Each router then updates its table based on the information received, relying on the "distance" to each destination.
In contrast, link-state algorithms, such as OSPF (Open Shortest Path First), operate by maintaining a complete topology of the network. Each router sends link-state advertisements to all other routers. This allows each router to independently calculate the shortest path to every other router using Dijkstra’s algorithm, resulting in more efficient routing based on current conditions.
The implementation of these algorithms involves precise configuration and ongoing maintenance of routing tables. Dynamic routing protocols facilitate adaptive routing, enabling routers to respond to network changes and failures effectively, ensuring optimal data transmission and network performance.
