And now is the moment you've all been waiting for.
It's time to build our network in Janna's three.
So I'm in my host machine and you don't see the Ginés three, it's closed at the moment, so I'll go
to the applications menu and click the Jeunesse three icon to run it.
So let's create a new project or you can use the project that we created before.
Expand routers from the devices to bar, as you see installed items is selected from a combo box above.
The only router available is C thirty seven, twenty five.
That's what I imported a few lectures before.
So I'll drag it and drop it into the workspace from the switches menu Dragon Ether's, which router
that we created before and drop it into the workspace.
Now go to your own devices and drag and drop of books here, books are the end user computer simulations
of Genesis three.
They're very lightweight and have a very restricted ability, but it'll be enough to test the network
configurations.
And I'll just add a second VBC, yes, OK.
Now we have a router and either switch and two PCs in our network, they all have their default names
on top given by the G.A. three app.
So now I want to design a network and label the devices accordingly.
Click the labels icon on the toolbar and put a label under the PC one, this PC will be in IP block
of one nine two one six eight eight one zero zero 24.
Let's say it's the VLAN 10.
Now, to create a new label, you can right click on an existing one and select duplicate.
Right, click the label again and select text, edit to edit the text, so let's put the second PC into
Vilan 20, which is in the IP block of one nine two to one six eight two zero zero twenty four.
Now click on the last icon on the Devices toolbar to connect the devices.
Click the router, select the port, you want to connect, and then select the switch and select the
port of the switch again.
I connect the fast Ethernet zero zero port of the router with the fast Ethernet one one of the switch.
Good, so now connect the PC one with this switch.
Click, switch, select fast Ethernet one, two, and click PC one.
And it already has a single network interface, Ethernet zero.
Now, do the same with his second PC, and you supported the switch, for example, fast Ethernet one
10.
We connected all the nodes on the workspace, so now we can click the Connect icon to disable the connect
mode.
And in the toolbar, we have a button named Show Hide Interface labels, if you click it when the labels
are hidden, you'll see the labels of each interface connect.
F stands for fast Ethernet and E stands for the Ethernet.
And you can move the labels as you wish.
Now, let's start the note.
We can start them one by one by right clicking on them and selecting start from the menu or from the
toolbar, click the Green Triangle to start all the notes at once.
Now all the nodes are running.
So now's the time to create our network topology.
I'll create two villans and add the PC's to their Vlad's.
First, we'll create the virtual lens right.
Click on the switch and click console.
Good.
Welcome to the command line interface of a Cisco either switch look familiar?
So press enter to get started.
Type Vilan database and go there.
You can use the tab key to complete the key words in this console.
So instead, you can use the short form of the key words directly.
If the key word is the only available option for that short form.
So, for example, I wrote Vilan Space Day and hit the tab key, the key word is completed.
Database.
So that means that database is the only option here for d.E.A.
And as a result, if I type villans based dieser and hit Enter here, I'd be in the VLAN database mode.
Right, so here we are in vivants database mode to create Vilan 10 type VLAN, ID, number 10 name ID,
for example.
It are whatever you want.
I'll name it Vilan 10 and leave it at that hit.
Enter and Vilan 10 is created.
So similarly, let's create Verlan 20 with the ID number 20.
Type exit to exit the VLAN database mode now as you exit, the changes are applied.
So that's pretty cool.
OK, so let's go into the van database mode again to check whether the villains were actually created.
So type show current.
And here are the villains we created a couple of seconds ago.
You intend with the ID number of 10 and here's VLAN 20 with the ID number of 20.
So tiebacks it again and we're on the route of the switch console.
So now is it time to configure interfaces and add the PCs to their villans?
The first command we type is configure terminal.
And as mentioned before, you can simply type conf T to a configuration mode.
Now we need to select the interface to configure.
Type A. Space F and hit tab.
F will be completed as fast, either net, you see how that works.
So now we can write the identifier of the switchboard one, two.
Alternatively, you can directly type F one, slash two as seen in the GNC three workspace.
Now we are in the config mode of the interface F one two, which just happens to be the port we connected
to the PC one.
Now, to identify the mode of the port type switch port mode access first.
Then to assign the port to the VLAN 10 type switch port access VLAN 10.
Where 10 is the ID number of Valentin.
No, to shut down and exit.
We exit from the ports config mode, but we are still in the terminal configuration mode, so while
we're here, let's configure the other port, which is connected to PC to interface fast Ethernet one,
slash 10.
