OSPF continues to update routers about available routes after they have
converged. These route updates are sent in the form of link-state advertise-ment (LSA) packets. Routers exchange LSA packets to maintain their link-state tables . After they have built their neighbor and link-state tables, routers
know the following:
✦ Their neighbors
✦ The network topology in their immediate vicinity
✦ The network topology in the vicinity of their neighbors
Next, each router evaluates the quality of each route registered in the link-state table.
