In the previous video, we already configure static routing in two router. 2
Next in this video, we are going to add 1 more router. 3
Let’s just start, import new router, and also import 1 new pc. 4
Connect the pc to the router, 5
and we also need to connecting router 2 with new router, 6
but let’s change the router name first, let’s say this is router 3. 7
The problem is, this router is only have 2 interface. Let’s check it, 8
do show ip interface brief, here we can see that we only have fa0/0 and fa0/1. 9
So we can not connecting router 2 to router 3. 10
Let’s try it. Here we get an error the cable cannot be connected to that port. 11
So we need to add additional interface in router 2. 12
But before that, let’s save the configuration first. 13
Then go to physical, 14
let’s shutdown the router. 15
Now let’s add new interface, we will use NM-1FE-TX, okay let’s turn on the router again. 16
Let’s try to connecting router 2 to router 3 again, 17
okay here we can see that we can connecting router 2 to router 3, the interface is fa1/0. 18
Next for ip addressing, in the router 2, 19
the ip address will be 10.20.20.1/24, router 3 will be 10.20.20.2/24. 20
And then router 3 that connected to pc 3, the ip address will be 21
192.168.3.1/24, and in the pc, the ip address will be 192.168.3.10/24. 22
Okay now let’s start the configuration, let’s start from router 2. Enable, configure terminal, 23
interface fa1/0, no shutdown, and the ip address is 10.20.20.1 255.255.255.0. 24
Okay we have done in router 2, next let’s configure router 3. 25
No, enable, configure terminal, interface fa0/1, 26
no shutdown, the ip address is 10.20.20.2 so here 10.20.20.2 255.255.255.0. 27
Next let’s configure fa0/0, the ip address is 192.168.3.1 255.255.255.0. 28
Here we can see that the light is red, so we need to no shutdown. Let’s check it first, 29
do show ip interface brief, okay here I do a mistake. 30
Let’s configure the ip address of fa0/1 again, ip address 10.20.20.2 255.255.255.0, 31
and then go to int fa0/0, no shutdown, here we can see that now the light is green. 32
And then the ip address is 192.168.3.1 255.255.255.0. 33
Okay now we have done in router 3. Last, let’s configure the ip address of pc 3. 34
Desktop, ip configuration, the ip address is 192.168.3.10, the gateway is 192.168.3.1. 35
Okay now we have done, configuring an ip address in all router and pc. 36
Now let’s analyze the routing. 37
In the previous video, we already add static routing in router 1, let’s write it, 38
S this is means static, the destination is 192.168.2.0/24 and the next hop is 10.10.10.2. 39
In the router 2, we also already add static routing, let’s write it, 40
the destination is 192.168.1.0/24 and the next hop is 10.10.10.1. 41
Last for router 3, we don’t configure static routing yet, 42
so router 3 should have only 2 network in the routing table, 43
which is 10.20.20.0/24 and 192.168.3.0/24, because this two network is connected to router 3. 44
Let’s write it. 10.20.20.0/24 is in fa0/1, and 192.168.3.0/24 is in fa0/0. 45
Oh ya one more thing, in router 2 must be have new entry in the routing table, 46
which is 10.20.20.0/24, because this is connected to router2, and this network is connected to fa1/0. 47
Okay I think enough for this video, in the next video, we are going to configure static routing 48
so pc 3 can communicate with pc 1 and pc 2. 49
Thankyou for watching and see you on the next video.
