Hi Andrei, Default gateways for IPv6 is always configured with Router Advertisements (RA), no matter what addressing mode is used. Please ensure that:
- you have a virtual router connected to your IPv6 subnet, this would provide RA (and actual router) in your network - accept_ra is enabled in your guest OS: sysctl -a | grep accept_ra -- With best regards, Vladimir Eremin, Fuel Deployment Engineer, Mirantis, Inc. > On Dec 23, 2015, at 12:50 AM, Andrei Radulescu-Banu > <[email protected]> wrote: > > Hi all, > > I’ve been trying for a few days to understand how this should work.
