Open Shortest Path First(OSPF)
Question
Open Shortest Path First(OSPF)
Solution
Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It uses a link state routing algorithm and falls into the group of interior gateway protocols, operating within a single autonomous system (AS). Here's a step-by-step explanation of how it works:
-
Establishment of Adjacencies: Each OSPF router establishes an adjacency (relationship) with its neighbors. The routers exchange Hello packets to form these adjacencies.
-
Database Exchange: Once the adjacency is formed, the routers exchange link-state database (LSDB)
