Ada tiga (3) elemen dasar konfigurasi OSPF:

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

instance name=default sudah ada, tidak perlu di tambahkan, tapi kalau perlu menambahkan caranya adalah sebagai berikut

R1: 

enable
configure terminal
  router ospf default
  end

R2: 

enable
configure terminal
  router ospf default
  end

R3: 

enable
configure terminal
  router ospf default
  end

Cek 

/routing ospf instance print 

Flags: X - disabled 
 0   name="default" router-id=0.0.0.0 distribute-default=never 
     redistribute-connected=as-type-1 redistribute-static=as-type-1 
     redistribute-rip=no redistribute-bgp=no redistribute-other-ospf=no 
     metric-default=1 metric-connected=20 metric-static=20 metric-rip=20 
     metric-bgp=auto metric-other-ospf=auto in-filter=ospf-in 
out-filter=ospf-out


Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.

R1 

enable
configure terminal
  !
  ! area 0 = backbone
  network 10.10.1.0 0.0.0.3 area 0
  network 10.10.1.4 0.0.0.3 area 0
  end

R2 

enable
configure terminal
  !
  ! area 0 = backbone
  network 10.10.1.4 0.0.0.3 area 0
  network 10.10.1.8 0.0.0.3 area 0
  network 172.16.0.0 0.0.255.255 area 0
  end

R3 

enable
configure terminal
  !
  ! area 0 = backbone
  network 10.10.1.0 0.0.0.3 area 0
  network 10.10.1.8 0.0.0.3 area 0
  network 192.168.1.0 0.0.0.255 area 0
  end

Verify

Cek di R1, R2, R3 

/routing ospf interface print
/routing ospf neighbor print
/ip route print

Lakukan yang sama untuk R2, R3
