Help! DHCP issues

Under the Shows router at the bottom I seem to be having issues. I can not ping the router from the laptops and can not successfully assign DHCP to those devices either. Please help!

Hi 

 

Two mistakes


1- The upstream interface is wrong.
Switch the serial cable to interface 0/3/0 of the Show router and power up the interface.
2- On the switch connected to the Show router, you must leave the f0/1 interface in trunk mode.

 

After these 2 changes, the PCs get addressing.

Hello
See attached working PT file, the issue you had was that the last rtrs serial interface was not working correctly so that was changed and also the switch interface connecting to the last router required to be trunked, lastly on all of the rtrs, I disabled auto summarization and enabled rip version 2.
