In the previous video, we already learn about the differences between static routing and 2
dynamic routing. 3
We know that if we use dynamic routing, each router will advertise their connected network, 4
so here router 1 will advertise 10.10.10.0/24 and 192.168.1.0/24. 5
Router 2 will advertise 10.10.10.0/24 and 192.168.2.0/24. 6
Okay, next for dynamic routing, we have some protocol that we can use. 7
The first protocol is RIP. 8
But this protocol is not used anymore 9
And then we can use EIGRP, this is cisco proprietary, so we only can use this protocol in cisco 10
devices. 11
If we use other vendor, we can not use EIGRP. 12
Next, we have OSPF, this is open protocol. 13
So we can use this protocol on any vendor. 14
Next we have BGP. 15
This is also open protocol. 16
But the usage is different with eigrp and ospf. 17
We will talk more about bgp later in the next video. 18
In this video, we will learn about EIGRP first. 19
Let’s just start, open router 1, enable, configure terminal, to configure eigrp, 20
the command is router eigrp and then question mark, here we need to define an autonomous 21
system number. 22
What is autonomous system number? 23
We will learn about this later when we learn about bgp. 24
For now let’s just choose random number between 1 and 65535. 25
Let’s say here I use 10. 26
One thing that you need to remember is, in eigrp, all router must use same autonomous 27
system number, so here if we use 10 in router 1, later in router 2 also must use 10. 28
Next, let’s advertise the connected network, here in router 1, the connected network is 29
10.10.10.0/24 and 192.168.1.0/24. 30
So we need to advertise this two network. 31
The command is network and then the network, let’s advertise 10.10.10.0 first. 32
Next let’s advertise 192.168.1.0. 33
Okay now we have done on router 1. 34
Next let’s configure on router 2. 35
Enable, configure terminal, router eigrp 10, remember that we must use the same autonomous 36
system number on all router. 37
Next, let’s advertise the connected network, here router 2 also have 2 connected network, 38
which is 10.10.10.0/24 and 192.168.2.0/24. 39
Let’s advertise it. 40
Network 10.10.10.0 and then network 192.168.2.0 41
Here we can see a message neighbor 10.10.10.1 is up, this is means that the eigrp is up. 42
To verify it, we can use command do show ip eigrp neighbor. 43
Here we can see that we have a neighbor 10.10.10.1 which Is the ip address of router 1, 44
Let’s check the routing table, do show ip route, here we can see that we have 2 connected route, 45
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
This route is added automatically by eigrp. 47
Here we can see that the destination is the network of pc 1, and the next hop is router 1. 48
The label is D. D is means eigrp. 49
Now let’s check on router 1, do show ip route, here we can see that router 1 also have route 50
to pc 2, and this is also added automatically. 51
Now pc 1 should be able to communicate with pc 2, let’s try it, ping 192.168.2.2, 52
Okay here we can see that the ping is success. 53
I think enough for this video, in the next video, we are going to add 1 more router to 54
our topology. 55
Thank you for watching and see you on the next video.
