Instead of typing in each network, you can aggregate networks using appropriate subnet mask. For example, to aggregate 10.10.1.0/30, 10.10.1.4/30, 10.10.1.8/30 networks, you can set up following ospf network:

Router1:

/ip address add address=10.10.1.1/30 interface=ether1
/ip address add address=10.10.1.5/30 interface=ether2
/ip address add address=210.13.1.0/28 interface=ether3  # kalau ether3 statik
/ip dhcp-client add interface=ether3 disabled=no        # kalau ether3 DHCP client


Router2:

/ip address add address=10.10.1.6/30 interface=ether1
/ip address add address=10.10.1.9/30 interface=ether2
/ip address add address=172.16.1.0/16 interface=ether3

Router3:

/ip address add address=10.10.1.2 /30 interface=ether1
/ip address add address=10.10.1.10/30 interface=ether2
/ip address add address=192.168.1.0/24 interface=ether3


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> add name=default

R2:

/routing ospf instance> add name=default

R3:

/routing ospf instance> add name=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

Buat bridge "loopback" untuk R1, R2, R3

/interface bridge add name=loopback
/ip address add address=10.255.255.1/32 interface=loopback 
/routing ospf instance set 0 router-id=10.255.255.1

Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.

R1

/routing ospf network add network=210.13.1.0/28 area=backbone
/routing ospf network add network=0.0.0.0/0 area=backbone   # default ke Internet
/routing ospf network add network=10.10.1.0/30 area=backbone
/routing ospf network add network=10.10.1.4/30 area=backbone

R3


Instead of typing in each network, you can aggregate networks using appropriate subnet mask. For example, to aggregate 10.10.1.0/30, 10.10.1.4/30, 10.10.1.8/30 networks, you can set up following ospf network:

[admin@MikroTikR1] /routing ospf network> add network=10.10.1.0/24 area=backbone


R2:

[admin@MikroTikR2] /routing ospf network> add network=172.16.1.0/16 area=backbone
[admin@MikroTikR2] /routing ospf network> add network=10.10.1.0/24 area=backbone

R3:

[admin@MikroTikR3] /routing ospf network> add network=192.168.1.0/24 area=backbone
[admin@MikroTikR3] /routing ospf network> add network=10.10.1.0/24 area=backbone

Verify

You can verify your OSPF operation as follows:

Look at the OSPF interface menu to verify that dynamic entry was created:

[admin@MikroTikR1] /routing ospf interface> print

Check your OSPF neighbors, what DR and BDR is elected and adjacencies established:

[admin@MikroTikR1] /routing ospf neighbor> print

Check router’s routing table (make sure OSPF routes are present):

[admin@MikroTik_CE1] > ip route print
