So we've been told that rather one is not able to ping rather four.
So here's rather one show IPV six route.
We can see that the IP version six routing table contains a directly connected network as well as a
static route.
This is a static default route.
So can router one ping router to.
Yes, it can.
Can it ping router four and no, it can't.
So it looks like the information that we've been given is correct.
Trust but verify, as Ronald Reagan said, always check that what you've been told is true.
So in networking, it's always a good idea to verify the information you've been given.
So again, show IPV six route.
We have a static default route, can write a one ping 2001 colon two colon colon one.
This IP address on router two.
Yes, it can.
Can it ping router three?
Yes, it can.
What about this IP address on router three?
Looks like it can't ping that IP address.
Now, what we could also do is do a trace route to router four and see how far the traffic gets.
After this point, it looks like the traffic only gets to router two.
It doesn't get any further.
So even though rather one can ping both this IP address and this IP address, a trace to router for
breaks at router two, which tells us that there's probably an issue.
On Router two.
So let's have a look at router two.
So he has rather two ping 2001.
Colon three.
Colon colon two.
Right a two can definitely not ping right a for.
What about the IP address on router three?
Can't ping that IP address, but it can ping that IP address on router three.
So show IPV six route.
Can you see the problem?
What's the issue on rather two?
So rather two does have a static route.
It's a default route, which is probably not a good idea.
It's okay to have a default route en route to one and perhaps route of four pointing to the rest of
the network.
But this static default route doesn't make a lot of sense, especially because it's pointing back to
router one.
Now, rather than removing that, I'm going to add a more specific route.
To show you that a more specific route will take precedence.
So I need to use the command IPV six route and I'm going to add that route pointing to router three.
So show IPV six route.
We've still got the static default route in the routing table, but we've also got this more specific
route.
So can router two now ping router four?
Yes, it can.
The more specific route or longer match 64 bits is a longer match than zero bits takes precedence.
More specific route takes precedence so rather to camping rather to fall back on writer one can write
a one trace to root of four.
Yes, it can can write a one ping route of four.
Yes, it can.
So in the exam, they will give you clearer information about whether you should remove the study grant
or simply add a more specific route by adding a more specific route.
Yeah, I've solved the problem.
I can leave the static default Rorschach.
But if I was told to.
Or if I wanted to, I could remove that route and the network would still function because this network
is directly connected to rather two and rather two knows about this network.
Because of this study grant.
So show IPv6 route, that static route is in the routing table.
Right.
A two can stall ping route of four can route a four ping router one.
So he has right of four.
Can it ping right of one.
Yes, it can.
Can it ping router two.
Yes, it can.
So we have IP connectivity in this network to ensure that everything works.
You may want to test.
Connectivity to every IP address in your network in the lab.
To make sure that everything works as expected again in the exam.
Read the question carefully.
So that you complete what's required.
Don't spend time on things that aren't necessary.
So how did you do?
Were you able to complete the lab?
Were you able to troubleshoot the network issues in this lab?
I hope you enjoying these troubleshooting videos.
