DHCP on IRB Interfaces

Hi,

I am using EX 4300 running 18.1R3-S6.1. I configured DHCP Client on IRB Interface (vlan 1000). I have a DHCP Server connected in that VLAN. I do not see any DHCP activity on the EX 4300. Its stuck in INIT state forever.

root@Juniper1> show configuration interfaces irb unit 1000
family inet {
dhcp;
}

{master:0}
root@Juniper1>

root@Juniper1> show dhcp client binding
IP address Hardware address Expires State Interface
0.0.0.0 dc:38:e1:51:ac:41 0 INIT irb.0
0.0.0.0 dc:38:e1:51:ac:41 0 INIT irb.1000
172.16.10.132 dc:38:e1:51:ac:42 9535 BOUND vme.0

Please let me know if I am missing something.

Thanks in Advance.
