Konfigurasi virtual link

 Assalamualaikum wr.wb

Sekarang saya ingin mengkonfigurasi virtual link.

Langsung aja kita ke konfigurasi nya.

Topologi sebagai berikut.

R1

conf t

hostname R1-ripal

int f0/0

ip add 172.16.12.1 255.255.255.0

int f0/1

ip add 192.168.1.1 255.255.255.0

int lo0

ip add 1.1.1.1 255.255.255.255

router ospf 1

net 192.168.1.0 0.0.0.255 area 0

net 172.16.12.0 0.0.0.255 area 0

net 1.1.1.1 0.0.0.0 area 0

R2

conf t

hostname R2-ripal

int f0/0

ip add 172.16.12.2 255.255.255.0

int f0/1

ip add 172.16.23.2 255.255.255.0

int f1/0

ip add 192.168.2.1 255.255.255.0

int lo0

ip add 2.2.2.2 255.255.255.255

router ospf 1

net 192.168.2.0 0.0.0.255 area 0

net 172.16.12.0 0.0.0.255 area 0

net 172.16.23.0 0.0.0.255 area 1

net 2.2.2.2 0.0.0.0 area 1

area 1 virtual-link 3.3.3.3

R3

conf t

hostname R3-ripal

int f0/0

ip add 172.16.34.3 255.255.255.0

int f0/1

ip add 172.16.23.3 255.255.255.0

int f1/0

ip add 192.168.3.1 255.255.255.0

int lo0

ip add 3.3.3.3 255.255.255.255

router ospf 1

net 192.168.3.0 0.0.0.255 area 1

net 172.16.34.0 0.0.0.255 area 2

net 172.16.23.0 0.0.0.255 area 1

net 3.3.3.3 0.0.0.0 area 1

area 1 virtual-link 2.2.2.2

R4

conf t

hostname R4-ripal

int f0/0

ip add 172.16.34.4 255.255.255.0

int f0/1

ip add 192.168.4.1 255.255.255.0

int lo0

ip add 4.4.4.4 255.255.255.255

router ospf 1

net 192.168.4.0 0.0.0.255 area 2

net 172.16.34.0 0.0.0.255 area 2

net 4.4.4.4 0.0.0.0 area 2

lalu setelah itu kalian memberi ke setiap PC sesuai topologi di atas seperti:

PC 1:192.168.1.2/24 

PC 2:192.168.2.2/24

PC 3:192.168.3.2/24

PC 4:192.168.4.2/24

jika sudah kalian coba ping kalo semua PC bisa ping berarti konfigurasinya berhasil.
