Konfigurasi IP Address di PC silahkan di browsing di tempat lain. Sampai disini kita anggap semua PC sudah ter-konfigurasi IP Address. Selanjutnya kita akan melakukan Konfigurasi Routing OSPF.

Lihat hasil konfigurasi, apakah pada table route sudah terdapat routing ospf?
RT1#sh ip route
Codes: L - local, C - connected, S - static, 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

Oke, Sampai disini kita bisa lihat bahwa routing OSPF sudah masuk didalam table route yaitu dengan kode O (OSPF). Selanjutnya kita juga bisa melakukan tes koneksi dari dengan menggunakan perintah PING dan perintah TRACERT untuk melihat jalur yang dilewati. Sebagai contoh kita akan melakukan perintah ping dari PC1 ke tujuan PC3, lihat dibawah hasilnya.
Perintah PING
PC>ping 192.168.3.2
Pinging 192.168.3.2 with 32 bytes of data:
