    ip address 10.0.1.1/30
    no shutdown
    exit
  interface eth2
    ip address 10.1.1.1/30

Setup OSPF

R1:

enable
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.0.1.0 0.0.0.255 area 0.0.0.0
  network 10.1.1.0 0.0.0.3 area 0.0.0.1
  end

R2:

enable
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.0.1.0 0.0.0.255 area 0.0.0.0
  network 10.1.2.0 0.0.0.3 area 0.0.0.2
  end

R3 configuration:

enable

  ! network 192.168.1.0 0.0.0.255 area 0.0.0.1
  end

R4 configuration:

enable
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.1.2.0 0.0.0.3 area 0.0.0.2
  ! network 192.168.2.0 0.0.0.255 area 0.0.0.2
  end

Cek route

Cek R1, R2, R3, R4:

show ip ospf neighbor
show ip ospf database 
show ip route

Redistribute Connected

R3:

enable
configure terminal
router ospf 3
  redistribute connected
  end

R4:

enable
configure terminal
router ospf 4
  redistribute connected
  end

Cek

show ip ospf neighbor
