Konfigurasi

Router1:

enable
configure terminal
  interface ethernet1/1
    ip address 10.10.1.1 255.255.255.252
    no shutdown
    exit
  interface ethernet1/2
    ip address 10.10.1.5 255.255.255.252

    exit
  !
  ! NAT GNS3 gw 192.168.122.1

    ip address 192.168.122.101 255.255.255.0 secondary
    ip address 192.168.122.102 255.255.255.0 secondary
    no shutdown
    ip route 0.0.0.0 0.0.0.0 192.168.122.1
  end

Router2:

enable
configure terminal
  interface ethernet1/1
    ip address 10.10.1.6 255.255.255.252
    no shutdown
    exit
  interface ethernet1/2
    ip address 10.10.1.9 255.255.255.252
    no shutdown
    exit
  interface ethernet1/3
    ip address 172.16.1.1 255.255.0.0
    no shutdown
    end

Router3:

enable
configure terminal
  interface ethernet1/1
    ip address 10.10.1.2 255.255.255.252
    no shutdown
    exit
  interface ethernet1/2
    ip address 10.10.1.10 255.255.255.252
    no shutdown
    exit
  interface ethernet1/3
    ip address 192.168.1.1 255.255.255.0
    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

enable
configure terminal
  !
  ! area 0 = backbone
  router ospf 1
  network 10.10.1.0 0.0.0.3 area 0.0.0.0
  network 10.10.1.4 0.0.0.3 area 0.0.0.0
  end

R2

enable
configure terminal
  !
  ! area 0 = backbone
  router ospf 2
  network 10.10.1.4 0.0.0.3 area 0.0.0.0
  network 10.10.1.8 0.0.0.3 area 0.0.0.0
  network 172.16.0.0 0.0.255.255 area 0.0.0.0
  end

R3

enable
configure terminal
  !
  ! area 0 = backbone
  router ospf 3
  network 10.10.1.0 0.0.0.3 area 0.0.0.0
  network 10.10.1.8 0.0.0.3 area 0.0.0.0
  network 192.168.1.0 0.0.0.255 area 0.0.0.0
  end

Verify

Cek di R1, R2, R3

show ip ospf neighbor
show ip ospf database
