This is another OSPF troubleshooting lab.
Now, let me warn you, this is a difficult lab.
So if you don't get it right, don't worry.
I'll show you in the next video.
How do you complete this and work it out and how to fix it?
You've been told that PC one on the left cannot ping PC two on the right.
So here's PC one.
Once again, IP addresses this can ping.
PC two, which has this IP address.
And to confirm that that's the IP address of PC two.
PC two is not able to ping PC one.
Destination host is unreachable.
So I'm capturing packets on this link using Wireshark.
Why is the network not working?
Have a look at the OSPF packets.
See if you can find out what the problem is.
See if you can work out what the resolution is to this network issue.
See if you can figure out just by looking at the Wireshark captures what the issue is.
In the next video, I'll show you how to resolve this issue, explain some things, and show you how
to fix it.
What I'll do at this point is stop the capture.
And then save the shock captures ospf tfrs three.
So download the attached Wireshark CAPTCHA and see if you can work out what the issue is.
