What is a Link State Routing Protocol?
Imagine a bustling city where every driver carries a complete, up-to-date map of every road, bridge, and intersection, rather than relying on directions from a single neighbor at each turn. This is the fundamental philosophy behind a link state routing protocol. In computer networking, this specific type of routing algorithm allows routers to share detailed information about their local connections with every other router in the network.
Not the most exciting part, but easily the most useful.
