00:00:00,610  -->  00:00:05,404
In the previous video, we have done configuring inter vlan routing.

2

00:00:05,904  -->  00:00:10,028
And now all vlan can communicate each others.

3

00:00:10,664  -->  00:00:17,419
But for now we need to configure the ip
address of all pc one by one manually.

4

00:00:18,597  -->  00:00:23,297
In this video we are going
to learn about dhcp server.

5

00:00:23,824  -->  00:00:31,750
If we configure a dhcp server, we don’t need to
configure the ip address of pc manually anymore.

6

00:00:32,478  -->  00:00:38,830
Okay let’s just start, we will
configure dhcp server in the router.

7

00:00:39,840  -->  00:00:43,840
Enable, and then go to global configuration mode.

8

00:00:44,560  -->  00:00:53,753
To configure dhcp server, the command is ip dhcp
pool and then the name of the pool.

9

00:00:54,159  -->  00:01:02,092
We can use anything for the pool name. But usually we
will use the vlan number or the vlan name

10

00:01:02,092  -->  00:01:08,537
for the pool name, for example
we can use vlan 10 or accounting.

11

00:01:09,104  -->  00:01:17,164
But actually we can use anything for the pool
name. For now, let’s say I will use vlan10.

12

00:01:18,649  -->  00:01:26,563
Next we need to define a network,
because this pool is for vlan 10,

13

00:01:27,451  -->  00:01:37,592
so the network is 192.168.10.0 and
the subnetmask is 255.255.255.0.

14

00:01:38,423  -->  00:01:41,760
Next we will need to configure default-router,

15

00:01:42,560  -->  00:01:50,190
the default router will become the gateway for
the pc in the vlan 10. So here default-router

16

00:01:50,411  -->  00:02:00,365
and then the gateway for vlan 10, which is the
ip address of router it self, so 192.168.10.1.

17

00:02:01,317  -->  00:02:10,678
Next we also can configure dns. So dns-server and
the the dns server, usually we will use google

18

00:02:10,678  -->  00:02:21,109
dns server, which is 8.8.8.8. Okay now we have
done configuring the dhcp server for vlan 10.

19

00:02:21,717  -->  00:02:28,030
To test it, we can configure the
dhcp client in all of pc vlan 10.

20

00:02:29,184  -->  00:02:39,671
Let’s start from room 1. Here we can choose dhcp,
and here we can see that dhcp request successful.

21

00:02:40,304  -->  00:02:46,018
Here we can see that the
ip address is 192.168.10.2,

22

00:02:46,491  -->  00:02:52,791
this ip address is automatically
assigned to the pc by dhcp server.

23

00:02:53,918  -->  00:02:57,497
Let’s configure dhcp client in the other pc.

24

00:03:01,838  -->  00:03:11,152
Here we can see that this is also success.
Next this is also vlan 10, here also success,

25

00:03:11,636  -->  00:03:22,764
Next let’s try here. This is also
success, the ip address is 192.168.10.5.

26

00:03:23,624  -->  00:03:32,577
Last, let’s configure for vlan 10 in room 3,
okay here success, the ip address is 10.6,

27

00:03:33,331  -->  00:03:39,804
and last here this is also
success. The ip address is 10.7.

28

00:03:40,451  -->  00:03:45,840
Okay so now the dhcp server
configuration for vlan 10 is done.

29

00:03:46,345  -->  00:03:58,310
Next let’s configure dhcp server for vlan 1.
Ip dhcp pool vlan1, the network is 192.168.1.0

30

00:03:58,612  -->  00:04:08,683
and the subnetmask is 255.255.255.0. The default
router is the ip address of router for vlan 1,

31

00:04:09,065  -->  00:04:17,750
which is 192.168.1.1. and
the dns server is 8.8.8.8.

32

00:04:18,000  -->  00:04:32,325
Next for vlan 20. Ip dhcp pool vlan 20.
The network is 192.168.20.0 255.255.255.0,

33

00:04:32,720  -->  00:04:41,057
default router 192.168.20.1,
and then dns-server 8.8.8.8.

34

00:04:41,412  -->  00:04:56,638
Last for vlan 30, ip dhcp pool vlan 30.
Network 192.168.30.0 255.255.255.0

35

00:04:57,464  -->  00:05:06,457
default router 192.168.30.1,
and dns-server 8.8.8.8

36

00:05:07,370  -->  00:05:12,377
Okay now we have done configuring
dhcp server for all vlan.

37

00:05:12,997  -->  00:05:17,006
Now let’s configure dhcp client on all pc.

38

00:05:18,665  -->  00:05:24,000
I will speed up the video until the
configuration off all pc is done.

39

00:05:28,717  -->  00:05:35,219
Okay so now all pc can get an ip address
automatically from dhcp server.

40

00:05:35,801  -->  00:05:40,392
I think enough for this video and see you on the next video!
