Compressed Config

[Todd Snyder]

Good day,

I'm setting up a new DHCP server, which will serve about 300 new
subnets.  My subnets are all exactly the same:

subnet 172.25.1.0 netmask 255.255.255.0 {
         range 172.25.1.16 172.25.1.254;
         option broadcast-address 172.25.1.255;
         option domain-name "prov0.cfg2";
         option domain-name-servers 172.25.70.16, 172.25.65.33;
         option routers 172.25.1.1; 
} 

And I increment my 3rd octet all the way up to 254.

Same with another network.

Given the sameness of all the subnets, is there a clever way to define
these so each one isn't declared?  Something similar to the $GENERATE
directive in named?  It seems like a lot of work when you have hundreds
of the exact same lines, except 2 numbers changing ...

I'm not fond of the number of lines in the above - my understanding is
that I could do this as well:

Subnet 172.25.1.0 netmask 255.255.255.0 { range 172.25.1.16
172.25.1.254; option routers 172.25.1.1; }; 

And define the rest of the options as a more global scope ... Am I
mistaken?

Thanks much,

Todd.
