Packet Tracer: DHCP Server not assigning IP's to other networks

SteveScorse

Level 1

Hi, I am very new to CPT and Networking in general so I apologise in advance for any silly questions.

I have configured a DHCP server to assign IPs to the networks in my topology, however, they only assign to the network the server resides in (Floor 2). I am able to ping the routers in the other networks so I assume my routing is fine (I am not too sure though). And I believe my DHCP pools are configured correctly, so I am unsure where my issue lies. Any help would be greatly appreciated, thanks.

Attached is the project file: (NOTE: This file is major WIP, and my first ever network, so is quite messy so I apologise if it is hard to navigate)

Many Thanks

DHCP server is missing its default gateway IP and some PCs are not set up to get IP from DHCP. 

But main issue is that routers need ip helper-address 192.168.1.2 on interfaces facing away from actual DHCP server. DHCP packet is Broadcast request and rotuers stop those Broadcasts. Anytime u have a L3 device between DHCP server and PC client, next L3 device needs ip helper address command

Also, if u plan to use RIP, always use version 2 and no auto summary.
