Understanding Dynamic Routing: Distance Vector vs. Link State

TLDRLearn about dynamic routing and the differences between distance vector and link state protocols. Distance vector protocols use 'routing by rumor' and share route information with neighbors, while link state protocols create a connectivity map of the network. Each routing protocol uses a different metric to determine the best route to a destination.

Key insights

💡Distance vector protocols operate by 'routing by rumor', sharing information with neighbors

🌐Link state protocols create a complete connectivity map of the network

📉Distance vector protocols use hop count as the metric for determining best routes

🔍Link state protocols use a more comprehensive set of metrics to calculate best routes

🔄Equal Cost Multipath Load-Balancing allows for load distribution across multiple routes with equal metrics

Q&A

What is the difference between distance vector and link state routing protocols?

Distance vector protocols operate by 'routing by rumor' and share route information with neighbors, while link state protocols create a connectivity map of the network.

How do routing protocols determine the best route to a destination?

Each routing protocol uses a specific metric, such as hop count, bandwidth, or delay, to calculate the best route to a destination.

What is Equal Cost Multipath Load-Balancing?

Equal Cost Multipath Load-Balancing allows for load distribution across multiple routes with equal metrics, optimizing network performance and redundancy.

Which routing protocols use hop count as the metric?

Distance vector protocols, such as RIP, use hop count as the metric for determining the best route.

How do link state protocols calculate the best routes?

Link state protocols use a more comprehensive set of metrics, including bandwidth, delay, reliability, and cost, to calculate the best routes.
