I need to repeat: in sysctl.d put this line in a file, then reboot, then your test setup will show the failure:
net.ipv6.conf.all.autoconf = 0 Otherwise, in your test setup the tables are populated, then you delete the addresses, but the L3/4 code engaged by even a little time with the fe80:... address at least until there is a timeout in the tables (longer than you wait for your test) kills the platform. Putting the above in then rebooting will avoid that, so you will see the bug when at no time was there an fe80 address on the interface. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1959702 Title: Regression: ip6 ndp broken, host bridge doesn't add vlan guest entry to mdb To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1959702/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
