IPv6 CARP with preempt not working

[Ivan R. Sy Jr.]

Hi All!

have anyone of you guys found a suitable solution/lead to this issue?

if you enable a CARP interface with ipv4 and ipv6 address it would work 
pretty neat.

carp0: flags=41<UP,RUNNING> mtu 1500
         inet 10.3.2.30 netmask 0xff000000
         inet6 2001:abc:4002::ff30 prefixlen 64
         carp: MASTER vhid 1 advbase 1 advskew 1


but with

net.inet.carp.preempt=1

IPv6 won't work. perhaps there are no inet6 sys controls?

any help or advise is highly appreciated.

THanks
