1

00:00:00,257  -->  00:00:07,082
In the previous video, we already talk about
multi layer switch or layer 3 switch.

2

00:00:07,770  -->  00:00:15,746
Next in this video, we are going to learn
how to configure SVI or switch virtual interface,

3

00:00:16,396  -->  00:00:22,234
which is connecting between pc in the different
vlan using multi layer switch.

4

00:00:23,063  -->  00:00:25,222
Okay let’s just start.

5

00:00:25,872  -->  00:00:28,538
Here let’s remove the router.

6

00:00:31,717  -->  00:00:39,640
Okay now we don’t have a router anymore,
and if you remember, we also already configure

7

00:00:39,640  -->  00:00:42,192
dhcp server in the router.

8

00:00:42,957  -->  00:00:47,874
So now the pc can not get an ip address automatically
anymore.

9

00:00:48,244  -->  00:00:49,420
Let’s try it.

10

00:00:50,389  -->  00:00:54,125
Here let’s click static and dhcp again.

11

00:00:56,866  -->  00:00:58,384
Okay here failed.

12

00:00:58,499  -->  00:01:01,946
This is because the dhcp server is gone.

13

00:01:02,481  -->  00:01:07,150
Now let’s start configuring svi on multi
layer switch.

14

00:01:07,724  -->  00:01:13,295
Later, the communication between vlan will
go through this multi layer switch.

15

00:01:14,149  -->  00:01:21,674
If you remember, I already said that if computer
want to communicate with other computers that

16

00:01:21,674  -->  00:01:27,418
in the different network, the computer will
be need a default gateway.

17

00:01:27,915  -->  00:01:34,418
So in this case, the default gateway will
be the ip address of multi layer switch.

18

00:01:36,000  -->  00:01:41,297
So now we need to configure an ip address
in the multi layer switch.

19

00:01:42,445  -->  00:01:43,357
Let’s start.

20

00:01:43,880  -->  00:01:52,149
Go to CLI, enable, and then go to global configuration
mode.

21

00:01:52,838  -->  00:01:56,611
We will need to configure an ip address for
each vlan.

22

00:01:57,618  -->  00:02:03,685
In the router, we need to create sub interface
to configure ip address for each vlan.

23

00:02:04,157  -->  00:02:13,977
So let’s say fa0/0.10 for vlan 10, fa0/0.20
for vlan 20 and others.

24

00:02:14,933  -->  00:02:20,311
But in the multi layer switch, we don’t
need to create sub interface.

25

00:02:20,719  -->  00:02:24,666
We can configure the ip address in the vlan
interface.

26

00:02:25,559  -->  00:02:27,802
Let’s configure for vlan 1 first.

27

00:02:28,439  -->  00:02:39,873
So interface vlan 1, and then the ip address
is 192.168.1.1 255.255.255.0.

28

00:02:40,919  -->  00:02:45,484
Okay here we have done configuring the ip
address of vlan 1.

29

00:02:46,274  -->  00:02:49,382
Next let’s configure for vlan 10.

30

00:02:49,867  -->  00:03:02,256
So go to interface vlan 10, and then the ip
address is 192.168.10.1 255.255.255.0

31

00:03:03,531  -->  00:03:06,665
Next let’s configure for vlan 20.

32

00:03:07,609  -->  00:03:19,796
The ip address is 192.168.20.1 255.255.255.0,
and last let’s configure for vlan 30,

33

00:03:20,318  -->  00:03:28,483
the ip address is 192.168.30.1 255.255.255.0

34

00:03:30,000  -->  00:03:34,428
Okay now we have done configuring ip address
for all vlan.

35

00:03:35,053  -->  00:03:36,365
Let’s verify it.

36

00:03:36,926  -->  00:03:39,097
Do show ip interface brief.

37

00:03:41,469  -->  00:03:44,699
Okay here we can see a lot of interface.

38

00:03:45,745  -->  00:03:48,564
And the interface vlan is in the buttom.

39

00:03:49,724  -->  00:03:57,392
Okay here we can see the ip address for vlan1,
vlan 10, vlan 20, and vlan 30.

40

00:03:58,285  -->  00:04:06,849
But here we can see that for vlan 1, the status
is administrative down, this is means that

41

00:04:06,849  -->  00:04:10,411
we need to use no shutdown in vlan 1.

42

00:04:11,418  -->  00:04:19,875
And here for vlan 30, the status is down,
this is because we don’t have vlan 30 yet

43

00:04:19,875  -->  00:04:21,480
in this multi layer switch.

44

00:04:21,862  -->  00:04:25,073
Let’s check it, do show vlan brief.

45

00:04:25,825  -->  00:04:29,768
Okay here we can see that we don’t have
vlan 30 yet.

46

00:04:30,635  -->  00:04:38,407
If we see in the topology, actually we don’t
have vlan 30 that attached to multi layer switch.

47

00:04:39,000  -->  00:04:47,311
But because this multilayer switch will become
gateway and in the room 1 we have vlan 30,

48

00:04:47,642  -->  00:04:52,653
so we also need to create vlan 30 in this
multi layer switch.

49

00:04:53,520  -->  00:04:54,962
So let’s create it.

50

00:04:55,625  -->  00:04:59,243
Vlan 30, the name is engineering.

51

00:05:01,105  -->  00:05:08,888
Let’s check the vlan again, okay here we
can see that now we have vlan 30.

52

00:05:09,870  -->  00:05:15,749
Now let’s see the ip address again, do show
ip interface brief.

53

00:05:16,642  -->  00:05:20,288
Okay here we can see that vlan 30 is up.

54

00:05:21,117  -->  00:05:29,158
For vlan 1, this is still administrative down,
remember that if the status is administrative

55

00:05:29,158  -->  00:05:34,824
down like this, this is means we need to no
shutdown the interface.

56

00:05:35,589  -->  00:05:40,068
Let’s go to interface vlan 1, and then no
shutdown.

57

00:05:41,203  -->  00:05:46,234
Let’s check again, do show ip interface
brief.

58

00:05:48,351  -->  00:05:52,510
Okay here we can see that the status is already
up.

59

00:05:54,065  -->  00:06:00,377
Okay for now we have done configuring the
ip address for all vlan in the multi layer switch.

60

00:06:00,981  -->  00:06:07,260
I think enough for this video, in the next
video, we are going to configure the ip address

61

00:06:07,260  -->  00:06:11,302
in all pc and test connection between vlan.

62

00:06:12,156  -->  00:06:16,486
Okay thankyou for watching and see you on
the next video.
