Another very important skill that you need is the ability to troubleshoot networks.
This is an OSPF troubleshooting lab.
See if you can work out by looking at the Wireshark captures.
What's the problem in this network?
So I'm going to give you this Wireshark capture.
So have a look at the attachments, depending on what platform you're using and then download this Wireshark
capture.
I'm going to start the Wireshark capture on the link between the switch and the router, so between
switch one and router two so we can see the Wireshark capture.
I'll start up these routers now.
The issue in this network is that PC one is not able to ping PC two, so PC one can't ping PC two for
some reason.
Okay.
So here's PC one.
IP address of PC one is ten 111.
Can it ping pc to.
At the moment it says host unreachable.
His PC, too.
Now I know these IP addresses, but notice there's the IP address of PC two.
Can it ping PC one?
At the moment we've got destination host unreachable.
So have a look at the Wireshark capture and see if you can troubleshoot.
Why?
The network is not working.
I'll stop this Wireshark capture at this point so it doesn't get too big.
This is the Wireshark capture that you need to use.
So.
OSPF Troubleshooting Lab one.
So see if you can find out why OSPF is not working.
What's the problem in this network?
Download the attached Wireshark capture.
See if you can troubleshoot it.
In the next video I'll show you the answer to this by troubleshooting the network through this Wireshark
capture.
