Hello, everyone! I'm new here and just have, still, a very basic knowledge of how to use Cisco Packet Tracer. I'm really trying my best to learn, but I got into this problem, and I feel like I don't know what to do anymore. Just really hoping someone might be able to help me from here. I am trying to use a router for inter-VLAN routing in my packet tracer project, but I don't really know if it's gonna work. I've watched YouTube tutorials, but I just really can't find the problem with my configurations. I have 4 VLANs, the 3 are for, like, the different branches, and then one just for management reserve. I have configured the pools on the DHCP server for each VLAN, but when I try to set the PC to DHCP, the request for an IP address fails. I believe I have correctly set the correct ports as well, access or trunk, I think the issue is really on how I've set the DHCP server.
Solved! Go to Solution.

You almost did it.
If you want to work with Router in a stick, you dont create layer3 interface vlans on the switch, leave as only layer2.
The interface towards the DHCP server can not be in trunk.
The default gateway of the DHCP server was wrong.
You can check the file attached for reference.

Thank you so much! Learned new things, will take note of this in the future. Just let my frustration win a while ago, so I didn't know what I was actually doing anymore. Just went with it, I guess.
