https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D214746 --- Comment #2 from Athanasios Douitsis <aduitsis@douitsis.com> --- (In reply to Kubilay Kocak from comment #1) Running FreeBSD 10.3-RELEASE-p11 #0: Mon Oct 24 18:49:24 UTC 2016 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64 on b= oth nodes. This works (dead:beef instead of my real prefix): ifconfig_vmx0_ipv6=3D"inet6 accept_rtadv dead:beef::60/64" ifconfig_vmx0_alias1=3D"inet6 dead:beef::95/64 no_dad vhid 34 pass bar=E2= =80=9D dead:beef::60 is node0 and dead:beef::61 is node1. Both have dead:beef::95/= 64 as the common carp IPv6 address. Vhid 34 is randomly chosen.=20 For IPv4, I'm using a different vhid and pass, just to be on the safe side. Removing the no_dad from ifconfig_vmx0_alias1 and rebooting the BACKUP node causes the problem to appear. Backup node will compain about DAD upon reboo= t, ifconfig will say dead:beef::95/64 duplicated, so it can't really be used.= =20 Afterwards, trying to manualy issue=20 ifconfig inet6 dead:beef::95/64 vhid 34 pass bar will fail the first time, second time it will go through. --=20 You are receiving this mail because: You are the assignee for the bug.=
