In this practical lap we'll take a look to this 30 growling configuration together.

We have four steps to configure for these lab guys in the first step

Levy saying as to configure geek 0 0 interface of all or others with proper IP address compatible with

their names.

So we need to find the compatible IP address for the kids 0 0 interface and that should be compatible

with the names of the others too.

Also in the second step lap saves us to configure geek 0 1 and 2 interfaces of all rather thus showing

the figure and in the third that we are going to configure static routing and provide full connectivity

between all networking devices as is shown in the figure and in the first step we need to run Shaw IP

protocols and show IP rad commands and we need to check it out put

Okay let's go let's talk something about the topology to we have four pieces.

P.S. 1 3 am 1 2 3 and 4.

We have 4 Switch switch.

1 2 3 4.

And we have 4 Rather's rather 1 2 3 and 4.

We have different networks as you can see that we have time for the 1 eleven network four here.

32 network four here for the 4 network 4 here and 2 in it to network 4.

Here and we have different networks between the Rather's tools so we have them for the 1 12th network

for here between rather 1 and 2.

We have 13 we have 24 and we have 34 between rather three and rather four as you can see that in the

picture

we have the IP addresses or this switch and this subnet mask also.

So what that does mean

that means that we can derive something huh.

I think

could we define the network ideas for here using this information.

I think yes

10 for the one eleven five slash 30 slash 24 means we have a network idea of eleven that 0 4 here

also to tune it to the 0 and 40 for that 0 and 2 and 3 that sewer for the portion of this network so

what that is mean if I have a network idea of eleven that zero slash 24 that means I can use this IP

range for this network

run to

two hundred and fifty four right

but because of questions saying ask that all routers all routers this 0 0 interface should have a compatible

IP address with their names

I need to assign the eleven that one IP address for Dick 0 0 because this is rather what I need to assign

the thirty three the three four here because this is rather three I'm just changing the last octet as

you can see that

I need to use to and is who the two and folded up four for the four that for four here and please pay

attention that these IP addresses that I have given to the geek 0 0 ports should be configured as the

default gate they on our PCs gateway of this P.C. should be this IP address right.

All right let's go and configure the key 0 0 interfaces as shown in there figure I'm going to configure

a lemon that one for rather one I'm going to configure thirty three that three four rather three forty

the four that for four rather four and twenty two that two for rather two and let's go Packet Tracer

time

here is my topology that I draw in packet sir and I'm going to configure to geek 0 0 interfaces of the

writers.

Let's go I mean around the ranch and I'm getting into the enablement from now on beginning just from

now I'm not going gonna explain that how I go into the enablement why I joined to the config more because

I talked about a lot of times what these comments are doing.

You can check the previous lapse and learn about them also but from here beginning from here I'm not

gonna tell you that.

Hey guys.

Enable command makes us moving from user mode to privileged exact month all right.

Because you know it anymore.

Okay let's get into the conflict mode and let's say that interface geek 0 0 and I'm going to give the

IP address of 10 41

11 and one for rather one but well I forgot it here.

I just warns me that that's an incomplete comment.

I guess is right because I didn't give the summit mask so I'm giving my subnet next to

Celeste to any 4 which means to verify if you've ever to provide zero enter.

And please don't forget to say no shot brother 1 is OK.

No I'm going to configure rather to

see I enable config interface.

0 0 0 IP address turn for the 1 2 an ID 2 that 2 2 5 5 2 5 5 2 5 5.

0 and no shirt.

Pretty cool.

It's time to take a look to the rather 3 2 Seelye

in maybe now in a V enable enable county in the first week 0 0.

IP address 10 41 30 two that thirty three that three and 2 5 2 5 2 4 5 0.

And no shot

I'm in the rather 4.

Lastly

and no show.

It's okay.

That's pretty cool.

And I comb for your

all my dick 0 0 in the face of all others with proper IP address and they are compatible with their

names Whoa.

That's great.

The first action was taken and let's get into the second step.

In the second step we need to configure geek 0 1 and 0 2 in the faces of Rather's as shown in the figure.

But what we see in the figure here just you can see the network I.D. for example the network idea of.

Here is

10 for the 1 12th 0 and slash 24.

But with that format something is riding on the interfacing interfaces.

There are some labels that one means that news

that one for this interface.

The last octet will be one that to me is use for the one 2 with that 2 for this interface.

So now it's time to configure these interfaces on all routers as shown in the figure.

Please keep in mind that the last of that will be valid for either 1 2 4 rather 2 3 4 rather 3 and 4

4 rather 4

Packet Tracer time.

And let's get into the key 0 1 interface.

First

Okay it's time to take a look to rather from launch first

interface 01 01.

I need to configure an IP address of IP address them for the 1 13 and 1

and No shot.

Let's go to the interface

0 0 2 and my IP address for here will be to have that.

Okay

as you can see that gig 0 2 is 12 that 1

and gig 0 1 is 13.

That what pretty cool pretty straight forward there's no problem we can easily implement the IP addresses

as shown in the figure right son.

