1

00:00:00,447  -->  00:00:06,468
In this section, we are going to learn about
access list, what is access list?

2

00:00:06,940  -->  00:00:12,895
Access list is a policy to accept or block
any packet in the network.

3

00:00:13,671  -->  00:00:17,688
We are going to learn about access list with
an example case.

4

00:00:18,464  -->  00:00:20,750
Let’s create the topology first.

5

00:00:21,439  -->  00:00:31,135
Let’s import 2 router, change the name,
this is router 1 and this is router 2.

6

00:00:32,000  -->  00:00:42,171
And then let’s also import switch, let’s
change the name, this is switch 1

7

00:00:44,000  -->  00:00:46,000
and this is switch 2.

8

00:00:47,695  -->  00:00:56,075
Connecting router 1 to switch 1, router 2 to
switch 2, and router 1 to router 2.

9

00:00:57,003  -->  00:01:06,953
Now let’s also import some pc, let’s say
here we need 6 pc, this will be separated to 3 vlans.

10

00:01:07,331  -->  00:01:10,108
And let’s also import 3 server.

11

00:01:10,855  -->  00:01:21,068
Let’s connecting switch 1 to all pc, and
then connecting switch 2 to all server.

12

00:01:23,892  -->  00:01:46,421
Here we will create 3 vlan for pc. This is
vlan 10, this is vlan 20, and this is vlan 30.

13

00:01:47,239  -->  00:01:50,576
For the server, we will don’t configure
a vlan.

14

00:01:54,000  -->  00:02:07,549
For the ip addressing, vlan 10 will use 192.168.10.0/24,
vlan 20 will use 192.168.20.0/24,

15

00:02:07,932  -->  00:02:13,263
and vlan 30 will use 192.168.30.0/24.

16

00:02:14,996  -->  00:02:21,198
For the server, let’s say we will use 192.168.1.0/24.

17

00:02:22,758  -->  00:02:29,316
For the interface between routers, here will
be 10.10.10.1/30,

18

00:02:32,093  -->  00:02:37,210
and in the router 2 will be 10.10.10.2/30.

19

00:02:38,091  -->  00:02:42,824
So this is topology that we are going to use
to learn about access list.

20

00:02:43,619  -->  00:02:51,216
This is a task for you, try to configure this
topology, the goal is all pc will able to

21

00:02:51,216  -->  00:02:53,161
communicate with servers.

22

00:02:53,860  -->  00:02:59,752
I will show you the solution in the next video,
but before you watch the solution,

23

00:02:59,887  -->  00:03:02,176
make sure that you try it first.

24

00:03:03,162  -->  00:03:06,000
Okay I think enough for this video.

25

00:03:06,239  -->  00:03:09,519
Thankyou for watching and see you on the next video.
