Konfigurasi OSPF Routing - Cisco Packet Tracer


Assalamu'alaikum wr.wb

Kali ini kita akan belajar bagaimana cara mengkonfigurasi OSPF Routing pada Cisco Packet Tracer. OSPF atau Open Shortest Path First merupakan salah satu protocol routing Link State yang bersifat open, sehingga hampir semua router mendukung routing Protocol ini. OSPF membagi router-router kedalam beberapa area. Dalam sebuah routing OSPF harus terdapat Area 0 atau area backbone dimana semua area harus terhubung langsung dengan area 0 tersebut. untuk lebih jelasnya kalian dapat membaca artikel Static Routing dan Dynamic Routing untuk penjelasan yang lebih detail.
Baiklah langsung saja berikut adalah langkah-langkah untuk mengkonfigurasi OSPF Routing pada Cisco Packet Tracer :


Topology




Setting IP Router dan Client

Client

1. Klik icon PC atau Laptop lalu pilih tab Desktop


2. Pilih menu IP Configuration


3. Lakukan langkah 1 dan 2 pada semua PC dengan IP sesuai dengan topology



Konfigurasi Routing OSPF

Router0

Router(config)#router ospf 10
Router(config-router)#net 10.10.10.0 ?
A.B.C.D OSPF wild card bits
Router(config-router)#net 10.10.10.0 0.0.0.3 area 0
Router(config-router)#net 40.40.40.0 0.0.0.3 area 0
Router(config-router)#net 11.11.11.0 0.0.0.3 area 1

NB : Masukkan semua network yang terhubung langsung ke router, untuk wildcard mask diisi dengan subnet mask yang setiap oktetnya dikurangi dengan 255 dan apabila hasilnya negative ubah jadi positif


Router1

Router(config)#router ospf 10
Router(config-router)#net 10.10.10.0 0.0.0.3 area 0
Router(config-router)#net 20.20.20.0 0.0.0.3 area 0
Router(config-router)#net 22.22.22.0 0.0.0.3 area 2

Router2

Router(config)#router ospf 10
Router(config-router)#net 20.20.20.0 0.0.0.3 area 0
Router(config-router)#net 30.30.30.0 0.0.0.3 area 0
Router(config-router)#net 33.33.33.0 0.0.0.3 area 3

Router3

Router(config)#router ospf 10
Router(config-router)#net 30.30.30.0 0.0.0.3 area 0
Router(config-router)#net 40.40.40.0 0.0.0.3 area 0
Router(config-router)#net 44.44.44.0 0.0.0.3 area 4

Router4

Router(config)#router ospf 10
Router(config-router)#net 11.11.11.0 0.0.0.3 area 1
Router(config-router)#net 192.168.1.0 0.0.0.255 area 1

Router5

Router(config)#router ospf 10
Router(config-router)#net 22.22.22.0 0.0.0.3 area 2
Router(config-router)#net 192.168.2.0 0.0.0.255 area 2

Router6

Router(config)#router ospf 10
Router(config-router)#net 33.33.33.0 0.0.0.3 area 3
Router(config-router)#net 192.168.3.0 0.0.0.255 area 3

Router7

Router(config)#router ospf 10
Router(config-router)#net 44.44.44.0 0.0.0.3 area 4
Router(config-router)#net 192.168.4.0 0.0.0.255 area 4


Cek apakah Routing OSPF sudah masuk ke tabel routing

Router0

Router(config-router)#do sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route

Gateway of last resort is not set

40.0.0.0/30 is subnetted, 1 subnets

44.0.0.0/30 is subnetted, 1 subnets
O IA 44.44.44.0 [110/65] via 40.40.40.1, 00:03:00, FastEthernet0/1
O 192.168.1.0/24 [110/65] via 11.11.11.2, 00:02:22, Serial0/0/0
O IA 192.168.2.0/24 [110/66] via 10.10.10.2, 00:01:49, FastEthernet0/0

O IA 192.168.4.0/24 [110/66] via 40.40.40.1, 00:00:51, FastEthernet0/1

Lakukan pengecekan pada semua router


Pengujian

Lakukan test ping antar router dan juga client

Router 0 > Router6 dan Router7

Router#ping 33.33.33.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 33.33.33.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/4/11 ms

Router#ping 44.44.44.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 44.44.44.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/5 ms

Client Router7 > Client Router5

1. Klik pada ikon PC, setelah itu pilih tab desktop




2. Klik pada menu Command Prompt lalu PING IP Client Router5


Apabila semua Router dan Client telah terhubung, maka OSPF telah berjalan dengan baik

Sekian yang dapat saya sampaikan, kurang lebihnya mohon maaf. Apabila ada yang masih belum paham dapat bertanya di kolom komentar. Semoga artikel kali ini bermanfaat. Terimakasih
