It looks like there is no support for IPv6 tokenized identifiers in the 
existing ifcfg scripting (report an upstream bug?) so you would have to 
wait for Red Hat to produce a solution, patch the scripts yourself (set 
the interface's token just before bringing the interface up in 
ifup-ipv6) or remove their use and write your own systemd.network(5) 
unit for all the interfaces -- perhaps one of the two latter things 
while waiting for the former.
