Just asking.. The qfx acting the layer 3 "helper" for the devices connected to your system do you have a vlan option option 82 setup for it ?
I only ask as I have had things not work the way I expected as I have setup the Vlan fwd option 82 stuff but also the layer 3 fwd dhcp-relay for the same vlan being supported by the irb ..
set vlans Group4 l3-interface irb.999;
set vlans Group4 forwarding-options dhcp-security option-82 circuit-id use-vlan-id
set vlans Group4 forwarding-options dhcp-security option-82 remote-id host-name
Yours.
set forwarding-options dhcp-relay relay-option-82 remote-id
set forwarding-options dhcp-relay server-group 4-srvs 10.1.1.2
set forwarding-options dhcp-relay group 4 active-server-group 4-srvs
set forwarding-options dhcp-relay group 4 interface ge-0/0/1.0
