Okay so let's start with the Rhonda Archer the moment on the router.

No IP addresses are configured.

So the first thing we need to do is go on to the gigabit 0 0 0 interface and no shut at

and then we need to create sub interfaces.

So notice I'm going to choose dot 1 as the sub interface for VLAN 1.

I'm going to specify an encapsulation of DOT 1 q using VLAN 1 as the native villain the management villain

is typically your on tag the villain which by default is villain 1.

I can now configure the IP address of the router the lost IP address in subnet 10 1 1 0 slash 24 is

10 dot 1 to 1 2 5 4 so do show run shows us the configuration of the first sub interface.

We now need to configure the second sub interface which is VLAN 10.

You don't have to use the same numbers as the villain number that just makes it easier.

So I'm going to specify V Line 10.

This is not the native v LAN IP addresses tendered 1 to 10 to 2 5 4.

So again show run

there is the configuration of airline 10 and then I need to create a third sub interface for v land

20 encapsulation is going to be top 1 q V Line 20 IP address is gonna be 10 dot wonder 20 dot 2 5 4

slash 24.

So again there's the configuration of the physical interface reveal and one sub interface Vila in terms

of interface VLAN 20 sub interface.

The next thing we need to do is configure the switch so on the switch show IP interface brief no IP

addresses are configured Vila and one is administratively down at the moment so Conti interface of Ilan

one no shut IP address tendered one that 1 2 5 3 slash 24 we've been told to only configure an IP address

in V Line 1 so let's confirm that the switch can paying the router it can but that's not entirely correct

yet we still need to configure this interface as a drunk Port Vila and one will work because it's the

native v LAN but other v lines will not work so switch port mode trunk we need to specify an encapsulation

so switch port trunk encapsulation dot one key

and now we can make the port a trunk port.

So those two commands are required.

Interface went down it's now come up again.

So show run.

They are the two commands and gigabit.

1 0 1.

Can we stop paying for the router at the moment it's not working but now it is.

It just took a while to notice the pings have now succeeded.

Packet traces showing green on the link.

So that looks good.

We now need to configure VLAN 10 and VLAN 20.

And we need to put our pieces into those villains.

So our two pieces are connected to ports 1 0 2 and 1 0 3.

So interface gigabit.

1 0 2 switch port mode access switch port access VLAN 10.

In this case interface gigabit.

1 0 3 switch port mode access because it's a P.C. switch port access VLAN 20 so show run.

What have we configured gigabit 1 0 1 is a trunk port gigabit 1 0 2 and 1 0 3 or access ports 1 0 2

is in VLAN 10 1 0 3 is in V land 20 so we can use commands such as Show interface gigabit 1 0 1 switch

port to verify the configuration of an interface.

So this command shows us that gigabit.

1 0 1 is configured as a trunk port and is operating as a trunk port.

The encapsulation used is not one Q access v LAN is v lan 1 if we look at Interface gigabit.

1 0 2 to this port is an access port in VLAN 10 look at 1 0 3 this port is an access port in VLAN 20

so that looks good.

We've configured the V lands on the switch we've configured the link between the rod and switch.

Now we need to confirm that the pieces can ping each other.

So on PCI 1 we've been told to configure the PSC with a static IP address the default gateway will be

the router on the P.C. so I'll set both the default gateway and DNS to the router the IP address will

be tendered one dot tendered one subnet mask is going to be a slash 24 subnet mask so on the command

prompt IP config we can see the configuration of the P.C. that's correct.

Per our instructions default gateway is wrong I should make that ten.

Always good to verify.

So do that again.

That looks better can we paying the default gateway.

Yes we can.

So that's good to something similar on P.C. to default gateway will be tendered one to twenty two to

five for DNS server will be tendered one to twenty two five for IP address of the P.C. will be tendered

one dot twenty two to subnet mask will be a slash 24 subnet mosque open up a command prompt IP config

that looks good can we paying

the router.

Yes we can.

Can we ping.

P.S. 1 so paying tendered wonder tender 1.

Yes we can CPC to is able to ping P.S. 1 and can P.S. 1 paying P.S. 2 Yes it can.

So we've successfully configured this network with V lands and interval and routing using a router on

a stick.

So now let's do the extra work for credits.

How do we get everyone to talk to everyone on the switch.

We need to configure an IP default gateway

pointing to the router in the same subnet as the switch to paying 10 1 1 2 5 4.

That works.

Can the switch ping the first P.S. after the moment it looks like it can't can it ping the second P.C..

At the moment it looks like it can't.

When you use IP default gateway you need to ensure that routing is disabled.

In this example writing is enabled.

So we going to say no IP routing because this is a layer to switch and not a layer 3 switch and that

should allow us to ping the pieces which it does.

So this is the lesson.

If you have IP routing enabled you don't use the default gateway command.

So as soon as I enable IP riding on the switch the IP default gateway command is ignored by the switch

and the switch can't ping the pieces.

Now typically on switches the default behavior is to have IP riding disabled.

So this is the default behavior in this lab.

However it was turned on.

So we need to verify that it's off so that we can ping the pieces using the IP default gateway command.

So can P.S. 1 ping the switch paying tendered 1 at 1 2 5 3.

Yes it can can P.C. to ping the switch

yes it can.

So we successfully configured this network per our instructions.

Don't forget to save your configurations on your devices.

In the exam you may have to use the command copy running config startup config.

Here I I'm simply using the old command W R but I would suggest in the exam that when you finished save

your configurations I hope you found this video useful.
