Hello. Welcome back to ice. Indy one, interconnecting Cisco Networking devices. Part one
this is Episode 744 Troubleshooting I p version six addressing and routes
on Trend era One of your instructor for this course, the last video we went over configuring static rows for I p version six
in this episode of recovered seem basic troubleshooting methodologies to help you during the examined during riel life.
So we'll be going through some troubleshooting commands as well
and is always quick pre assessment here. Hopefully I should know this one. What is the hex character of the binary one? 100 Give me a few seconds.
All right. It is See
or option D and letter C. How are you to say so? You think about the, uh what is given you is you have the eight place is one and the four places one meaning 12 and
10 would be a 11 would be be.
And what would be C?
So is a quick troubleshooting methodologies. You're gonna want to hit up. Start with simple. Always start with simple start with layer one, as we say, Check the interface status. Make sure that you're not trying to troubleshoot your routing table before they even check that your interfaces are opened up because
cables might be dead or you're killing me bad. You might have
a port in a no, shut her in a shut status or shut down status.
Um, after you've confirmed that everything is open up that your ports are no shot to that, you know, they're working properly like that shakthi I p address. Make sure that is configured with the documentation that you're given. Um, is it a manual configuration to dead administrator? Mess up or fat finger the,
You know, the I P addresses, It's a D a C P. Address problem where the server might be given you the wrong I p um, if his d h e p check to see if he really agent is set up, if it's off the sub net, are you getting your I p address from slack? You know,
and that's where we can run the ping six. Or remember, I had to run the ping
Ah space. Hi P V six command.
We can check the ICMP packets to make sure that reaching the target
soaping clothes start, start close, run far you can run a trace Road Command
to check to see if it's working properly.
Um, and then finally, we'll check the I p v six routing table to make sure that our static droughts, air configured, are connected roads or don want to check out prefixes? Make sure prefixes air good or prefixed length checks. Check the next hop address.
See if we have, ah, gateway of last resorts. Check all those kind of things. So I've gone ahead and messed up one of my configurations
somewhere on one of my writers. So we're gonna go ahead and troubleshoot it.
All right, So we're gonna start with Ryder too. Here.
So let's start with number one. Show I, P. Person six
First Internet would be the
that was an open up. Our serial is in and up and up.
Let's check the documentation that I p address is correct for the land side.
That is correct for the win link.
Eso was trying ping the other outer,
and we already got the I Q 6 2112 Maybe CD 21
Okay. Make sure you got it right here.
So we're not picking our one, but we're open up right now.
Let's check our I. P. Was treated round table for we.
We move the council cable here.
So it was static drought going over to that one for the router. One land.
We have a connected routes for
on way have connected for three, which is fine.
All right. So it's going to put in a broader one. See what you find.
All right, So start with interface status. Show I P. Version six, interface brief
Fast Season 00 has a global address, ABC 11
Okay, that's the correct.
And a serial interface doesn't have an I p. Address.
Okay, let's step to write their figure terminal into Sears. There is zero.
Do I hear four. Address? Check the documentation
and I love the question. Mark 2112 ABC to corn one
Let's go ahead and shook the
All right, so let's go ahead and try. And ping, That's router to now.
Beavers for 2112 a BCD to Colin. Colin too. OK, so it's all come with Roger to. Now,
what's check to see if we can hit the other one?
All right, so it's working.
So one thing I'll show you here. I want to show you what it would look like if
papers around what it would look like if we didn't have this static route going to number three.
And what? Another problem that could persist.
three comfortable in 64
Sure. I have you for six rounds.
so here I have added in a
merrick's kind like the eye perversion for a gateway of last resort.
kind of like the fail safe route that he stay. We configure.
So if you see a problem with this
and I hope you d'oh, that's good, because the
static route for the fail safe is going out too fast. Ethernet.
So if we do anything,
I see high fevers or six
So I'm gonna remove this rather a quick
Okay, it's gone this time.
All right, so this time is gonna fail because it's sending those pings out the
fast Ethernet interfaces we see here.
So we're gonna go ahead and let this fail, and we don't actually have to configure the route for 2112 a B c. D. Three.
Come on, Corn 64. What we're gonna actually do is just change that
that gateway last resort that fail safe. So go ahead and configure terminal
I was doing I prefer six routes and remember the
thing or the command for the
All right. It was coming on
and we'll give it the interface of cereal 000
You know, if we do a show like your six routes
So see if this works, really? We would want to remove the fasts. Ethan. I want
inactive. 6 2112 a. B c. D.
So here we're getting kind of skipped because it's it's sending
So that's one thing that's weird. If you notice that now, hopefully you should know what to look for. Look for two *** ways like that. So we're gonna do is do a no active six routes.
So zero phasers hero
and let's try to get a ping.
All right, now we're using that gave a last resort shooting right over to it. Everything is working properly,
and so I'm so to recap, we went and looked at some troubleshooting commands of what, through the methodologies for its We had a couple bad I p rows. We had bad I p's
have you figured out.
And quick pull assessment here, making use more binary Matthew for a highlight leaf. What is the you I 64 of Mac address a B 45 64 5 delta dot f one a. C
All right. It is a 9 45 So if you remember,
the seventh bit gets
inverted, meaning it's if it's a one, it turns to 00 it turns to one on that it is going to be 1/3 bits of the second hex character or the seven total bit. However you want to think about it,
which is 10101010 Yeah. Um, and flip that third bits is just gonna get one
101 1/3 flipped 1/3 bit 1001 Which would be not. And then we split. We throw that f f f e into the middle of the Mac address.
So in the next module, we're gonna go with the vice manager. Organ it, sis. Log network time protocol. I waste management.
And guys, this is the last module. So I really look forward to
senior this last one.
And as always, if you have questions, you know, feel free to shoot the message. Otherwise, thank you for watching this module. Fordice Sr s, um
