In this video, we are going to add some more router to our topology. 2
Let’s add 3 more router, so we will have 5 router in the topology. Let’s just start. 3
We will use 2691 series. 4
We can add some router at once by using shift, so here shift and then drag and drop the router. 5
Here we can type how many router that we want to import. Let’s import 3 router here. 6
Here we can see that we import 3 router at once. this is router 1, router 2, router 3, router 4, 7
and this is router5. 8
Let’s connecting router 3 to the switch, router 4 to the switch and router 5 to the switch. 9
Next let’s configure the ip address for router 3 4 and 5. And we also need to configure ssh 10
so we can remote the router from ubuntu server. 11
Let’s just start, start the router, 12
Here router 3, the ip address will be 10.10.10.3/24, router4 will be 10.10.10.4/24, 13
and router5 will be 10.10.10.5/24. 14
Let’s configure on router 3 first, configure terminal, the interface is fa0/0, 15
so here interface fa0/0, no shutdown, and the ip address is 10.10.10.3 255.255.255.0 16
Let’s ping to router 1, ping 10.10.10.1, 17
okay this is success, ping to ubuntu server do ping 10.10.10.254. okay this is also success. 18
Next let’s configure ssh. Configure domain name first, ip domain-name mydomain.local, 19
Next, let’s create the key, crypto key generate rsa, the modulus is 1024. 20
Next let’s create username and password, username cisco privilege 15 secret cisco. 21
Last let’s configure the vty, line vty 0 15, login local. 22
Okay we have done configuring ssh on router 3. 23
Let’s try to remote the router3 from ubuntu server. 24
Here let’s exit first. Now we are in the mac os, let’s remote to ubuntu server, 25
ssh ubuntu and then the ip address of ubuntu server, which is 192.168.56.2. 26
Okay we are success remote the ubuntu server, next, let’s try to ping to router 3. 27
Ping 10.10.10.3, okay this is success, now let’s try to remote router 3, ssh cisco@10.10.10.3 28
Okay we are success remote router 3 from ubuntu server. 29
Last, don’t forget to save the cisco configuration. 30
So when we close the gns3, the cisco configuration will not gone, do write. 31
Okay I think enough for this video, 32
for router 4 and router 5 you can configure the ip address and ssh by your self. 33
Thank you for watching and see you on the next video.
