Open shortest path rst
OSPF routing is a link-state routing protocol that allows sending of link-state advertisements (LSAs) to all other routers within the same
autonomous system (AS) area. Information about attached interfaces, metrics used, and other variables are included in OSPF LSAs. OSPF
routers accumulate link-state information, and use the shortest path rst (SPF) algorithm to calculate the shortest path to each node.
OSPF routers initially exchange hello messages to set up adjacencies with neighbor routers. The hello process establishes adjacencies
between routers of the AS — it is not required that every router within the AS areas establish adjacencies. If two routers on the same
subnet agree to become neighbors through this process, they begin to exchange network topology information in the form of LSAs.
In OSPF, neighbors on broadcast and non-broadcast multiple access (NBMA) network links are identied by their interface addresses, while
neighbors on other types of links are identied by router-identiers (RID).
