Hi Swee,

If you wanna see routes showing up, a minimum of two routers are required.

Connect two routers back to back and add some loopback interfaces to both the routers to simulate different networks and copy paste the below 3 lines on both of them


config t

router ospf 1

network area 0


Would recommend you to get a CCNA book and start looking into it for simpler explanations if you are new to ospf.

Hi Swee

OSPF is not having any limitation of router but atleast you need 2 router. This protocol is ment for small & Large or very large network.

And also having all those feature that req for an large network.

Please refer the below link to understand ospf and also please find the attach file to configure OSPF.
