OSPF Visibility of the Network.
Unlike RIP and EIGRP, OSPF is a Link State protocol, what does that mean ? does it mean a router configured with OSPF knows the topology in every router that is configured with OSPF ?at least the routers that are in t same area ?
Reading about SDN , this technology has a capability to have visibility of the whole network topology. is it the same as OSPF routers in the same area ?
