dhcpd.conf logical hierachy

[Narcis Garcia]

Any way I define the static pool, error messages occur.
This is the only configuration I've reached without errors when a known
host connects, but I might not be defining subnet/interface where static
cases are attached to:

subnet 172.16.0.0 netmask 255.255.0.0 {
        option subnet-mask 255.255.0.0;
        option routers 172.16.20.100;
        option broadcast-address 172.16.255.255;
        option domain-name-servers 172.16.21.61;
        pool {
                # IP range to be assigned dynamically
                range 172.16.20.150 172.16.20.189;
                allow unknown-clients;
        }
}
group MyReservations {
        option subnet-mask 255.255.0.0;
        option routers 172.16.20.100;
        option broadcast-address 172.16.255.255;
        option domain-name-servers 172.16.21.61;
        host printer_1 {
                hardware ethernet 00:11:22:33:44:55;
                fixed-address 172.16.20.201;
        }
}
