Overview
Dynamic routing allows routers to share information about network reachability and status in real-time. This enables the network to automatically reroute traffic if a link fails or a better path becomes available.
Key Characteristics
- Adaptability: Automatically adjusts to topology changes.
- Scalability: Suitable for large and complex networks.
- Complexity: Requires more router resources (CPU, RAM) and configuration knowledge than static routing.
How it Works
Routers run a routing protocol (like OSPF or BGP) to exchange routing updates. Each router uses this information to build and maintain its own routing table.
