1

00:00:00,461  -->  00:00:04,145
In the previous video, we already learn about
vlan.

2

00:00:04,813  -->  00:00:09,000
Next in this video we are going to learn about
trunk.

3

00:00:09,656  -->  00:00:11,338
So what is trunk?

4

00:00:12,000  -->  00:00:19,234
We will about learn trunk by doing, but before
that, we need to create another topology first.

5

00:00:19,842  -->  00:00:24,970
Here let’s add one more switch, and then
add some pc,

6

00:00:26,306  -->  00:00:29,291
let’s say here we will need 4 pc.

7

00:00:30,000  -->  00:00:36,307
But here I just add 2 new pc, and bring this
2 pc here.

8

00:00:37,297  -->  00:00:48,608
Let’s also change the name of the PC. Here
the last is pc 4, so this is pc 5, pc 6, pc 7,

9

00:00:48,608  -->  00:00:50,714
and this is pc 8.

10

00:00:51,943  -->  00:00:58,026
Okay now here we will configure this new switch
exactly same with the old switch.

11

00:00:59,648  -->  00:01:08,144
So here we will configure pc 5 and pc 6 to vlan
10, and pc 7 and pc 8 to vlan 20.

12

00:01:08,979  -->  00:01:15,471
Before configure the vlan, let’s change
the name of the switch first, this is switch 1

13

00:01:15,471  -->  00:01:17,501
and this is switch 2.

14

00:01:18,323  -->  00:01:21,485
Now let’s configure the vlan in switch 2.

15

00:01:22,273  -->  00:01:31,455
Here we can see fa0/1 and fa0/2, so this two
interface will be in the vlan 10.

16

00:01:31,777  -->  00:01:41,214
And here we have fa0/3 and fa0/4, this two
interface will be in the vlan 20.

17

00:01:42,275  -->  00:01:43,678
Okay let’s start.

18

00:01:44,465  -->  00:01:50,185
Enable, configure terminal, and then create
the vlan.

19

00:01:51,103  -->  00:01:57,479
Vlan 10, the name is accounting, next let’s
create for vlan 20.

20

00:01:58,064  -->  00:02:01,960
Vlan 20, and then the name is marketing.

21

00:02:03,000  -->  00:02:06,600
Let’s see the vlan, show vlan brief.

22

00:02:08,281  -->  00:02:12,787
Okay here we can see that we have vlan 10
and vlan 20,

23

00:02:13,240  -->  00:02:16,905
but all of interface is still in vlan 1.

24

00:02:17,752  -->  00:02:25,473
Next, let’s assign interface fa0/1 and fa0/2
to vlan 10.

25

00:02:27,000  -->  00:02:36,632
Interface range fa0/1-2 . In the previous
video, I show you how to assign interface

26

00:02:36,632  -->  00:02:38,636
to vlan one by one.

27

00:02:39,185  -->  00:02:49,883
So we go to interface fa0/1, assign the interface
to vlan 10, then go to interface fa0/2 and

28

00:02:49,883  -->  00:02:53,026
assign the interface again to vlan 10.

29

00:02:53,742  -->  00:02:59,822
But now, here I show you how to assign multiple
interface to a vlan at once,

30

00:02:59,822  -->  00:03:03,000
here we can use range.

31

00:03:03,613  -->  00:03:11,557
So interface range fa0/1-2, then switchport
mode access,

32

00:03:13,191  -->  00:03:16,730
and finally switchport access vlan 10.

33

00:03:17,720  -->  00:03:25,552
This is means that we assign interface fa0/1
and fa0/2 to vlan 10.

34

00:03:25,719  -->  00:03:27,207
Now let’s verify it.

35

00:03:27,577  -->  00:03:36,452
Here we can see that now
interface fa0/1 and fa0/2 is already in the vlan 10.

36

00:03:37,485  -->  00:03:41,513
Next let’s assign the interface for vlan
20.

37

00:03:42,181  -->  00:03:53,655
Interface range fa0/3-4, switchport mode access,
and then switchport access vlan 20.

38

00:03:54,239  -->  00:03:55,559
Let’s verify it.

39

00:03:57,992  -->  00:04:07,408
Okay here we can see that interface fa0/3
and fa0/4 is already in the vlan 20.

40

00:04:08,649  -->  00:04:15,620
Next let’s configure the ip address of all
pc. In this case, we will configure the ip

41

00:04:15,620  -->  00:04:18,687
address of all vlan with same block subnet.

42

00:04:19,355  -->  00:04:25,780
But always remember that in the production,
each vlan must be use different block subnet.

43

00:04:26,591  -->  00:04:30,739
Here I use same block subnet for all vlan
just for learning.

44

00:04:31,896  -->  00:04:37,931
Okay here pc 5 the ip address is 192.168.1.5,

45

00:04:38,909  -->  00:04:54,724
pc 6 the ip address is 192.168.1.6, pc 7 the ip address
is 192.168.1.7 and last pc 8 the ip address

46

00:04:54,724  -->  00:04:58,371
is 192.168.1.8.

47

00:04:59,659  -->  00:05:01,491
Okay now we have done.

48

00:05:01,932  -->  00:05:06,136
For the testing, let’s send packet between
pc in the same vlan.

49

00:05:08,271  -->  00:05:09,666
Okay here success.

50

00:05:10,024  -->  00:05:12,898
So between pc in the vlan 10 is ok.

51

00:05:13,363  -->  00:05:16,185
Next let’s test for vlan 20.

52

00:05:16,877  -->  00:05:19,046
Okay here also success.

53

00:05:20,048  -->  00:05:26,173
Okay I think enough for this video, in the
next video, we are going to learn about trunk.

54

00:05:26,531  -->  00:05:29,900
Thankyou for watching and see you on the next
video.
