Afternoon
Its working now. Here is the solution;
You have to configure empty declaration for least one of directly
connected subnets (condition accomplished) and all other relayed subnets.
For example:
subnet6 2013:0:0:1::/64 {
}
subnet6 2013:dead:beef:8001::/64 {
range6 range6 2013:dead:beef:8001::1001 2013:dead:beef:8001::1999;
}
