Packet Tracer DHCP server on router issue

[adite]

Hello, i can't make DHCP on routers work. In simulation DHCP packets don't even enter the router so i'm lost.

I tried to configure DHCP on RDHCPV11 for vlan11, RDHCPV12 for vlan2 and R9 for vlan17.
Can someone help me to resolve this issue? Any help or advice will be appreciated.
Packet tracer file is attached to this post.

Thank you.

Hello,

the GigabitEthernet0/1 interfaces on the switches connected to the routers need to be trunks.

Attached the revised, working file.
