What is OSPF? OSPF (Open Shortest Path First) is a routing protocol that automatically finds the best route to a network. It is technically a link-state protocol, which means each router in a network has a map of the network. The reason you use OSPF is that in a network with multiple routers, you would normally have to configure a route to each network on every router. This doesn’t sound too bad if you only have 2 or 3 routers, but what if you have 10, and the network changes frequently? This would take forever to maintain manually. OSPF does it automatically for you. ...

What is a Broadcast Storm A broadcast is like speaking to a crowd of people using a microphone so everyone can hear you. In a computer network, it works similarly, allowing a frame to be sent to every device on that VLAN. ...
