here it is:
master config:
failover peer "dhcp-failover" {
        primary;
        address 172.24.1.5;
        port 520;
        peer address 172.24.1.6;
        peer port 520;
        max-response-delay 60;
        max-unacked-updates 10;
        mclt 1800;
        split 128;
        load balance max seconds 2;
}
