Request Timed Out when pinging PC from different routers

[CW Lee]

Hello, I'm new to packet tracer, I can't figure out why I'm not able to ping the PCs 

[MichaelMcCoy]

Hello, So I was able to get pings working without any modifications to configurations.  Is there more to the issues that you are facing?

Which PC's are failing to respond to ping?

I apologize.  I was initially pinging in the same subnet.  I was able to duplicate your problem and the fix action is that you need to add a gateway on all the PCs.

I added the gateway to PC0 and PC4 and was able to generate icmp traffic throughout the network.  

Please mark this as the solution if it helps you solve your issue.

Thank you so much!

Absolutely, have a great day!

Hello,

since I was working on your file, I might as well post what I have come up with. In order to avoid forgetting or misconfiguring PC addresses and gateways, it is usually a good idea to use DHCP servers. You can use the IOS routers for that. I have configured DHCP pools for all LAN networks on all routers (make sure the corresponding access ports on the switches are configured with 'spanning-tree portfast' in order to avoid DHCP timeouts on the clients).

Attached the revised file.
