OSPF: SPF Calculation

Once OSPF has collected all known LSAs and installed them into its LSDB, it begins the process of calculating the shortest path to each network using the SPF algorithm.

Using all the data collected from each of the LSAs, the SPF algorithm takes that data and computes each path to a network as a mathematical number and sums the cost to reach the network.  Routes with the lowest cost to reach a network win and are injected into the routing table.
