‫And now is the moment you've all been waiting for.
‫It's time to build our network in G.A. three.
‫So I'm in my host machine and you don't see the genius three, it's closed at the moment, so I'll go
‫to the applications menu and click the giant S3 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, 37, 25.
‫That's what I imported a few lectures before.
‫So I'll drag it and drop it in the workspace from the switches menu, dragon ether switch router that
‫we created before and drop it into the workspace.
‫Now go to the end devices and drag and drop of EPCs here, as are the end user computer simulations
‫of giant S3.
‫A 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 V-Bucks.
‫OK.
‫Now we have a router and either switch and two pieces in our network.
‫They all have their default names on top.
‫Given by the Genius 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 an IP block of one nine two eight one six eight one zero zero slash 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 V Land 20, which is in the IP block of one nine two eight one six eight
‫two zero zero 24.
‫Now click on the last icon on the device's toolbar to connect the devices.
‫Collect 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.
‫Quick 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 label soon, 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 nodes at once.
‫Now all the nodes are running.
‫So now's the time to create our network topology.
‫I'll create two villains and add the pieces to their villains.
‫First, we'll create the virtual lands, 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 villain 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 keywords directly.
‫If the key word is the only available option for that short form.
‫So, for example, I wrote the U.N. Space Day and hit the tab key, the key word is completed.
‫Database.
‫So that means that database is the only option here for A.
‫And as a result, if I type Velan Space D.A and hit enter here, I'd be in the villain database mode.
‫Right, so here we are in VLAN database mode to create Velan 10 type villain ID, number 10 name ID,
‫for example, I.T. or whatever you want.
‫I'll name it VLAN 10 and leave it at that.
‫Hit Enter and V. Land 10 is created.
‫So similarly, let's create VLAN 20 with the ID number 20.
‫Type exit to exit the VLAN database mode now as you exit.
‫The changes are applied.
‫So it's pretty cool.
‫OK, so let's go into the VLAN database mode again to check whether the VLANs were actually created.
‫So type show current.
‫And here are the villains we created a couple of seconds ago.
‫We went in with the ID number of 10.
‫And here's VLAN 20 with the ID number of 20.
‫So Typekit 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 villains?
‫The first command we type is Configure Terminal.
‫And as mentioned before, you can simply type C and F T to enter configuration mode.
‫Now we need to select the interface to configure.
‫Type II, A. Space F..
‫And Hit Tab.
‫F will be completed as fast Ethernet.
‫You see how that works.
‫So now we can write the identifier of the switchboard one slash two.
‫Alternatively, you can directly type F1 slash two as seen in the giant S3 workspace.
‫Now we are in the config mode of the interface.
‫F1 slash to 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 Tennessee 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.
‫Switch Port.
‫Mode Access, OK, well, right here, I want to show you, well, a tip, you can use a question mark
‫in any one of the commands.
‫If you've got a question mark after the mode, it says you can either use access or trunk here.
‫And Access Port can only have one villain configured on the interface.
‫It can carry traffic for only one villain.
‫Right?
‫A trunk port can have two or more villains configured on the interface that can carry traffic for several
‫villains simultaneously.
‫So Switch Port Access VLAN 20 goes right here.
‫No shut down and exit.
‫Great, so we've configured the interface is connected to the PC.
‫So now let's configure the port connected to the router.
‫IMT four interface F1 slash one to enter the config mode of that interface.
‫Switch port mode is trunk.
‫Wait a second.
‫And yes, the port has become a dot one trunk.
‫Now one queue is the well known name of the 8.2.1 queue, which is the networking standard that supports
‫virtual lance or villains on a trivially eight o 2.3 Ethernet network.
‫Now type switch port trunk encapsulation dot one CU.
‫No, to shut down and exit type, exit again to exit the config mode completely.
‫Ben Typekit, you are 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 conf tea and hit enter.
‫So the only interface of our router is fast Ethernet zero zero, so type interface after the zero zero.
‫No IP address.
‫No, shut down 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 slash 0.1, where one
‫identifies the sub interface, right?
‫Type encapsulation that one Q and a question mark to see the options like that here.
‫Velan ID is one of the options.
‫So type encapsulation dot one Q 10 Now Type IP address one nine two eight one six eight eight one zero
‫eight one 255.255.255.0 and press enter.
‫One nine two two eight one six eight one zero one is the IP address of the router for this villain,
‫and 255.255.255.0 is a subnet mask of the network.
‫So the IP block of the VLAN 10 will be one nine two eight one six eight one zero zero 24.
‫No, to shut down and exit.
‫And here we are back in the Configure Terminal mode.
‫So now will apply the same sub config for VLAN 20 type interface have zero slash 0.2 this time.
‫Encapsulation that one Q and the VLAN ID 20.
‫So let's use the one nine two one six eight two zero zero slash 24 IP block for this villain.
‫Said HAPE IP address 192.168.0.1
‫255.255.255.0.
‫And no shutdown and exit.
‫Now, exit again to exit the configure terminal mode as well, and type W are to make the configurations
‫persistent.
‫See what I mean, it's it's 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 right click on the PC and select console.
‫If you place a question mark and press enter, you'll see all the available commands and VPC console.
‫So as I mentioned before, this is an end user computer simulation of Gianna's 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, IP Command is used to configure the IP settings of the VPC.
‫And here you can show or use the shortcut as each, 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, BBC has no IP address at the moment.
‫So type IP and a question mark.
‫You'll see the options of the IB command.
‫And as you can see here, you'll 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.
‫IP one nine two eight one six eight eight one zero eight to slash 24 to identify the subnet mask and
‫the Gateway is one nine two two one six eight 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 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 IP one nine two one six eight two zero dot to slash 24.
‫192.168.0.1 and hit enter.
‫Ping, 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 ping PC to.
‫You should be able to see the reply packets, just like these ones are now paying PC one from PC two.
‫And everything looks perfect on my side.
‫What about you?
‫Right as rain, right?
‫Excellent.
‫So let's move on.
