OSPF Operations
- Routers send LSA’s which include the description of the router’s links, and the state of each of link adjacent to the router.
- Routers that receive the LSA update their link state databases and forward the LSA’s on to their respective neighbors. This allows all routers taking part in the OSPF process to have the same view of the network.
- After learning all the LSA’s, each router runs the Dijkstra SPF algorithm to learn the shortest path to all known destinations. Each router uses this information to create its SPF Tree. The information in the SPT Tree is then populated to the routing table.
