All language subtitles for 7. Inter VLAN Routing

In the section we're going to talk about it and to learn writing.

Every line everywhere you look Clarion network defines air broadcast domain and pro-white is in management.

Also provides isolation as you know and the different religions can not communicate each other without

a layer 3D way such as a rather firewall or Layer 3 capability of switch by using interval and routing.

You can establish communication between different Whelan's with a layer 3 device.

Popular method of the entire Willam routing are rather on a stick and the layer 3 switching Let's go

ahead with the rudder on stake rather honest thig is a term frik currently used to describe as set up

that consists of a rudder and switching connectors using one Internet link configured as and that one

kid trunk link in this method the which is configured with multiple Whelan's and the rather performs

all routing but when the different networks and will last for this purpose you create some interfaces

configured with that one too.

So they can interact for different per Villon on the rudder as you can see on the rudder a

we have the physical interface connected to our switch which is Jake's 0 zero.

This is the physical interface.

But what that doing in this method Protheroe stick method is I'm creating 1 2 and 3 sub interfaces for

the Z example.

Supro but the communication between these three different.

Well that's OK.

Let's go ahead how we can configure air rather s take on the switch site.

What are you going to do is own data on only related to interfaces.

I'm assigning my Whelan's to the interfaces as you can see for example interface Westlands 0 for real

want to really understand and the five will be blowing them to 20 and the other guy six will be longing

to real 30.

Then there 0 1 will they call regard as that throwing poor because that's going to carry the will and

10 20 and the plus willen 30

but I'm going to configure on the other side is for rather a I'm going to create some sub interface

can see to create a soap interface.

The command is interface Dig's 0 1 the physical interface that's some interfaces name.

This is the sub interface.

The whole thing is the Savander phrase gig 0 1 that 10 gigs or one that 20 gigs or that what one does

40 OK I'm terminating to willen 10 women 20 and beyond 30 in here as you can see but I could do this

thing also gig 0 1.

That may be 15 but if you use again encapsulation that went to 10 I will be Temi Timmothy terminating

will Hanigan in here.

OK this number is arbitrary.

But for simplicity we are using the real number as the sub interface name.

This link we are going to focus we need to focus on for terminating the line is actually the encapsulation

that one key commands.

All right we're getting into the sub interface mode by typing Digg 0 1 the 10 in here then we're typing

the encapsulation and encapsulation mode will be up to 1.

And then the real number OK.

That means we are terminating we are terminating the we learn 10 to 20 and 30 for it's interface OK.

Then the last thing we're doing in here is we are assigning an IP address for age 7.

There is for example 4 gigs 0 1 that one up 10 I'm assigning 10:41 10.

That 1 4 gig 0 1 that 20 I'm assigning 10 for 120 that one and 30 or one for the other guy.

OK we're done it to call for you on the client side.

For example PC 1 PC 2 and PC 3 I need to code every year.

This some interface IP addresses as the default gateway of these clients.

And for example if PC one wants to communicate with PC to see if they have different network IDs the

packet will be forwarded to the default gateway which is 10 to 1.

Which is this interface then will be forwarded forwarded to Jiggs 0 1 the 27 interface and packet will

come to PC to to Wayfinder rather in sync configuration.

First we can ping close to us from each other.

For example we can think we PC one from PC to and we can check air show running cool freq output and

we can check the Step-By-Step configuration or we can take just to some interface configuration by typing

show around interface and the sub interface name.

Or we can check the show interfaces trying on the switch and blue and we can see if the link is through

with it if the link is operating as a trunk or not.

Let's go ahead with layer 3 swaging now.

Guys traditional network Swades operate at least two of the oversight module one network brothers operate

at Layer 3 as you know they layer three which is a specialized specialized hardware do us with the capabilities

for this purpose.

We need to configure interfaces called SBI switch where chool interface for each line and put an IP

address on it.

This I tell this can be used for computers as their default gateway.

Let's take a look to the leader three switching configuration right now.

First we need to start by typing the IP routing command on our multi-layer switch.

If you forget this your switch won't build air routing table.

Then we create the SBA switch ritual interfaces and define the proper IP addresses to ask the eyes and

that IP addresses are called for your as the default gateway of the class.

For example in here are defining an interface real and true in it this is an SBA then we are defining

an interface we are 30.

This is as all saw and we are defining interest we allow for it.

This is all the rest why.

OK.

We are defining the as you realize then we are assigning IP addresses in here as you can see each as

we will have a different IP address and these IP addresses will be called for you as the default gateways

on the client server you can see OK that's the same logic with the rudder on the stake.

But the difference is the difference is we are creating the x rays instead of the sub interfaces.
