Good day!

I have a strange behavior with 11-STABLE:
uname -a
11.0-STABLE FreeBSD 11.0-STABLE #0 r313042: Wed Feb 1 23:27:02 +05 2017 amd64
/etc/rc.conf
Code: 
# Local network
ifconfig_re0="inet 192.168.17.1  netmask 255.255.255.0"
ifconfig_re0_alias0="inet 192.168.18.1 netmask 255.255.255.0"

# Jail network aliases
ifconfig_lo0_alias0="inet 10.12.10.1/32"
ifconfig_lo0_alias1="inet 10.12.10.2/32"
ifconfig_lo0_alias2="inet 10.12.10.3/32"

# Internet
ifconfig_re1="inet a.b.c.d/28"
defaultrouter="a.b.c.1"
After booting server I have such situation:
Code: 
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=8209b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,WOL_MAGIC,LINKSTATE>

        nd6 options=21<PERFORMNUD,AUTO_LINKLOCAL>
        groups: lo
????

And I manually remove aliases from re1 and after that all seems fine (aliases exists only on lo0).

What can cause that mystical error?
 
Don't add those aliases to lo0, instead create a cloned interface lo1 and attach the addresses to that.