Let's take a look to the rather two now.

In rather too I'm going to configure to f that 2 for Dick 0 2 and 20 for that 2 4 6 0 1.

Let's go

either ways geek 0 2.

Together 2

and shut then I'll go to the 0 1

gig 0 1 IP address will be this time 24.

That 2

and no shot right.

I'm seeing a problem but I'm not gonna tell you that now.

Let's go to the rather three now I mean rather tree and let's go to the interface geek.

0 1 which is gonna be IP address

and shut and let's go to the interface geek 0 2 which will have an IP address of

thought for that 3 and with a subnet mask of 2 4 5 2 4 5 2 4 5 0

and the last step is we are gonna take a look to the rather far

interface geek 0 1.

We'll have an IP address of 24 for

no shot and interface Duke 0 2 will have an IP address of

30 for that for

and notion.

As I told you that I'm seeing a problem in the figure

please pay attention that everywhere is in green.

That means there's not a physical problem between that devices but I have red dots between rather one

and rather two which means there is a physical problem between these two riders.

So to fix it I need to check the configuration of the 0 2 for both rudders that score

0 2

please remember that to either to verify the interface

configuration I'm using show IP interface grief comment and as you can see that for Dick 0 2 I have

a problem.

The problem is status of this port is still administratively down which shows me that I forgot to type

no shut

gig 0 2 and No shut.

And as you can see the blind protocol on the interface digs zero to change data up which means physical

problem is not with us anymore and everywhere is green

and that means we have completed the second step.

To also

alright pretty cool I know that that's not an easy lip.

For you guys but you learn lots of things when you accomplish and where you learn the details of this

lab.

All right let's start with the third step.

Third step tells us for use static routing or all routers to provide full connect to 80 between all

pieces in the net work not our that's the real most important part of the left and First we need to

understand what's going on.

Okay to comb for your aesthetic grout for example let's say that I'm going to configure a static rock

for rather three

four rather three but which networks should I teach two rather three and where I'm gonna send the packet.

I have two questions

and four other one.

Which networks should I teach for the other one.

And where I should send the packet first.

I need to define this.

Then I'm gonna write the static grounding comments today.

Rather's as you'll remember from our first sections.

Well I told you is Rather's already known the networks which they're directly connected for example

rather three is directly connected to here.

Here and here so I don't need to say.

Rather treated.

Hey man if you have a picket which destination is thirty three that zero network sent Packer to somewhere

because rather already knows here.

Rather says that on my dick 0 0 interface I have third to 33 the zero network already.

Let's take a look to the rather for rather four is directly connected to here here and here so I don't

need to say two rather four.

For example if you have a packet which destination is twenty four that zero network you need to send

packet the some interface because rather all four already knows that I have four twenty four network

connected to my dick 0 1 interface I don't need to learn it.

OK so

on it to

use static grounding for rather three to teach the networks that rather three is not directly connected

so far rather three I need two static IP riding statements for this that works eleven

twelve twenty two

for 24.

Forty four right cars rather three is not directly connected to this networks and rather three doesn't

know how to get this network's so I'm going to teach these networks two rather three using the static

IP configuration right

let's say that four we have let's take a look while we have for the rather one also for other one I

need to use the static IP configuration for this networks this is gonna be a rather one and I'm not

I use

to third and fourth quarter for 24 and 22 right.

I hope there is no problem about this depth and you can easily get this because that's really really

important portion of the static networking and it's time to take a look for the rather two very rather

too does is not directly connected.

Are

eleven

13 33 34 round 44 OK.

I completed this one to

and is time to take a look for the.

Our last trailer which is rather for four other four.

I need to use static ip reading statements for web

there is this this

is and

this okay.

There is no problem

and no I define that for which networks I'm going to use to the drawing.

Statements for example 4 rather one I'm going to get and the other one and say this guy Hey man hey

rather wrong.

If you have a packet which has a destination network idea of ten forty one thirty three that zero send

the packet to here

okay

I'm going to say the error thing for this network to

hey rather run if you have something that you don't know send the packet to this guy

and I'm going to get into the other two and I will say the to the Hey man if you have packets which

has a destination of this that works send the packet to

here

here I mean here I'm going to say rather for send the packets here and I'm going to say rather treat

to send the packets to.

So what I'm doing is I'm covering all the network as you see with the circle.

For example if rather one has for example let's say the P.C. one wants to communicate with P.C. two

packet loop counter other one rather one will check the destination address and we'll see that that's

twenty two that zero and we'll send the packet to here rather two will get this packet and rather two

is directly connected here as you know and we'll forward the package to a piece it would directly but

if piece one wants to communicate to it.

P.S. For rather two will also get the packet and send it to rather for and because of four other four

is directly connected to you that's gonna send the packet to the PCI for.

That's the logic behind this please pay attention that I will do this month to I could go to the rather

one and say that hey man if somebody wants to go to third three that zero sir packet Derek blue here

that would also work but for simplicity I'm just defining one way as a circle and I'm sending the packets

on that way you can also give it a try to sending for different points too there's no problem about

it.

