Setup IP address

R1: 

vtysh
configure terminal
  interface eth1
    ip address 10.0.1.1/30
    ip ospf message-digest-key 1 md5 $AP7i1
    no shutdown
    exit
  interface eth2
    ip address 10.1.1.1/30
    ip ospf message-digest-key 1 md5 $AP7i1
    no shutdown
    exit
 end

R2: 

vtysh
configure terminal
  interface eth1
    ip address 10.0.1.2/30
    ip ospf message-digest-key 1 md5 $AP7i1
    no shutdown
    exit
  interface eth2
    ip address 10.1.2.1/30
    ip ospf message-digest-key 1 md5 $AP7i1
    no shutdown
    exit
  !
  ! NAT GNS3 gw 192.168.122.1
  interface eth3
    ip address 192.168.122.100/24
    ip address 192.168.122.101/24
    ip address 192.168.122.102/24
    no shutdown
    ip route 0.0.0.0/0 192.168.122.1
  end

R3: 

vtysh
configure terminal
  interface eth1
    ip address 10.1.1.2/30
    ip ospf message-digest-key 1 md5 $AP7i1
    no shutdown
    exit
  interface eth2
    ip address 192.168.1.1/24
    no shutdown
    exit
  end

R4: 

vtysh
configure terminal
  interface eth1
    ip address 10.1.2.2/30
    ip ospf message-digest-key 1 md5 $AP7i1
    no shutdown
    exit
  interface eth2
    ip address 192.168.2.1/24
    no shutdown
    exit
  end

Setup OSPF

R1: 

vtysh
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.0.1.0/30 area 0.0.0.0
  network 10.1.1.0/30 area 0.0.0.1
  area 0.0.0.0 authentication message-digest
  area 0.0.0.1 authentication message-digest
  end

R2: 

vtysh
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.0.1.0/30 area 0.0.0.0
  network 10.1.2.0/30 area 0.0.0.2
  area 0.0.0.0 authentication message-digest
  area 0.0.0.2 authentication message-digest
  end

R3: 

vtysh
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.1.1.0/30 area 0.0.0.1
  network 192.168.1.0/24 area 0.0.0.1
  area 0.0.0.1 authentication message-digest
  end

R4: 

vtysh
configure terminal
  !
  ! area 0.0.0.0 = backbone
  router ospf
  network 10.1.2.0/30 area 0.0.0.2
  network 192.168.2.0/24 area 0.0.0.2
  area 0.0.0.2 authentication message-digest
  end

Cek route

Cek R1, R2, R3, R4: 

show ip ospf neighbor
show ip ospf database 
show ip route

Redistribute Connected

R3: 

configure terminal
router ospf
  redistribute connected
  end

R4: 

configure terminal
router ospf
  redistribute connected
  end


Cek 

show ip ospf neighbor
show ip ospf database 
show ip route
