OSPF LSA (Open Shortest Path First Link-State Advertisement) is a packet used by OSPF routers to exchange information about the network topology.
OSPF LSA Definition: OSPF LSA (Open Shortest Path First Link-State Advertisement) is a packet used by OSPF routers to exchange information about the network topology.
OSPF LSA (Link State Advertisement) is a data structure used by the OSPF (Open Shortest Path First) routing protocol to exchange network topology information between OSPF routers. LSAs contain information about local and neighboring routers, network links, and routing metrics. They are flooded throughout the OSPF network to maintain a consistent view of network topology and compute optimal routing paths. Different types of LSAs exist, each serving a specific purpose in the OSPF routing process.
