Apa itu OSPF? monggo main-main kesini :D
Oke, mari kita lanjut ke topologi. Masih sama kok seperti topologi pada RIP sebelumnya, hanya beda di routing nya aja... hehe..
- Configure IP pada R1
- Configure IP pada R2
- Configure IP pada R3
- Configure OSPF pada R1
- Configure OSPF pada R2
- Configure OSPF pada R3
Pada OSPF ini yang kita gunakan bukanlah subnet mask, tetapi wildcard mask...
Apa itu wildcard mask? monggo main kesini .. (efek males ngetik..) :p
- Test ping PC 1
- Test ping PC 2
- Test pign PC 3
Sekarang kita lihat route pada masing-masing router:
R1#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

Ket [110/128], [110/129], [110/65] :
- 110 = Administrative Distance
- 128,129, 65 = Cost
Yap, Selesai sudah...
Kalau ada yang salah mohon dikoreksi...
