This will result in an IPv4 and IPv6 routable mesh network that can survive any one node failure or any one cable failure. Alls the steps in this section must be performed on each node
Note for ceph do not dual stack - either use IPv4 or IPv6 addressees for all the monitors, MDS and daemons - despite the docs implying it is ok my findings on quincy are is it is funky....
this gist is part of this series
Doing this means we don't have to give each thunderbolt a manual IPv6 or IPv4 addrees and that these addresses stay constant no matter what.
