Hello everybody.
That's now configuration door.
This is gonna be our first configuration lab and I'm feeling really really excited.
We have nine steps to accomplish and we'll simulate these topology in the Cisco Packet Tracer application
build a little step by step and in the first step our lab says that cool video router host names.
And first let's set this lap in the packet tracer then configure the host names as shown in the figure
I'm switching to the packet tracer
I need to take two routers.
But first I want to talk something about Cisco pick up traces.
This is a simulation program that you can use to assimilate your devices.
Cisco devices and you can make some configuration you can do any topology that you want.
Sometimes this truly may not be supporting sent commands but that's no problem.
That's really supporting most of the comments in the CCMA XM so let's take a look to the my topology.
I have.
Sorry I have two brothers and I can choose the network devices from this step.
As you know as you can see that we have network devices tap and to remove the
taskbar too.
Sorry.
Now let's put two others in here.
I mean need to zoom
that you can see better
we are two others and we need to connect these two others with our cable
and taking the cable and connecting the brothers from the Gigabit Ethernet 0 0 parts.
Let's see that.
If I say something if I have something more formal to push you all know is okay.
I connect to my right to say to each other.
Now it's time to configure the host names.
I'm going to configure hostname Madrid and I'm going to configure hostname Miami for a Rather's I'm
going back to pick up Troy sir and to configure otherwise I just click on the rather and I'm using the
CLIA tap.
Welcome to CLIA.
Guys as you can see that I'm in the command prompt of the router and if Cisco others are asking something
like that when they first reboot when they first put continue with configuration dialog yes or no please
answer yes or no.
If you choose yes in the step you receive a configuration dialog and rather asks you many questions
if you want to come.
Convert your host name you want.
Would you like to configure IP address.
Would you like to use some routing BLOCK Also Alabama etc..
I don't really recommend that.
We're gonna use manual configuration way.
So I don't want to continue with the configuration dialog.
I'll never use this.
Okay.
I selected No.
And it's time to make some configuration as you'll remember from our sections.
We're in the what month use in what this is the user exact mock if I want to make some configuration
on the rather I need to switch to the conflict mode.
But before I go to the conflict mode I need to go to enable mode first.
So I am typing enable all right
this sign.
Switch to the pound sign as you see.
Which means that I'm in enable mode for now and let's
use a question mark first.
The question marks show the com list of the comments that I can use in the privileged exec mouth.
As you can see that we have some comments that I can use in here but what I need to go well.
But what I need to do is to go to conflict Matt I need to type config terminal to get to the configuration
what.
That's okay.
Everything is fine.
But first before configuring hostname I want to show you which commands that I can use in the conflict
mode too.
So question mark as you can see that I can configure Triple A I can configure access lists I can configure
hostname I can configure global IP configuration key license so too much things that I can configure
as you can see but what I'm going to do is to configure the hostname that the LEP wants me for all to
for you to host them.
My comment is hostname.
That's it.
Hostname it was moderate for.
And that's it.
Enter as soon as I enter.
As you can see the hostname of the rather switched to Madrid from right.
OK let's configure this rather to now.
I will never want you in a row again.
First
no I need to switch to the conflict mode
now it's time to configure Miami hostname Miami and there.
And as you can't see that name switch to Miami as soon as I click the I push the under Oh right.
Step 1 are accomplished
step to configure enabled password for Madrid and enable secret password for Miami and passwords are
same network key L1 2 3 okay to read it remember how to configure the
you will remember if you don't remember even now up.
Sorry sorry sorry sorry.
I am in Madrid and I'm going to configure and enable password now please pay attention that I'm still
in the config mode
if I want to go to the privileged exit what I need to use exit
but I need to configure in the configuration mode so let's do it the command is enabled password to
create an enable password on our rather enable password and let's see a question mark was saying we
can define a level two also but I'm not going to do it ups I'm sorry Ma my keyboard is making me crazy
sometimes I'm just going to set the password now enable password networking so 1 2 3 that's it and I'm
going to
configure it and enables password on Miami enable password not password okay.
