Can you answer these questions by interpreting a Wireshark capture?
What I'm going to do here is start a Wireshark capture on this interface, and then I'll start these
routers in the topology.
The reason I want to start the Wireshark capture first is I want to show you the routing protocol negotiation
between those two routers.
So I want to capture that in the Wireshark capture.
Now you get these Wireshark captures as part of this course.
So download the attached to Wireshark capture and see if you can answer the questions.
The first question is which version of OSPF is used in the topology?
So which version of OSPF is used on router one and router two?
Is authentication used?
If so, which type of authentication?
What's the password?
So can you sniff the password from this network?
So by simply running Wireshark and looking at the Wireshark capture, are you able to determine what
the password is?
In other words, what password is used by these OSPF routers?
Which OSPF area is used.
Is it area one, area two or another area?
What are the OSPF router priorities?
Default priority is one.
Which Rada is the designated Rada.
Okay.
So you can see here we've got some OSPF advertisements taking place.
I'll do an OSPF filter so that we only see OSPF messages.
And what I'll do here is stop the Wireshark capture.
This will be the Wireshark capture that you have attached to this course.
So I'll save this as OSPF one.
So download the Wireshark capture and see if you can answer these questions yourself.
In the next video I'm going to show you the answers.
So I will.
Show you how to interpret the why shot capture and then answer these questions.
So if necessary, stop the video at this point or pause the video and see if you can answer these questions
yourself.
There's no better way to learn than to try things yourself.
So again, download the Wireshark capture.
See if you can answer the questions.
Otherwise, continue watching and I'll answer the questions.
