1. Buatlah topologi seperti diatas
  2. Isikan ip address sesuaimasing router dan PC

Di router 1 :

Router(config)#int gig0/0
Router(config-if)#no sh

Router(config-if)#
%LINK-5-CHANGED: Interface GigabitEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up

Router(config-if)#ip add 10.10.10.1 255.255.255.0
Router(config-if)#int gig0/1
Router(config-if)#no sh

Router(config-if)#
%LINK-5-CHANGED: Interface GigabitEthernet0/1, changed state to up


Router(config-if)#ip ad 11.11.11.1 255.255.255.0
Router(config-if)#no sh
Router(config-if)#ex

Di router 2 :

Router(config)#int gig0/0
Router(config-if)#no sh

Router(config-if)#
%LINK-5-CHANGED: Interface GigabitEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/0, changed state to up

Router(config-if)#ip add 11.11.11.2 255.255.255.0
Router(config-if)#int gi0/1
Router(config-if)#no sh

Router(config-if)#
%LINK-5-CHANGED: Interface GigabitEthernet0/1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface GigabitEthernet0/1, changed state to up

Router(config-if)#ip add 12.12.12.1 255.255.255.0
Router(config-if)#e

 3.Lalu konfigurasi OSPF di kedua router

 Di router 1 :

Router(config)#rouos 100
Router(config-router)#net 10.10.10.0 0.0.0.255 are 0
Router(config-router)#net 11.11.11.0 0.0.0.255 are 0
Router(config-router)#

 Di router 2 :

Router(config)#rouos 100
Router(config-router)#net 11.11.11.0 0.0.0.255 are 0
Router(config-router)#net 12.12.12.0 0.0.0.255 are 0
Router(config-router)#

4. Setelah selsai coba ping antara komputer yang ada di sebelah kiri dan kanan dan jangan lupa mengisi ip yang ad di komputer disini tidak saya jelaskan cara mengisi IP komputer, dan hasilnya maka akan reply