All right.

Now it's time to go to the packet tracer again and I will make our configurations there that talk about

oh my god my seal is broken and it's lucky right now

OK and let's go enable comic my static growth config is like this as you can remember from our previous

slides it's IP rout IP out question mark I say is also that right.

The destination prefix okay for rather one my destination prefixes are

this is the destination that took subnet mask and

I'm going to write the forwarding Rather's address where I'm going to send the packet

OK Uno is now OK sorry sir so sorry anchor I'm configuring the rather one so I don't need to teach this

guy to eleven because it's directly connected so I need to start with this maybe

this through

44

24 and

22 here is my whole configuration force that craft

let's take a look to this portion I peer out

ten forty one twenty to zero and subnet mask off the destination network send the packet to

twelve that 2 which is rather 2 Alright

that's got 2 did rather 2 now in rather 2 I'm going to define eleven thirteen thirty three thirty four

and forty four as you remember because the other networks are directly connected and I don't need to

teach them two rather true I appear out

where I'm going to send the packets for mother two years

this one.

With star power as of the rather four

and I'm gonna configure this for a lower

13

33

34 and 40 for

OK cool.

Hey guys please warn me if I'm doing something wrong.

OK.

Enable com fake IP rout.

Come on man what's going on with you.

I out

it's going to be rather long this time

well 20 to 24.

And Fordham for awesome at least it looks awesome.

I hope so.

It's ours.

We are gonna check if there's something wrong or not.

In the last step enable

I peer out

send the packets to rather to interface right.

I'm going to also teach the is this guy

this network also

this network

Oh right.

It seems like everything is okay right now but I should wear.

If all my configurations are okay

I should pass these tests.

For example I should ping Pacer 2 from PS1 or I should ping pacing for from P.S. 3 but I'm going to

use to ping from P.S. 1 2.

P.S. 4 for example.

P.S. Once the IP address is 11 that 5

NPC four's IP is 44 that 5.

Let's go.

Please please work.

Alright guys.

No problem.

If we have some problem about the configuration we are gonna quickly trouble shoot it and I'm going

to show you how we troubles should step by step and we are gonna give you a quick solution for the problem

too.

Also but it's better that I prefer that it works and it to show you this one too.

I'm getting into the P.C. and I need to open a command prompt to use the pink command on a P.C..

Here is my comment.

Paying

then 41 for the 4.5 and under

please.

Please work please work please work please work.

Please work please work.

It's not working.

Not another.

Here is the band here.

It's not working

OK.

That's really cool for me

you will learn something more.

That means

it's working in a more we don't need to troubleshoot because it's hard working.

I don't know why pick a choice there.

Sometimes may do some weird things like this but our ping is working right now

so we don't need to travel ship but I'm gonna try to paint from this guy to here too and check what's

going on.

Let's go comment prom and let me check the IP address thirty three the five

and let's check it

it's working is working as we don't need to worry about our configuration right now because I can pick

the pieces from each other that means I'm verifying my configuration pretty cool pretty straightforward

there's no problem seriously on my network now everyone can reach everywhere it seems like I don't know

if there's a little problems with other devices but I don't think so.

But what if if we would have a problem and how we could trouble should it.

Let's take a look over at this if I couldn't paint from P.S. 1 2 P.S. 3 what I would do the first thing

and to check is the default.

Get me off the P.C. one.

Let's take a look to the default.

Get the Default Gateway is 10 41 11am 1 which is the IP address of the disk 0 0 interface of my routers.

And first I can take a look that if I have a connection to my default gateway or not by using pinging

the default gateway as you can see that there's no problem I can ping my default gateway if I couldn't

pin my default gateway if I wouldn't be able to pick my default pay I will check the geek.

0 0 interfaces IP configuration first OK the second step that I can loop that if package is reaching

here my gateway ping is successful and if I wouldn't still pink the P.C. for in here what I should check

is the IP address configuration of the interfaces and the static IP configurations of the by using

show IP.

Static common or I could also check this by using show run comment to as you can see that from the output

I have my static graphs for 22 okay 24.

Okay thirty two and thirty four and for the 440 rather one which means I have a static graph for my

destination that work that piece of for belongs to.

That's great.

That's cool.

And my configuration is working.

And it's time to check the third step.

And unless the

ballclub saves me that she run the show IP protocols and sure to Rudd commands and check the output

let's use the show IP protocols commented on rather run and

I can not see anything what's going on.

What's going on man.

We made something wrong.

No actually we didn't make something wrong.

Everything is right.

This is the output that I accept to see because I didn't use any dynamic routing protocols because of

I didn't use in dynamic crafting protocols.

Show IP protocols output is actually nothing because I used static writhing and the second come on this

show IP out

and as you can see that I had directly connect that interfaces automatically appearing on my rather

and the local interface of the rather is appearing automatically too also.

And these lines are appearing after the configuration of the static rather that we made on our previous

steps.
