--- Comment #6 from Andrey V. Elsukov <ae@FreeBSD.org> ---
You can use no_dad flag when you create vlan interface. We usually configure
all addresses manually on carp interfaces and also use -auto_linklocal flag:

# vlan416
carp_interfaces=3D"${carp_interfaces} vlan416"
ifconfig_vlan416=3D"vlan 416 vlandev ${vlanif} mtu 1500"
ifconfig_vlan416_ipv6=3D"inet6 -auto_linklocal no_dad"
ifconfig_vlan416_alias1=3D"inet A.B.C.D/28 vhid N ${carp_args}"
ifconfig_vlan416_alias2=3D"inet6 XX:XX:XX:XX::1/64 vhid M ${carp_args}"
ifconfig_vlan416_alias3=3D"inet6 fe80::1/64 vhid M ${carp_args}"
