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

enable
configure terminal
  !
  ! area 0 = backbone
  router ospf 1
  network 10.10.1.0 0.0.0.3 area 0.0.0.0
  network 10.10.1.4 0.0.0.3 area 0.0.0.0
  ipv6 router ospf 1
    router-id 10.10.1.1 area 0.0.0.0
  end


R2

enable
configure terminal
  !
  ! area 0 = backbone
  router ospf 2
  network 10.10.1.4 0.0.0.3 area 0.0.0.0
  network 10.10.1.8 0.0.0.3 area 0.0.0.0
  network 172.16.0.0 0.0.255.255 area 0.0.0.0
  ipv6 router ospf 2
    router-id 10.10.1.5 area 0.0.0.0
  end

R3

enable
configure terminal
  !
  ! area 0 = backbone
  router ospf 3
  network 10.10.1.0 0.0.0.3 area 0.0.0.0
  network 10.10.1.8 0.0.0.3 area 0.0.0.0
  network 192.168.1.0 0.0.0.255 area 0.0.0.0
  ipv6 router ospf 3
    router-id 10.10.1.2 area 0.0.0.0
  end
