Having trouble pinging computers

Hey guys.

 

So I've been looking for a solution online for days as I am having trouble pinging from computers to computers. In this case, I ping PC1 from PC9 and I got replies, but with "Destination host unreachable". If I try pinging from PC1 to PC9, I got "request timed out" messages. This happens to all of the computers as well. I tried playing around with the ip address, subnet mask, eigrp protocol, etc....but it didn't work. I've attached the file below for you to review. Could you guys help me correct the errors/mistakes by modifying it? Because my submission is due tomorrow and I don't think I have enough time to figure it out myself. Please help! 

 

Thank you.

Re: Having trouble pinging computers

Hello,

 

here is what was misconfigured:

 

1. On the main router, the IP addresses on interfaces Serial0/2/0 and Serial0/3/0 were switched, so Router 4 and Router 5 had no connectivity and did not receive any (EIGRP) routes.

2. Interface FastEthernet0/0 on Router 1 had the wrong subnet mask, /30 instead of /24.

3. Some routers did not have EIGRP configured at all.

4. Several PCs had the wrong IP address and/or the wrong default gateway configured.

 

You can configure the IOS routers as DHCP servers, in order to avoid having the wrong IP addresses on your clients. Here is an example for Router 1:

 

ip dhcp excluded-address 192.168.10.1

!

ip dhcp pool LAN

network 192.168.10.0 255.255.255.0

default-router 192.168.10.1

Hello,

 

basically, there were a lot of misconfigured IP addresses, switched interfaces, and missing EIGRP networks. Have a look at the revised file...

Hello

Your two nodes PC0-PC1 had incorrect addressing, router 1 had incorrect subnet address for you lan ,router 5 eirgrp interface wasnt active and the eigrp processes had auto summarization enabled ( disabled by no auto-summary)
