I too am seeing this bug but with a slightly different use-case. If a
user swaps out their default router, no IPv6 traffic will pass because
of the static route installed. I have to disconnect the interface in
Ubuntu and then reconnect to clear the static. At that point, the new
default-route learnt via RA's takes over.

It would be really great to get this one fixed. As IPv6 deployment
starts to ramp up it is going to affect more and more people.

Thanks, Nick

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.
