Unable to add IPv6 option to dhcp config file

[Glenn Satchell]

Ok, that error is easy to fix: "option definitions may not be scoped" 
means you must define the option in the global scope, not in the subnet 
scope.

Move the option definition line out of the subnet into the global scope, 
ie put it *before* any subnet definitions. You can still fill in the 
values in the subnet scope though, you might want different values in 
different subnets for example.

option OPTION_6RD code 201 = array of integer 8;
subnet ... {
	option domain-name ...
	option OPTION_6RD 
201,24,28,64,192,168,1,100,32,01,18,52,0,0,0,0,0,0,0,0,0,0,0,0;
	...
}
