Hi all,
[ Reposted from NetworkManager list as it's kinda quiet over there right now ]
Fedora 20 here. nm is 0.9.9.0-41.git20131003. (Old, I know)
Network Manager shows em1 "Wired" as being down. I have em1 configured as down.
Yet, I notice the following:
# ip -6 r
default via fe80::<redacted> dev wlp2s0 proto static metric 1024
default via fe80::<redacted> dev em1 proto ra metric 1024 expires 597sec
# ifconfig em1

Down means down, but only for IPv4.
I have noticed this for several months, and occasionally, it causes a problem with IPv6
connectivity.
Any pointers would be appreciated, before I disable IPv6 completely.
Well, when I look at the above and see "4163<UP,BROADCAST" I get the feeling
that NM isn't really marking the interface down.
If you were to issue "ip link set em1 down" it would truly be down. But, that
doesn't survive a reboot.
