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:

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

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

There are three basic elements of OSPF configuration:

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


R1: 

[admin@MikroTikR1] /routing ospf instance> add name=default

R2: 

[admin@MikroTikR2] /routing ospf instance> add name=default

R3: 

[admin@MikroTikR3] /routing ospf instance> add name=default


Cek 

[admin@MikroTikR1] /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


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

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
