==Topologi==

R1
 e1 -- R3: e1
 e2 -- R2: e1
 e3 -- NAT: Internet

R2
 e1 -- R1: e2
 e2 -- R3: e2
 e3 -- LAN 172.16.1.1

R3
 e1 -- R1: e1

==Konfigurasi==

Router1:

 vtysh
 configure terminal
   interface eth1
     ip address 10.10.1.1/30
     ip ospf message-digest-key 1 md5 $AP7i1
     no shutdown
     exit
   interface eth2
     ip address 10.10.1.5/30
     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

Router2:

 vtysh
 configure terminal
   interface eth1
     ip address 10.10.1.6/30
     ip ospf message-digest-key 1 md5 $AP7i1
     no shutdown
     exit
   interface eth2
     ip address 10.10.1.9/30
     ip ospf message-digest-key 1 md5 $AP7i1
     no shutdown
     exit
   interface eth3
     ip address 172.16.1.1/16
     no shutdown
     end

Router3:

 vtysh
 configure terminal
   interface eth1
     ip address 10.10.1.2/30
     ip ospf message-digest-key 1 md5 $AP7i1
     no shutdown
     exit
   interface eth2
     ip address 10.10.1.10/30
     ip ospf message-digest-key 1 md5 $AP7i1
     no shutdown
     exit
   interface eth3
     ip address 192.168.1.1/24
     no shutdown
     end

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

 vtysh
 configure terminal
   !
   ! area 0 = backbone
   router ospf
   network 10.10.1.0/30 area 0.0.0.0
   network 10.10.1.4/30 area 0.0.0.0
   area 0.0.0.0 authentication message-digest
   end

R2

 vtysh
 configure terminal
   !
   ! area 0 = backbone
   router ospf
   network 10.10.1.4/30 area 0.0.0.0
   network 10.10.1.8/30 area 0.0.0.0
   network 172.16.0.0/16 area 0.0.0.0
   area 0.0.0.0 authentication message-digest
   end

R3

 vtysh
 configure terminal
   !
   ! area 0 = backbone
   router ospf
   network 10.10.1.0/30 area 0.0.0.0
   network 10.10.1.8/30 area 0.0.0.0
   network 192.168.1.0/24 area 0.0.0.0
   area 0.0.0.0 authentication message-digest
   end

==Verify==

Cek di R1, R2, R3

 show ip ospf neighbor
 show ip ospf database 
 show ip route
