4BBgHUDVWQlOZfFwbEosUgFbg XEnDI2EVXNBpX99ES3dd8oyU6VPmt5VORw8m8kTUtIaxV7j/TuFXZ37N4P6UJ+u5 KCN3WAIQbcHrpLREb6oJ+v9JwRu/eGOjMsxFXRHd1oZ1vXN/tUVzpIDx7HWcHGv7 sJALLQIZhCoLV5bey/o2bOt2TtMrJylbamN8xe8mCvkks7EYYRFCBZhSp21leIbp W0VztHvgnJ3thrGRV7i6/e6ACvcOltQN6C0J0fm3NoD4fWhzlt6m5tUCR1cpqo4v a8IXO4VMMX+/CDFZWPYGrrZ8LeZIFkjDfIdA3NEUXoTi8XnVOEsvAY2DDNGRHwBh Cw1zEYhV80yYDyDujiCcnDz2/ff2ABLGLRZ9uyla1DPHGOfRVGCilWXeHk8WWtiC 8OYXcaMSYLodiBSDzj9C6S4ESQgfQdzNKHHSGv1CfLzNdikpnqtpHiCWWq0TtpG1 IUo4Sx9l6o+waj6WZ/Vn =ZW0l -----END PGP SIGNATURE----- --OSQIEdTTTT9av1bFQMCCaJmchsQ79ETgb--
