Radius X mikrotik

I have my server set up perfectly with hotspot dhcp server, with the following options, so the customer libero after the register in dhcpserver-leases as static-only, for which he receives the ip automatically, and after registration in the hotspot.
use network / 30 type:
Client 1
IP-172.16.2.2
MASK - 255,255,255,252
GW -172.16.2.1
DNS - 172.16.2.1

customer 2
IP-172.16.3.2
MASK - 255,255,255,252
GW -172.16.3.1
DNS - 172.16.3.1
and so on …

Then next I want and put these parameters in radius with the system that I am on trial here, if someone can help, thank you.