Please keep in mind that when I try to configure enable password I'm using enabled password command
but if I want to configure enabled secret I'm using enabled secret command.
You can easily show that
you can easily see that using the question mark again as you can see that after enable we have two options
that we can use the password or the secret now we are going to use secret and my password is the same
network e-mail went to three other.
All right.
They are going great.
Step two accomplished
in the step three.
We need to configure the talent for both truthers and passwords will be remote One two three this time
okay.
Let's go in to it.
Go figure.
I want to configure the I want to configure the models first.
My God why always Miami I want to go to met with okay.
I'm mad.
Now
if you want to configure the town at on their rather you first go to live under the Mutual two lines.
Line
let's see what I can use where your lines are read to me.
Why.
As you can see it line meaty y 0 4
I'm using log in
and I need to set a password password my password is remote 1 2 3 and download again.
Okay as you can see that ISIS giving me a warning first log and disabled on 5 lines as I told you in
the sections and the password is set and then I set the password.
That's gonna be enabled but it's okay that I type to log in again to okay.
Let's go to the Miami now.
I'm in Miami who is not typing Yeah it's okay.
Line 0 4
password remote 1 3 again why didn't the type password removed.
1 2 3
Logan and that's it.
We are going pretty cool and we accomplished the third step to now it's time to check our configuration
with show run command.
Use short run command and check the configuration.
I'm not a check the configuration of matter it as you can see I'm in the cornfield line mode right now.
That's a specific mode if I want to run the show commands.
I need to go to the privileged mode.
I can go with typing exit and exit with two times and I can go to the privileged most privileged exit
mode.
But I can also go to the privileged mode using and in the specific mode as you can see that just type
and and you're in the privileged exit right now and let's type the show run comment that our lap wants
us from.
But I'm going to show you something else right now.
I typed show run but if I want to make sure that and if I want to see the complete form of the comment
I need to press to tap and I'm typing tap.
Brent No I pushed the tab button and as you can see that I just completed the comment the WHO version
of the command this show running config arrived and I just entered
as you can see that I can see that I configured the hostname in this rather which name is Madrid I said
and enabled password network here one two three
and these are the default configurations and I configure the Telnet please keep in mind that you need
a password is in plain text in magic drafters and let's go to the Miami now.
I am in Miami
in Miami.
I will go to the privileged exec with double exit exit exit
show.
Run
and you
the first thing I need to pay attention is I'm seeing something special in here as you can see that
enables secret password is not in plain text.
It's hashed as you see
so that's a secure method.
As I told you before before using enabled secret password is a secure
as you can see that I also configured that hostname and
I also configure the telnet
and let's check that if my enabled secret password is working or not enable secret password is being
used when I try to switch from user mode to the privileged exit mode I am a user mode now and type enable
again under yeah it's asking me password right now as you can see that I'm typing my password network
a 1 2 THREE
AND YES THAT'S through and I am in privileged exact right now
alright right everything is going fine for me now and our fifth step is saying me and create all passwords
in show run output how we can do it.
To accomplish this I need I need to go to the moderate which my password is not encrypted
I want to show you again
which show room as you can see that my enable password is in clear text and if somebody gets my show
running config he or she can easily display my enable password which is now good okay so I need to encrypt
this one too and I have two options to accomplish this.
First I can use and enable secret password but I have in other method that you can remember from our
sessions and that's it
I had to go to the configuration mode and I need to type.
So is
I'm using a question mark and I want to show you that if you if you see something and that's it and
create system passwords as you can see that the command is service password encryption and there's as
soon as I type this router encrypts the WHO passwords in the short run LSC see that exist and show grown
who it was network E L one two three.
Just one minute before and what is it right now.
As you can see that it was encrypted and I can't understand anything.
As I look at this I can understand that that's network.
