https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D233683 --- Comment #16 from Kristof Provost <kp@freebsd.org> --- (In reply to Andrey V. Elsukov from comment #15) It's not hardware related. I can trivially reproduce the issue on if_epair. There's long debugging saga in https://redmine.pfsense.org/issues/13423, but here's a short version: > [kp@nut ~]$ sudo ifconfig epair create epair0a > [kp@nut ~]$ sudo ifconfig epair0a inet6 2001:db8::1/64 up > [kp@nut ~]$ ifmcstat -i epair0a > epair0a: > inet6 fe80::9e:e8ff:fe02:780a%epair0a scopeid 0xc > mldv2 flags=3D2<USEALLOW> rv 2 qi 125 qri 10 uri 3 > group ff02::1:ff00:1%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:ff:00:00:01 > group ff01::1%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:00:00:00:01 > group ff02::2:6c69:386f%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:6c:69:38:6f > group ff02::2:ff6c:6938%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:ff:6c:69:38 > group ff02::1%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:00:00:00:01 > group ff02::1:ff02:780a%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:ff:02:78:0a > [kp@nut ~]$ sudo ifconfig epair0a inet6 2001:db8::1/64 > [kp@nut ~]$ ifmcstat -i epair0a > epair0a: > inet6 fe80::9e:e8ff:fe02:780a%epair0a scopeid 0xc > mldv2 flags=3D2<USEALLOW> rv 2 qi 125 qri 10 uri 3 > group ff01::1%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:00:00:00:01 > group ff02::2:6c69:386f%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:6c:69:38:6f > group ff02::2:ff6c:6938%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:ff:6c:69:38 > group ff02::1%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:00:00:00:01 > group ff02::1:ff02:780a%epair0a scopeid 0xc mode exclude > mcast-macaddr 33:33:ff:02:78:0a Note the lost subscription to the ff02::1:ff00:1%epair0a group. --=20 You are receiving this mail because: You are the assignee for the bug.=
