• It allows network administrators to group hosts together based on their functions

• Each VLAN has a unique ID and can span multiple switches

• OSI model has 7 layers: Physical, Data Link, Network, Transport, Session, Presentation, and Application

OSPF is used for dynamic routing in large networks, providing scalability, fast convergence, and load balancing.

• OSPF is a link-state routing protocol that calculates the shortest path between routers using Dijkstra's algorithm.

• It supports variable-length subnet masks (VLSM) and classless inter-domain routing (CIDR).

• OSPF uses a hierarchical network design with areas to reduce the size of the routing table and improve ne...read more
