Hello. Welcome back to ice. Indy one, interconnecting Cisco Networking devices. Part one
00:05
this is Episode 744 Troubleshooting I p version six addressing and routes
00:10
on Trend era One of your instructor for this course, the last video we went over configuring static rows for I p version six
00:17
in this episode of recovered seem basic troubleshooting methodologies to help you during the examined during riel life.
00:24
So we'll be going through some troubleshooting commands as well
00:27
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.
00:39
All right. It is See
00:44
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
00:58
10 would be a 11 would be be.
01:02
And what would be C?
01:04
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
01:23
cables might be dead or you're killing me bad. You might have
01:26
a port in a no, shut her in a shut status or shut down status.
01:30
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,
01:49
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,
02:02
and that's where we can run the ping six. Or remember, I had to run the ping
02:07
Ah space. Hi P V six command.
02:10
We can check the ICMP packets to make sure that reaching the target
02:15
soaping clothes start, start close, run far you can run a trace Road Command
02:21
to check to see if it's working properly.
02:23
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.
02:38
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
02:46
somewhere on one of my writers. So we're gonna go ahead and troubleshoot it.
02:52
All right, So we're gonna start with Ryder too. Here.
02:55
So let's start with number one. Show I, P. Person six
03:00
interface brief.
03:02
First Internet would be the
03:06
landside
03:07
that ISS facing
03:10
the land. I guess
03:13
that was an open up. Our serial is in and up and up.
03:16
Let's check the documentation that I p address is correct for the land side.
03:23
That is correct for the win link.
03:27
Eso was trying ping the other outer,
03:30
and we already got the I Q 6 2112 Maybe CD 21
03:42
Okay. Make sure you got it right here.
03:45
We're going one.
03:46
Yeah, that's right.
03:49
So we're not picking our one, but we're open up right now.
03:53
Let's check our I. P. Was treated round table for we.
03:57
We move the council cable here.
04:00
So it was static drought going over to that one for the router. One land.
04:04
We have a connected routes for
04:09
the two. Network
04:12
on way have connected for three, which is fine.
04:16
All right. So it's going to put in a broader one. See what you find.
04:19
All right, So start with interface status. Show I P. Version six, interface brief
04:28
Fast Season 00 has a global address, ABC 11
04:34
Okay, that's the correct.
04:36
And a serial interface doesn't have an I p. Address.
04:41
Okay, let's step to write their figure terminal into Sears. There is zero.
04:47
Do I hear four. Address? Check the documentation
04:51
and I love the question. Mark 2112 ABC to corn one
04:58
slash 64.
05:01
Let's go ahead and shook the
05:05
face brief again.
05:09
All right, so let's go ahead and try. And ping, That's router to now.
05:14
Beavers for 2112 a BCD to Colin. Colin too. OK, so it's all come with Roger to. Now,
05:24
what's check to see if we can hit the other one?
05:30
All right, so it's working.
05:35
So one thing I'll show you here. I want to show you what it would look like if
05:41
papers around what it would look like if we didn't have this static route going to number three.
05:46
And what? Another problem that could persist.
05:53
She d three
05:57
three comfortable in 64
06:02
Ah shows.
06:06
Sure. I have you for six rounds.
06:14
All right,
06:16
so here I have added in a
06:19
merrick's kind like the eye perversion for a gateway of last resort.
06:24
It is that, um
06:26
kind of like the fail safe route that he stay. We configure.
06:30
So if you see a problem with this
06:31
and I hope you d'oh, that's good, because the
06:36
static route for the fail safe is going out too fast. Ethernet.
06:41
So if we do anything,
06:43
I see high fevers or six
06:46
2112 baby C d three
06:50
one.
06:54
No,
06:55
she'll run.
06:57
Include
07:01
who'd route?
07:05
So I'm gonna remove this rather a quick
07:09
Tiu. No,
07:13
Sure. Six Brown.
07:17
Okay, it's gone this time.
07:20
See?
07:23
So a B c D 3.1.
07:29
All right, so this time is gonna fail because it's sending those pings out the
07:32
fast Ethernet interfaces we see here.
07:35
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.
07:44
Come on, Corn 64. What we're gonna actually do is just change that
07:47
that gateway last resort that fail safe. So go ahead and configure terminal
07:53
I was doing I prefer six routes and remember the
07:58
thing or the command for the
08:00
prefix for it.
08:01
All right. It was coming on
08:05
slash zero,
08:09
and we'll give it the interface of cereal 000
08:16
You know, if we do a show like your six routes
08:20
we should see
08:24
is going out both.
08:26
So see if this works, really? We would want to remove the fasts. Ethan. I want
08:31
inactive. 6 2112 a. B c. D.
08:35
Three calling one.
08:41
So here we're getting kind of skipped because it's it's sending
08:43
out both of them.
08:46
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.
08:58
So zero phasers hero
09:01
and let's try to get a ping.
09:05
All right, now we're using that gave a last resort shooting right over to it. Everything is working properly,
09:15
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
09:24
have you figured out.
09:26
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
09:39
Go ahead.
09:43
All right. It is a 9 45 So if you remember,
09:48
the seventh bit gets
09:50
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,
10:03
which is 10101010 Yeah. Um, and flip that third bits is just gonna get one
10:11
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.
10:24
So in the next module, we're gonna go with the vice manager. Organ it, sis. Log network time protocol. I waste management.
10:31
And guys, this is the last module. So I really look forward to
10:35
senior this last one.
10:37
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
