Do we help troubleshooting Packet Tracer problem?

I did my chapter Packet Tracer activity. This one is about network convergence. I completed that by issueing the network command. But somehow the newly added PC2 cannot ping router 3 and I cannot figure out why.

I'm being very uptimistic that some of you would also have Packet Tracer. I've also attached my completed Packet Tracer file so you can troubleshoot. Because the forum here only allow .doc or image attachments. I added .doc to the name file. Please delete that so you can run the file in Packet Tracer.

I know I'm asking a big favor. But I don't how else I can figure it out. Thanks.

Here are some output if it helps.

    Can you just post running configs of the routers your having issues with. I'm having difficult changing file format.

    Just a hint: Check the IP address/mask of the PC2 and the Interface Router2 that is being used as the default gateway, what's wrong there?

    Did you discuss with your instructor?

    Unfortunately I don't see anything wrong.

    PC>ipconfig

    Look again. You used show ip int br but that isn't checking everything atorven told you to check...

    Router3#show interface fa0/1
    FastEthernet0/1 is up, line protocol is up (connected)
    Hardware is Lance, address is 0000.0ce8.5302 (bia 0000.0ce8.5302)
    Internet address is 12.0.0.1/24

    PC>ipconfig

    IP Address......................: 12.255.255.254
    Subnet Mask.....................: 255.0.0.0
    Default Gateway.................: 12.0.0.1

    Edit: I had the problem bolded but removed the bold because I want you to really look. If you're still not getting it, I'll give you another hint.

    I assume the PC is on R3's fe0/1 interface, if so you should make sure (using ip routing logic) that the PC knows it can talk to R3 directly. Based on the config you posted, the PC thinks it can't talk directly to R3.

    PC Subnet Mask =/8
    R3 FE 0/1 Subnet Mask =/24

    should explain why your ping isn't working

    Look closely at your configuration again mate. Try and concentrate on just the area between routers interface and pc you are pinging from. The above lot are giving you a lot of clues, post on here once you think what it is buddy. Good luck.
