This isn't OSPF troubleshooting video.
Are you able to solve the problem yourself?
In this topology.
We've been told that rather one on the left is not able to ping the loopback of a router for.
Rather for has a loopback interface of 4.4.424.
So let's test whether.
Right.
One can ping that loopback address and it looks like it can't.
Can you solve this lab?
Download the packet, trace a file and see if you can solve it.
What's the problem and what's the solution to this lab?
Now I want to give you a tip.
In this lab, you may encounter a problem with packet tracer rather than a pure OSPF issue.
When you have a look at router four, you may encounter a problem related to packet tracer.
So if you get things partially working, but you can't get it to work fully.
Have a look at my next video for the solution.
There's no point spending a lot of time troubleshooting a packet tracer issue.
You need to learn about Cisco networking, not packet tracer problems.
So if you're struggling with this troubleshooting lab, have a look at my video for the solution.
In the next video, I'll show you how to solve this lab, but see if you can solve it yourself.
Download the attached packet of tracer file and try and work out where the problem is and fix it and
get the lab working.
