Konfigurations eksemplet for OSPF konfigureres på dette setup. Det kører allerede RIP og vi skal nu tilføje OSPF og når OSPF har konvergeret erstatter vi RIP med OSPF i route tabellen

Konfigurations rækkefælgen bliver:

  1. Konfigurer OSPF
  2. Verificer OSPF
  3. Fjern RIP.

Konfiguration af OSPF

Her konfigureres OSPF[1] så forbindelserne imellem routerne tilhører Area 0 og Lo interfaces tilhører et Area med samme nummer som P-Routeren(P1 = Area 1)
Route Preference konfigureres til at være højere end RIP, så vi ikke mister routing imens OSPF konvergerer.

Deaktiver RIP

Først ændrer vi Global route Preference til default og så fjerner vi RIP.

Her kan vi se at alle netværk er lært via både RIP og OSPF. RIP Routen er den aktive(*).
