I'm trying to implement RA failover at my site, but NetworkManager grabs
first RA it sees to set a (static) default route with metric 1, and then it
sits there even when the lifetime of this route has expired (and no more
from that host). Is this a bug or some feature tham I'm overlooking.

Which version of NetworkManager do you have?  I  know there were some
lifetime issues with previous versions of NM, but it would certainly be
a bug if NetworkManager continued to leave a default route up when the
router's lifetime had expired.

The metric one suggest it's a pre-libndp version. At that time the route management was rather difficult.

Time to switch to fc20 now, will be back when this is done.
Ok, when running NetworkManager- default route changes
when the lifetime of a (dead) route has expired. Unfortunately that doesn't help much
since old routes to specific hosts seems to be stuck in the kernel (at least when using ping6), 
like this:

  2a00:1450:4005:808::1011 via fe80::64:1ff:fe00:2 dev eth0  proto static  metric 1 
  2a00:1450:4005:808::1013 via fe80::13:10ff:fe07:1158 dev eth0  proto static  metric 1 
  2a00:1450:4005:808::1014 via fe80::13:12ff:fe10:1311 dev eth0  proto static  metric 1 
  default via fe80::13:10ff:fe07:1158 dev eth0  proto static  metric 1024 

Where 2a00:1450:400f:800::XXXX are different incarnations of 

Could keepalived (VRRP) be a solution? What is everyone else using?
