3 paź 2024 · Link state routing is a popular algorithm used in unicast routing to determine the shortest path in a network. Understanding how link state protocols work is key to mastering routing algorithms.
The three keys to understand the Link State Routing algorithm: Knowledge about the neighborhood: Instead of sending its routing table, a router sends the information about its neighborhood only. A router broadcast its identities and cost of the directly attached links to other routers.

CSE 123 – Lecture 12: Link-state Routing 24 Getting consistent routing information to all nodes E.g., all nodes having the same link-state database
18 mar 2024 · In this tutorial, we’ll learn about dynamic routing, focusing on distance vector- and link state-based strategies. First, we’ll briefly review the routing process, from basic concepts to categories. So, we’ll understand dynamic routing by defining its classes of distance vector and link state.
