1

00:00:00,181  -->  00:00:05,793
In the previous video, we already learn about
the differences between static routing and

2

00:00:05,793  -->  00:00:07,175
dynamic routing.

3

00:00:07,855  -->  00:00:14,472
We know that if we use dynamic routing, each
router will advertise their connected network,

4

00:00:15,251  -->  00:00:25,471
so here router 1 will advertise 10.10.10.0/24
and 192.168.1.0/24.

5

00:00:26,275  -->  00:00:35,149
Router 2 will advertise 10.10.10.0/24 and 192.168.2.0/24.

6

00:00:36,410  -->  00:00:41,532
Okay, next for dynamic routing, we have some
protocol that we can use.

7

00:00:42,151  -->  00:00:44,566
The first protocol is RIP.

8

00:00:45,110  -->  00:00:48,130
But this protocol is not used anymore

9

00:00:49,367  -->  00:00:58,179
And then we can use EIGRP, this is cisco proprietary,
so we only can use this protocol in cisco

10

00:00:58,179  -->  00:00:59,297
devices.

11

00:01:00,000  -->  00:01:04,633
If we use other vendor, we can not use EIGRP.

12

00:01:05,771  -->  00:01:10,527
Next, we have OSPF, this is open protocol.

13

00:01:10,898  -->  00:01:14,263
So we can use this protocol on any vendor.

14

00:01:15,203  -->  00:01:17,490
Next we have BGP.

15

00:01:17,762  -->  00:01:20,273
This is also open protocol.

16

00:01:21,163  -->  00:01:25,380
But the usage is different with eigrp and
ospf.

17

00:01:25,763  -->  00:01:30,120
We will talk more about bgp later in the next
video.

18

00:01:30,825  -->  00:01:34,555
In this video, we will learn about EIGRP first.

19

00:01:35,891  -->  00:01:48,229
Let’s just start, open router 1, enable,
configure terminal, to configure eigrp,

20

00:01:48,229  -->  00:01:55,986
the command is router eigrp and then question
mark, here we need to define an autonomous

21

00:01:55,986  -->  00:01:57,479
system number.

22

00:01:57,986  -->  00:02:00,153
What is autonomous system number?

23

00:02:00,685  -->  00:02:05,337
We will learn about this later when we learn
about bgp.

24

00:02:06,166  -->  00:02:12,563
For now let’s just choose random number
between 1 and 65535.

25

00:02:13,516  -->  00:02:15,568
Let’s say here I use 10.

26

00:02:16,421  -->  00:02:23,591
One thing that you need to remember is, in
eigrp, all router must use same autonomous

27

00:02:23,591  -->  00:02:33,200
system number, so here if we use 10 in router 1,
later in router 2 also must use 10.

28

00:02:34,832  -->  00:02:42,399
Next, let’s advertise the connected network,
here in router 1, the connected network is

29

00:02:42,399  -->  00:02:49,036
10.10.10.0/24 and 192.168.1.0/24.

30

00:02:49,605  -->  00:02:52,425
So we need to advertise this two network.

31

00:02:52,944  -->  00:03:01,333
The command is network and then the network,
let’s advertise 10.10.10.0 first.

32

00:03:02,470  -->  00:03:07,392
Next let’s advertise 192.168.1.0.

33

00:03:12,215  -->  00:03:15,351
Okay now we have done on router 1.

34

00:03:15,920  -->  00:03:18,907
Next let’s configure on router 2.

35

00:03:19,377  -->  00:03:25,759
Enable, configure terminal, router eigrp 10,
remember that we must use the same autonomous

36

00:03:25,759  -->  00:03:28,177
system number on all router.

37

00:03:33,285  -->  00:03:40,029
Next, let’s advertise the connected network,
here router 2 also have 2 connected network,

38

00:03:40,227  -->  00:03:47,426
which is 10.10.10.0/24 and 192.168.2.0/24.

39

00:03:47,884  -->  00:03:49,540
Let’s advertise it.

40

00:03:50,616  -->  00:03:58,542
Network 10.10.10.0 and then network 192.168.2.0

41

00:04:00,000  -->  00:04:09,298
Here we can see a message neighbor 10.10.10.1
is up, this is means that the eigrp is up.

42

00:04:09,879  -->  00:04:16,185
To verify it, we can use command do show ip
eigrp neighbor.

43

00:04:19,809  -->  00:04:27,677
Here we can see that we have a neighbor 10.10.10.1
which Is the ip address of router 1,

44

00:04:28,802  -->  00:04:37,301
Let’s check the routing table, do show ip
route, here we can see that we have 2 connected route,

45

00:04:37,499  -->  00:04:50,683
which is 10.10.10.0/24 and 192.168.2.0/24,
and then here we have d 192.168.1.0/24,

46

00:04:51,425  -->  00:04:55,625
This route is added automatically by eigrp.

47

00:04:56,268  -->  00:05:03,000
Here we can see that the destination is the
network of pc 1, and the next hop is router 1.

48

00:05:04,348  -->  00:05:09,171
The label is D. D is means eigrp.

49

00:05:10,086  -->  00:05:18,949
Now let’s check on router 1, do show ip route,
here we can see that router 1 also have route

50

00:05:18,949  -->  00:05:24,000
to pc 2, and this is also added automatically.

51

00:05:25,525  -->  00:05:36,246
Now pc 1 should be able to communicate with
pc 2, let’s try it, ping 192.168.2.2,

52

00:05:38,855  -->  00:05:42,188
Okay here we can see that the ping is success.

53

00:05:43,004  -->  00:05:48,885
I think enough for this video, in the next
video, we are going to add 1 more router to

54

00:05:48,885  -->  00:05:50,345
our topology.

55

00:05:50,926  -->  00:05:54,418
Thank you for watching and see you on the
next video.
