> Ipv6 - Ubuntu 12.10 guest Vms looses default route (after it expiration time
> ~ 30 mts) when ipv6.autoconfig parameters are disabled except for
> net.ipv6.conf.lo.autoconf which is enabled.
> Steps to reproduce the problem:
> Create a ipv6 network.
> Deploy Ubuntu 12.10 guest Vms in Ipv6 network which have all pv6.autoconfig
> parameters disabled except for net.ipv6.conf.lo.autoconf which is enabled.
> As part of starting the Vm , we see that the ip route is set in the guest VM.
> Wait for ~30 mt ( expiration time to pass).
> Notice that the VM has lost its ipv6 route.
