DCHP failed. APIPA is being used problem in packet tracer

[AdamK729]

"Hello,

I am working on a lab assignment of a 3-floor network pattern in Packet Tracer. Although DCHP config is working for floor 2 and 3, whenever I change the IP configuration of any device of floor 1 from static to DHCP, I receive an error message stating, 'DHCP failed. APIPA is being used.' I am attaching the drive link of the zip file to this post.https://drive.google.com/file/d/1QySS_n5iumUBJcFwG9wKL9hJKl-Q_9E-/view?usp=sharing

Hello @AdamK729 

modify sub int on F2 Router.

Subnets towards Floor 1 are connected to Gig0/1 interface, not Gi0/0.

So modif Gi0/0.18 Gi0/0.19 and Gi0/0.20 to Gi0/1.18, Gi0/1.19 and Gi0/1.20 like this:

After that, hosts on Floor 1 should have IP ADD from DHCP.
