konfigurasi dinamik OSPF VIRTUAL MULTI AREA

KONFIGURASI ROUTING OSPF VIRTUAL MULTI AREA


Bismillah,assalamualaikum wr wb salam sejahtera untuk anda semua,



Berikut Topologinya

1. Mari kita mulai
  pertama tama kita konfigurasi interface di setiap routernya,

ROUTER 1



Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R1
R1(config)#int f0/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#ex
R1(config)#no sh

ROUTER 2

Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R2
R2(config)#int f0/0
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#sh
R2(config-if)#no sh

R2(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

R2(config-if)#ex
R2(config)#int f1/0
R2(config-if)#ip add 23.23.23.1 255.255.255.255
Bad mask /32 for address 23.23.23.1
R2(config-if)#ip add 23.23.23.1 255.255.255.0
R2(config-if)#no sh


ROUTER 3


Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R3
R3(config)#int f1/0
R3(config-if)#ip add 23.23.23.2 255.255.255.0
R3(config-if)#no sh

R3(config-if)#
%LINK-5-CHANGED: Interface FastEthernet1/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/0, changed state to up

R3(config-if)#ex
R3(config)#int f0/0
R3(config-if)#ip add 24.24.24.1 255.255.255.0
R3(config-if)#no sh

R3(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

R3(config-if)#ex
R3(config)#int f2/0

R3(config-if)#ip add 35.35.35.1 255.255.255.0
R3(config-if)#exit

ROUTER 4


Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R4
R4(config)#int f0/0
R4(config-if)#ip add 24.24.24.2 255.255.255.0
R4(config-if)#no sh

R4(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

R4(config-if)#ex
R4(config)#int f1/0
R4(config-if)#ip add 45.45.45.1 255.255.255.0

R4(config-if)#no sh

ROUTER 5



R5(config)#int f2/0
R5(config-if)#ip add 35.35.35.2 255.255.255.0
R5(config-if)#no sh

R5(config-if)#
%LINK-5-CHANGED: Interface FastEthernet2/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet2/0, changed state to up

R5(config-if)#ex
R5(config)#int f1/0
R5(config-if)#ip add 45.45.45.2 255.255.255.0
R5(config-if)#no sh

R5(config-if)#
%LINK-5-CHANGED: Interface FastEthernet1/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet1/0, changed state to up

R5(config-if)#ex
R5(config)#int f0/0
R5(config-if)#ip add 56.56.56.1 255.255.255.0
R5(config-if)#no sh


ROUTER 6


Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R6
R6(config)#int f0/0
R6(config-if)#ip add 56.56.56.2 255.255.255.0
R6(config-if)#no sh

R6(config-if)#
%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

R6(config-if)#ex
R6(config)#int f1/0
R6(config-if)#ip add 67.67.67.1 255.255.255.0
R6(config-if)#no sh


ROUTER 7.

Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R7
R7(config)#int f1/0
R7(config-if)#ip add 67.67.67.2 255.255.255.0

R7(config-if)#no sh

2.   Kemudian kita melakukan loopback pada setiap router 1 sampai 7 dibawah ini, namun di bedakan ip adress seperti router 1 menjadi (1.1.1.1) dan di router 2 menjadi (2.2.2.2) dan seterusnya.dan di bawah ini contohnya

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config-if)#exit

3.  Setelah kita melakukan loopback,kemudian kita melakukan konfigurasi ospf pada setiap router, yang dimana kita isi networknya dan beri area sesuai networknya berada. saya akan memberikan contohnya seperti di bawah ini!

ROUTER 1

R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#router ospf 10
R1(config-router)#network  12.12.12.0 0.0.0.255 area 1
R1(config-router)#network  1.1.1.1 0.0.0.0 area 1

R1(config-router)#



ROUTER 2



R2(config)#router ospf 10
R2(config-router)#net 12.12.12.0 0.0.0.255 area 1
R2(config-router)#net 23.23.23.0 0.0.0.255 area 0
R2(config-router)#net 3.3.3.3 0.0.0.0 area 0
R2(config-router)#ex

ROUTER 3

R3(config)#router ospf 10
R3(config-router)#net 23.23.23.0 0.0.0.255 area 0
R3(config-router)#net 24.24.24.0 0.0.0.255 area 0
R3(config-router)#net 35.35.35.0 0.0.0.255 area 0
R3(config-router)#net 4.4.4.4 0.0.0.0 area 0
R3(config-router)#ex

 ROUTER 4

R4(config)#router ospf 10
R4(config-router)#net 24.24.24.0 0.0.0.255 area 1
R4(config-router)#net 45.45.45.0  0.0.0.255 area 0
R4(config-router)#net 5.5.5.5 0.0.0.0 area 0
R4(config-router)#ex

 ROUTER 5
R5(config)#router ospf 10
R5(config-router)#net 35.35.35.0 0.0.0.255 area 0
R5(config-router)#net 45.45.45.0 0.0.0.255 area 0
R5(config-router)#net 56.56.56.0 0.0.0.255 area 0
R5(config-router)#net 6.6.6.6 0.0.0.0 area 0
R5(config-router)#ex

 ROUTER 6
R6(config)#router ospf 10
R6(config-router)#net 56.56.56.0 0.0.0.255 area 0
R6(config-router)#net 67.67.67.0 0.0.0.255 area 0
R6(config-router)#net 7.7.7.7 0.0.0.0 area 2
R6(config-router)#ex


ROUTER 7
R7(config)#router ospf 10
R7(config-router)#net 67.67.67.0 0.0.0.255 area 0
R7(config-router)#net 7.7.7.7 0.0.0.0 area 2
R7(config-router)#ex



4.  jika ingin mengecek routing ospf berikut perintahnya!


R1#show ip route


5.  Setelah selesai kita melakukan semuanya kita melakukan ping ke router 1 ke router 3 dan lakukan sebaliknya pada setiap router.


sekian dari saya,sampai bertemu di postingan selanjutnya huussss byebye