Switchboard Modak says, OK, well, right here, I want to show you that, well, a tip you can use
a question mark in any one of the commands.
If you've got a question mark after the code, it says you can either use access or trunked here.
An access port can only have one VLAN configured on the interface, it can carry traffic for only one
VLAN, right.
A trunk port can have two or more villans configured on the interface that can carry traffic for several
VLAN simultaneously.
So Switchboard Access Vilan 20 goes right here.
No shutdown and exit.
Great, so we've configured the interfaces connected to the PC, so now let's configure the port connected
to the router.
IMT for interface, if one is one to enter the config mode of that interface.
Switchboard mode is trunk.
Wait a second.
And yes, the port has become a dot, one queue drunk, not one queue is a well-known name of the arrow
to dot one queue, which is the networking standard that supports virtual land or villans on a I Travelle
Aido three Ethernet network now type switch port trunk encapsulation dot one queue.
No, to shut down and exit type exit again, to exit the config mode completely, then type W.R to make
the configurations persistent.
Excellent.
Now let's configure the router.
Right, click on the router and select console.
The ports are being initialized now.
OK, entering into the config mode is the same type config terminal or simply can't t and hit enter.
So the only interface of our router is fast Ethernet zero zero.
So type interface after zero zero.
No IP address.
No shutdown and look at that, the port is up right now.
So hit exit and we'll exit from the interface for now.
So now we're ready to configure the sub interfaces and the settings of the villains are decided here.
To one of the sub interface configuration type interface, fast Ethernet zero zero dot one where one
identifies the sub interface, right.
Type encapsulation that one.
Q And a question mark to see the options like that here.
VLAN ID is one of the options.
So type encapsulation dot one Q ten now type IP address one nine two one six eight eight one zero dot
one two five 5.2 five 5.2 five 5.0 and press enter.
One nine two, not one six eight one zero one is the IP address of the router for this VLAN and two
five five dot to five 5.2 five 5.0 is a subnet mask of the network.
So the IP block of the VLAN 10 will be one nine two, not one six eight eight one zero zero 24.
No, to shut down and exit.
And here we are back in the configured terminal mode.
So now will apply the same sub config for Vilan 20 type interface at zero zero two this time.
Encapsulation.
One Q and the van ID 20, so let's use the one nine two one six eight eight two zero zero twenty four
IP block for this VLAN.
So hype IP address one nine two one six eight nine two zero one two five five dot 255 got 255, not
5.0.
And no shutdown and exit.
Now exit again to exit the configured terminal mode as well and Type W.R to make the configurations
persistent.
See what I mean, that's that's a quite a process, but I'm glad you're hanging in there because we
haven't even got to the fun stuff yet.
Now, is it time to configure the network interfaces of the PCs?
So I click on the PC and select console.
If you place a question mark and press enter, you'll see all the available commands in VPC console.
So as I mentioned before, this is an end user computer simulation of Ginés three.
But not to worry, it's enough to test the configurations of the networks that we created earlier.
And as you can see here, IPE command is used to configure the IP settings of the VPC.
And here you can show or use the shortcut, S.H., and that's going to print the information about the
VPC so type show IP to see the current IP settings.
And as you can see here, VPC has no IP address at the moment.
So type IP and a question mark.
You'll see the options of the IP command.
And as you can see here, you will be able to assign an IP address using this command and an example
is given right there to help as well.
So let's assign an IP address for the VPC.
IPI one nine two one six eight one zero two.
Twenty four to identify the subnet mask and the gateway is one nine two one six eight one zero one.
Perfect.
It's our router.
So when you press enter, it checks to see if there's any duplication and if everything's OK.
It shows a summary just like this one assigned to IP address, subnet mask and Gateway.
So now we can ping the router to check the configuration perfect.
See, this is where we get all the answers.
Now let's configure the other VPC because that one is working perfectly just the way we wanted it to.
The steps are exactly the same.
Right, click and over the console.
Type i.p one nine two one six eight two zero two twenty four one nine two one six eight two zero one
and hit enter.
Paying the router to check the config.
And here are the answers, all the answers you've ever been looking for, right?
So go to PC one and being PC to.
You should be able to see the reply packets just like these ones and now being PC one from PC to and
everything looks perfect on my side.
What about you?
Right as rain.
Right.
Excellent.
So let's move on.
