Hey guys!

 This problem still exists on Ubuntu Vivid!

 Come on! Ubuntu Desktop is near useless on a network with IPv6 + SLAAC
with Routers in H.A. When the main router dies, the slave router becomes
active (radvd) but, all Ubuntu Desktops (Gnome / Unity) doesn't see the
new IPv6 router. While Windows, Mac, Ubuntu Servers (without NM) and
Enlightenment DE with Econnman are working as expected.

 Please, fix this! Maybe it is time to bring Network Manager 1.0 to
Ubuntu.

 Right now, on my personal machine, I removed network-manager packages
and I'm configuring my IPv6 network directly on /etc/network/interfaces,
since NM is useless on an IPv6 + SLAAC network with routers in H.A..

 Also, my laptop have Econnman, from Enlightenment project. It works
like a charm! But it doesn't have support for proxy settings, then, I'm
stucked with manual config.    :-/

Thanks,
Thiago

Title:
  IPv6 static default route added incorrectly by network-manager

Status in NetworkManager:
  Fix Released
Status in network-manager package in Ubuntu:
  Confirmed

Bug description:
  The relevant part of the IPv6 routing table looks like this:

  fe80::/64 dev wlan0  proto kernel  metric 256
  default via fe80::5054:ff:fe64:aad0 dev wlan0  proto static  metric 1
  default via fe80::5054:ff:fe9c:741e dev wlan0  proto kernel  metric 1024  expires 8sec
  default via fe80::5054:ff:fe64:aad0 dev wlan0  proto kernel  metric 1024  expires 10sec

  I believe the proto static metric 1 route is an error, since it
  persists even when the router stops advertising.  This breaks the IPv6
  architecture for router redundancy.

  I am in control of this network and can alter router advertisement
  parameters if needed.
