Which statements accurately describe link state routing protocols?

Link state routing protocols are designed to route packets inside an Autonomous System (AS). They achieve this by having each router in the network maintain a complete map of the network topology, which is built through the exchange of link state advertisements (LSAs) among routers. This detailed knowledge of the network allows link state protocols, such as OSPF (Open Shortest Path First), to make more informed routing decisions, optimizing the path taken for packet delivery within the AS.

The scalability of link state protocols, compared to distance vector protocols like RIP (Routing Information Protocol), stems from their ability to quickly converge and efficiently manage larger networks due to the way they handle routing tables and utilize algorithms like Dijkstra's algorithm. This makes them suitable for environments with significant routing complexity.

Additionally, while link state protocols have capabilities that may involve routing between different ASes, such details pertain more to inter-domain routing protocols like BGP (Border Gateway Protocol) rather than the intrinsic behavior of link state protocols themselves. Hence, they primarily focus on routing within an AS.
