EX4300 most simple DHCP relay config?

Hi all,

We have couple EX4300 switches in VC configuration with ELS software version 14.1X53-D35.3.

They are used as a distribution switches and I'm trying to simplify current DHCP relay configuration.

I'm coming from Cisco world where you would only need to define ip helper-address under vlan interface to make DHCP relay configuration work.

With our current confguration everything is working but Junos is creating this subscriber database or binding database, whatever is right term.

And it also creates these Access-internal routes to routing table for each individual DHCP binding.

I would like to get rid of this behavior and make setup as simple as possible, like in Cisco.

forward-snooped-clients configured-interfaces;
overrides {
    allow-snooped-clients;
}
server-group {
    windowsservers-group {
        10.10.2.1;
        10.10.2.3;
    }
}
group office-pc {
    active-server-group windowsservers-group;
    interface irb.20;
}
group office-voip {
    active-server-group windowsservers-group;
    interface irb.21;
}

When installing EX switches we discovered that we needed these options so that lease renewing would work:

forward-snooped-clients configured-interfaces;
overrides {
    allow-snooped-clients;

And this had to be configured same way to our core switches where our DHCP servers are hosted. Core switches are also EX4300 with just different port configuration.

So, question is: What configuratio would stop Junos creating DHCP binding database and work just like Cisco does? So that unicast DHCP renew requests would go thru to server also.
