--- Comment #2 from Marie Helene Kvello-Aune <marieheleneka@gmail.com> ---
on 11-current (r295762), steps to reproduce:
# ifconfig igb1 inet 10.0.1.1/24
# route add -net 10.0.2.0/24 10.0.1.2
# netstat -rn
(...)
10.0.2.0/24        10.0.1.2           UGS        igb1
(...)

# ifconfig igb1 inet 10.0.1.13/24
# netstat -rn
-- the 10.0.2.0/24 route is gone --

Reading about possible causes in the linked thread, I've checked dmesg and =
the
interface isn't down/up'ed when changing IP.