AOL one two three men
Oh right.
Pretty cool.
We have done this too.
Now in the six step choose proper IP addresses for geek 0 0 interfaces on bulk rollers and configure
them and let's first choose proper IP addresses for the interfaces as you can see that the network idea
in here between Mather than Miami raptors are
this one my network idea is ten forty one thirty eight that zero slash 24 which means that I can use
the address space
from one to
two hundred and fifty four please keep in mind that I can't use the last IP address because this address
is being used for the broadcast traffic
so I'm going to configure the dick 0 0 interface of magic that
and here is going to be
that to okay.
As I told you in here I can choose whether I want in this range
saw I choose this one then let's configure them
I'm going to configure the geek 0 0 interfaces and let's go I need to go figure I need to go to configuration
mode and I need to go to the interface mode.
Because I'm gonna configure ran in the race.
Okay.
Pretty straightforward interface Jaeger with the turn at 0 0.
Enter
and I'm gonna configure my pelvis IP address
that one and my son.
The mask is slash 24 which means
2 5 5 2 4 5 2 4 5 0 and I hit the end of
but what I need to tell you in here please never forget to use a command when you configure an interface
Cisco in Cisco devises
interfaces are in shut down more difficultly so human to activate the interface using the no shut down
command as soon as I enter it as you can see that I see this log message in here interface Gigabit Ethernet
zero zero change state to up it was down before default as I told you but as soon as I type nor shut
down its up anymore.
Alright let's go to the Miami now
where is that thing I am in Miami and making the same configuration in here
interface gigabit 0 0 an IP address that 2 2 5 5 2 5 5 2 4 5 0 enter and that's it.
No man that's not Ed because you didn't type.
No shut down OK no shut
and as you can see that in the face change take that up and also the land protocol on the interface
Jaeger.
Zero zero chance change up which means that Miami is saying that oh my God there's somebody on my Gigabit
Ethernet 0 0 port and okay I'm sure I'm seeing that guy not now.
And as you can see that here was read before and it's green in a more
that means this link is operate operating all at the ozone layer by all right.
Pretty cool huh.
That's the key to what this guy wants me down from this guy wants so much think ping Miami's in the
face for Matt.
I will go to Madrid and I'll issue a peak comment to pink here what does pink
if I want to check that if I have reachable it lead to somewhere I can use pink comment
am testing that if I can send the packet to here and if the packet is coming back to me right now.
Please keep in mind that verification commands work on the privileged exit.
More like show comments.
So I need to go to propose exactly again.
And my comment is just paying nothing else.
Pink.
Pink Oh no no it was too and I just hit 10 of
and yes as you can see that I could pink I didn't get the request time up message and my pink was successful.
Step 7.
XXX
in the 8 step it's shit.
It's saying ask to use show run command and check the configuration for the last time okay.
And in the last step.
It's saying as to say ah configurations on both Rather's let's save the configuration first.
I'm in Madrid's remember that if I want to save the configuration my command is right.
Memory which I use in the privileged exit mode again right.
Memory under it's okay and
right memory it's not okay because I'm not improved.
Exec Mom.
Oh I'm sorry.
And right.
Memory.
That's it.
I saved all of my conflagration right now.
Even if I reboot this device right now my configuration will be with me no problem right now.
OK now it's time to take a look to the show right.
We are in Miami and he should show run.
In Miami we have enabled secret password as you can see
and we have an IP address attached to the interface.
0 0 0
and we have our telnet configuration and my password is in plain text and that's it
and look at it is show run in here to we have hostname we have encrypted password in here.
Even if I use enabled password because I used service password encryption command in here.
We have IP address configured under 0 0
and as you can see that because of I use service password encryption command my telnet password was
encrypted too because of I didn't use the service password encryption in Miami it was in plain text
but in Madrid it was encrypted to
right.
We accomplished all these steps we made our first configuration and that was a really great session.
Thanks were weaving and see later in the next lab.
