Problem with ipv6_activate_all_interfaces="YES"

I'm trying to get IPv6 running on a FreeBSD 11.0-RELEASE.

It works well with ipv6_enable="YES" in /etc/rc.conf.
But with ipv6_activate_all_interfaces="YES" it's not.

I'm stuck, please help. :)

My /etc/rc.conf:
Code: 
hostname="roflserver"

sshd_enable="YES"
ifconfig_vtnet0_name="vtnet0"

# Setup IPv6
ipv6_activate_all_interfaces="YES"
#ipv6_enable="YES"
ifconfig_vtnet0_ipv6="inet6 2a03:aaaa:bb:ccc::1 prefixlen 64"
#ifconfig_vtnet0_alias0="inet6 2a03:aaaa:bb:ccc::2 prefixlen 64"
ipv6_defaultrouter="fe80::1"

#Setup IPv4
ifconfig_vtnet0="inet 123.45.678.54 netmask 255.255.252.0"
defaultrouter="123.45.67.1"

# Set dumpdev to "AUTO" to enable crash dumps, "NO" to disable
dumpdev="NO"

#Setup the interface that all jails use
cloned_interfaces="lo1"
ifconfig_lo1="inet 172.16.1.1 netmask 255.255.255.0" #wwwjail
ifconfig_lo1_alias0="inet 172.16.1.2 netmask 255.255.255.255" #jabberjail
#ifconfig_lo1_alias1="inet 172.16.1.3 netmask 255.255.255.255" #bla

#pf_enable="YES"
ezjail_enable="YES"

Try without the ipv6_activate_all_interfaces="YES" variable:

From rc.conf(5):

Code: 
ipv6_activate_all_interfaces
                 (bool) This controls initial configuration on IPv6-capable
                 interfaces with no corresponding ifconfig_<interface>_ipv6
                 variable.  Note that it is not always necessary to set this
                 variable to ``YES'' to use IPv6 functionality on FreeBSD.  In
                 most cases, just configuring ifconfig_<interface>_ipv6
                 variables works.
 
Edit: Solved it.
The problem was this line:
ipv6_defaultrouter="fe80::1"
but it should be:
ipv6_defaultrouter="fe80::1%vtnet0" in my case.
 
And do not use ipv6_enable, it's deprecated as of FreeBSD 9.x.

From rc.conf(5):
ipv6_enable

(bool) This variable is deprecated. Use ifconfig_<interface>_ipv6 and ipv6_activate_all_interfaces if necessary.

If the variable is ``YES'', ``inet6 accept_rtadv'' is added to all of ifconfig_<interface>_ipv6 and the ipv6_activate_all_interfaces is defined as ``YES''.
