I can't ping from pc2 to pc0. Its says "Reply from 150.7.32.1: Destination host unreachable." I checked the routing table and there is no route to PC0. How could that be? All we PCs are configured correctly. Any ideas?

    Might want to do a little more reading on EIGRP redistribution.
    An expert is a man who has made all the mistakes which can be made.

    I just now used this command....

    router eigrp 100
    redistribute ospf 100 metric 10000 10 40 10 1500

    I now see the in the routing table of router2 a route to 150.7.0.0 but now when I ping that computer it :"times out."

    When you redistribute, you need to redistribute in both directions. Just as you redistributed OSPF routes to look like EIGRP routes, you also need to redistribute EIGRP routes to look like OSPF routes on that same router that you're doing the redistributing on.

    Edit: Ignore that. I just noticed that you did indeed do that on router 1.

    You said you can't ping from PC2 to PC0. Can you ping in the other direction from PC0 to PC2?

    Also, can you do a sh ip route and show us the routing tables of those three routers?

    Going from PC0 to PC2 I get "Reply from 150.7.0.1: Destination host unreachable."

    Can you upload the packet tracer file?

    You should be able to do it the same way you uploaded the picture of the diagram.

    It tells me invalid file. Must be a picture extension, like bmp,jpeg,etc...

    It has to be something with my redistribution because Router0 hasn't learned any routes from router1. I just don't see how to fix it.

    Solved.

    Changed redistribute ospf 100 metric 10000 10 40 10 1500 to
    redistribute ospf 1 metric 10000 10 40 10 1500

    Ha! Adding those extra numbers will do it. Can't believe I didn't see that.

    bah i don't have the latest version so can't open it. I'm sure someone will be a long to clear it up for you.

    I'm not sure this exactly the cause, btu OSPF will only redistribute CLASSFUL subnets by default.

    Problem is on Router 1

    I've seen a few problems like this posted in the CCNA section recently. Have they beefed up the CCNA to include thongs like redistribution and multiarea OSPF, or is it just that people are expanding their horizons and having a go? ( which is a good thing)

    I took the CNA courses a year ago and took the 640-802 last November. In class we covered that these things existed, but that was the extent of it. So I would say that it's the later.

    redistribution and multi area are not covered in the CCNA exam. But many of the study materials used touch on these subjects, and i guess being the curious bunch us IT folks are, we usually dig a little deeper :)

    In the Routing and Switching Lab class I took as part of my degree program, we had to perform redistribution between EIGRP and RIP in one of the labs even though we hadn't done it before. So we kinda learned it on the fly.
