Its not possible to add a ipv6 70 route
vyos@gw# set protocols static route6 2a01:4f9:2a:de4:4::/70 next-hop XX interface eth1
2a01:4f9:2a:de4:4::/70 is an IPv6 host address, not a network address. Did you mean 2a01:4f9:2a:de4::/70?

I used a /70 because i obly get a /64 net which i have to split into smaller nets.
It works fine adding the route with the linux route command.
