Ada tiga (3) elemen dasar konfigurasi OSPF:

• Enable OSPF instance
• OSPF area configuration
• OSPF network configuration

Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.

R1

vtysh
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.10.1.0/30 area 0.0.0.0
  network 10.10.1.4/30 area 0.0.0.0
  end

R2

vtysh
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.10.1.4/30 area 0.0.0.0
  network 10.10.1.8/30 area 0.0.0.0
  network 172.16.0.0/16 area 0.0.0.0
  end

R3

vtysh
configure terminal
  !
  ! area 0 = backbone
  router ospf
  network 10.10.1.0/30 area 0.0.0.0
  network 10.10.1.8/30 area 0.0.0.0
  network 192.168.1.0/24 area 0.0.0.0
  end
