Let's start with the access switches switch 3 and switch 4 on not going to do in TV land rotting.
These are going to be configured as a layer 2 switches.
So I should change the symbol of the switches to be simple ethernet switches.
They are simply going to be late to switches that provide connectivity to the rest of the network.
So change the symbol of both the switches.
They will have one IP address configured and that IP address is only used for management purposes.
So the IP address configured on the switches is only to allow telnet or S-sh to the switches for management
purposes.
They're not going to do any kind of routing user devices shouldn't typically be able to ping teleco
S-sh to the Access switches so on switch three conforte interface a villain one this is known as a switched
a virtual interface or vi type do show IP interface brief on the switch and scroll down you can see
that the FBI has been raided but it was shut down previously when I did the command show interface brief
the FBI interface was not created.
So by using the command interface villaine one I've created this switch of virtual interface.
So IP address tendered one to 100 top three subnet mask is going to be slashed 24 and I need to know
shut the VI because by default it's administratively down top and ping before I do a ping show IP interface.
Grief notice the interface is now up.
So I should be able to ping myself ten one one hundred three and I can still save that config and then
I'll go to search for once again show IP interface brief
No VI currently exists only the physical interfaces interface Villon one IP address.
In this example it will be 10 to one 104.
So IP address 10 1 to 100 for slice 24 mosque no shut it save the conflict interface villaine one has
come up.
As you can see over there
paying tandoor one to one hundred or three Ping's succeeds the first ping failed because the switch
had to do an app for the Mac address of switch 3 but notice switch 4.
He's now able to ping switch three.
And by the same token switch three is now able to ping switch four.
So that's a good sign because it means our links are up in a moment I'll discuss CGP and LDP will Siskin
discovery protocol and Nicolay discovery protocol and show you how to check the connections between
switches on switch one and switch to.
We need to configure multiple IP addresses one per line because of these switches we'll be doing interval
and routing.
So switch one show IP interface brief at the moment no feelings are configured.
So interface VLAN 1 IP address 10 1 100 1 2 4 5 2 4 5 0 no shut interfaces and
10 IP address 10 1 to one slash twenty four no shut interface villain 20 or interface violent 20 rather
IP address change at $1.20 one slash twenty four.
No shut controls or controls that show IP interface brief at the moment only villain one is up and 10
and violent 20 or down.
And that's because we don't have any interfaces configured in a violent 10 or violent 20.
I'm going to show you in a moment how to explicitly configure these Portus trunk ports and then we should
see that those files come up.
Switch to show IP interface.
Brief no is Fiore's interface VI interface the line 1 IP address 10 dot one dot 100 to 24.
No shut interface the plan 10 IP address 10 to 1 to 10 to 24.
No shut in to face violent 20 IP address tendered one to twenty to 24 no shut and show IP interface.
Brief once again the line one is up.
Vigeland ten and violent 20 on down.
And that's once again because when we use the command show interface gigabit 00 switch port as an example.
You'll notice that the port is configured for villaine one but no other villains have been explicitly
configured across this port.
The access villanies villaine one by default.
If DTP or dynamic trunk protocol doesn't negotiate with the other side to form a trunk trunking in native
land is villaine one by default.
So we only have interface Villon one up the other interfaces are down but as that time management villaine
we were OK to use that for testing so I can switch to ping switch one.
Yes it can should be able to ping itself which it can.
What about switch 3 which it can.
And what about switch for yes it can.
So we have IP connectivity in our network.
The switches can ping each other.
Let's do another test on which one can ping itself.
Yes can Kennett's pings switch to yes it can switch three yes it can switch.
Yes it can and I'll save the config.
So we've configured IP addresses on the switches can the switches ping router 3 which is in the management
plan.
So Sichuan once again paying 10 1 100 2 5 3 2 5 3 rather yes it can.
So which one can ping this IP address of router 3.
Now these routers acting as PCs are going to be put in two separate villans so will do the pinging when
we configure those devices in a separate Villon.
At the moment we haven't got violent when configured properly in the network so we can test connectivity
between our PCs and the switches.
