OSPF on Packet Tracer

We are going to apply OSPF(open shortest path first) protocol on packet tracer. Let us take the following simple topology.



Now, let us apply the ospf on it. But before that, as usual :) , let us assign IP addresses and change the state of interfaces.

 

Similarly for the other router.



 
Assigning the IP addresses to PCs as follows.

 
 

Now, as we can see, interfaces are up but the communication is not enabled because we have not applied the protocol yet.

 
Lets do it.

 
On router 1.

 
After applying protocol successfully , the traffic is flowing . Couple of things worth discussing
i. you will have to provide area id and process id on ospf protocol.
ii. you will have to provide wildcard mask on ospf.
