    no shutdown
    exit

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
  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
  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
  end

Verify

Cek di R1, R2, R3 

show ip ospf neighbor
show ip ospf database 
show ip route
