There are three basic elements of OSPF configuration:
==IP address==
 
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=192.168.122.100/24 interface=ether3
# /ip address add address=192.168.122.101/24 interface=ether3
# /ip address add address=192.168.122.102/24 interface=ether3
/ip dhcp-client remove number=0
/ip dhcp-client add interface=ether3 disabled=no        # kalau ether3 DHCP client
 
/ip firewall nat add chain=srcnat out-interface=ether3 action=masquerade
/ip firewall nat print
 
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=172.16.1.1/16 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=192.168.1.1/24 interface=ether3
 
==OSPF==
 
 
Ada tiga (3) elemen dasar konfigurasi OSPF:


* Enable OSPF instance
* Enable OSPF instance
* OSPF area configuration
* OSPF area configuration
* OSPF network configuration  
* OSPF network configuration  
instance name=default sudah ada, tidak perlu di tambahkan, tapi kalau perlu menambahkan caranya adalah sebagai berikut
Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.

       metric-bgp=auto metric-other-ospf=auto in-filter=ospf-in out-filter=ospf-out
out-filter=ospf-out
 
 
Create bridge interface named, for example, “loopback”:
 
[admin@MikroTikR1] /interface bridge> add name=loopback
 
Add IP address:
 
[admin@MikroTikR1] > ip address add address=10.255.255.1/32 interface=loopback
 
Configure router-id as loopback:
 
[admin@MikroTikR1] /routing ospf instance> set 0 router-id=10.255.255.1
 
 
This can be done on other routers (R2, R3) as well.
Note: Remember that backbone area-id is always (zero) 0.0.0.0.
 
On R1
 
[admin@MikroTikR1] /routing ospf network> add network=210.13.1.0/28 area=backbone
[admin@MikroTikR1] /routing ospf network> add network=10.10.1.0/30 area=backbone
[admin@MikroTikR1] /routing ospf network> add network=10.10.1.4/30 area=backbone
 
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

You can verify your OSPF operation as follows:
Cek


Look at the OSPF interface menu to verify that dynamic entry was created:
R1:


  [admin@MikroTikR1] /routing ospf interface> print
  /routing ospf interface print
 
  /routing ospf neighbor print
Check your OSPF neighbors, what DR and BDR is elected and adjacencies established:
  /ip route print
 
  [admin@MikroTikR1] /routing ospf neighbor> print
 
Check router’s routing table (make sure OSPF routes are present):
 
  [admin@MikroTik_CE1] > ip route print


Lakukan yang sama untuk R2, R3

OSPF

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 Catatan: Ingat bahwa backbone area-id adalah 0.0.0.0.


R1: 

# /routing ospf instance add name=default
/routing ospf instance set name=default router-id=10.10.1.1 numbers=0 
/routing ospf instance enable numbers=0
/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 instance add name=default
/routing ospf instance set name=default router-id=10.10.1.6 numbers=0
/routing ospf instance enable numbers=0
/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 instance add name=default
/routing ospf instance set name=default router-id=10.10.1.2 numbers=0
/routing ospf instance enable numbers=0
/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

Cek 

/routing ospf instance print 

Flags: X - disabled
