I am little or more confused about the working ot OSPF.No matter how many times i tried to understand it but again i am left with lot of confusion and questions.
We say tht OSPF is different then RIP or IGRP or EIGRP as they are called distance vector protocols and OSPF is a link state protocol.
By the term distance vector means the routers are going to rely on the info recieved from the neighbors and forward it.
Well now we say tht OSPF is link state.
Here by link state me assume the interfaces on router which are up and OSPF is enabled on them.
So we take the example of distance vector with the below toplogy.
assume R1 has a network 192.168.1.0 advertise to R2 then R2 will advertise it R3 this is normal to DV protocols take the same toplogy with OSPF is going to be the same process if not whats the difference.
