You can probably do it with classes and a pool within the subnet that
allows just these hosts.
class "cpe_1234" {
match if option agent.remote-id = 00:11:22:33:44:55;
spawn with option agent.remote-id;
lease limit 2;
}
subnet 192.0.2.0 netmask 255.255.255.0 {
option routers 192.0.2.1;
# ... more options
pool {
allow members of "cpe_1234";
range 192.0.2.10 192.0.2.11;
}
}
I haven't tested this but that's how I think it should work. You'd of
course have to remove the host declaration.
And you may want to add "stash-agent-options true;" too.
