instance name=default sudah ada, tidak perlu di tambahkan, tapi kalau perlu menambahkan caranya adalah sebagai berikut
R1:
/routing ospf instance add name=default
/routing ospf instance enable default
R2:
/routing ospf instance add name=default
/routing ospf instance enable default
R3:
/routing ospf instance add name=default
/routing ospf instance enable default
Cek

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
    no shutdown
    exit
  !
  ! NAT GNS3 gw 192.168.122.1
  interface ethernet1/3
    ip address 192.168.122.100 255.255.255.0
    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 
show ip route
