R1 ethernet0 - R3 ethernet0
R1 ethernet1 - R2 ethernet0
R2 ethernet1 - R3 ethernet1
R2 ethernet2 - 172.16.1.1/16
R3 ethernet2 - 192.168.1.1/24


Konfigurasi

Router1:

/ip address add address=10.10.1.1/30 interface=ether1
/ip address add address=10.10.1.5/30 interface=ether2


/ip dhcp-client add interface=ether3 disabled=no        # kalau ether3 DHCP client
/ip firewall nat add chain=srcnat out-interface=ether3 action=masquareade
/ip firewall nat print


Router2 (Quagga):

vtysh
enable
configure terminal
  interface eth0
    ip address 10.10.1.6/30
    link-detect
    exit
  interface eth1
    ip address 10.10.1.9/30
    link-detect
    exit
  interface eth2
    ip address 172.16.1.1/16
    link-detect
    exit

Router3 (Quagga):

vtysh
enable
configure terminal
  interface eth0
    ip address 10.10.1.2/30
    link-detect
    exit
  interface eth1
    ip address 10.10.1.10/30
    link-detect
    exit
  interface eth2
    ip address 192.168.1.1/24
    link-detect
    exit


Ada tiga (3) elemen dasar konfigurasi OSPF:

  • Enable OSPF instance
  • OSPF area configuration
  • OSPF network configuration

instance name=default sudah ada, tidak perlu di tambahkan, tapi kalau perlu menambahkan caranya adalah sebagai berikut

R1:

/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

/routing ospf instance print 
Flags: X - disabled 
 0   name="default" router-id=0.0.0.0 distribute-default=never 
     redistribute-connected=as-type-1 redistribute-static=as-type-1 
     redistribute-rip=no redistribute-bgp=no redistribute-other-ospf=no 
     metric-default=1 metric-connected=20 metric-static=20 metric-rip=20 
     metric-bgp=auto metric-other-ospf=auto in-filter=ospf-in 
out-filter=ospf-out


Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.

R1

/routing ospf network add network=10.10.1.0/30 area=backbone
/routing ospf network add network=10.10.1.4/30 area=backbone 

R2

/routing ospf network add network=10.10.1.4/30 area=backbone 
/routing ospf network add network=10.10.1.8/30 area=backbone 
/routing ospf network add network=172.16.0.0/16 area=backbone 

R3

/routing ospf network add network=10.10.1.0/30 area=backbone 
/routing ospf network add network=10.10.1.8/30 area=backbone 
/routing ospf network add network=192.168.1.0/24 area=backbone

Atau kalau di aggregate

R1:

/routing ospf network add network=10.10.1.0/24 area=backbone


R2:

/routing ospf network add network=172.16.0.0/16 area=backbone
/routing ospf network add network=10.10.1.0/24 area=backbone

R3:

/routing ospf network add network=192.168.1.0/24 area=backbone
/routing ospf network add network=10.10.1.0/24 area=backbone

Verify

Cek

R1:

/routing ospf interface print
/routing ospf neighbor print
/ip route print

Lakukan yang sama untuk R2, R3
