Differentiate between static and dynamic routing.

Last updated on 

Static and dynamic routing are two approaches to managing the flow of network traffic in a computer network. Here's a differentiation between static and dynamic routing:

  1. Definition:
    • Static Routing:
      • In static routing, network administrators manually configure the routing tables on routers. Routes are explicitly defined, and the routers do not exchange information with each other to dynamically update routing tables.
      • It is a manual and fixed method of routing, where paths are predetermined and don't change unless explicitly modified by an administrator.
    • Dynamic Routing:
      • Dynamic routing relies on routing protocols to allow routers to exchange information about the network topology dynamically. Routers communicate with each other to automatically update routing tables based on changes in the network.
      • This approach adapts to changes in the network, making it more scalable and flexible compared to static routing.
  2. Configuration:
    • Static Routing:
      • Configuration is done manually by the network administrator, specifying the routes and their associated metrics.
      • It is suitable for small networks with a relatively stable topology.
    • Dynamic Routing:
      • Configuration is automated using routing protocols. Routers share information with each other, and routes are dynamically updated based on changes in the network.
      • Well-suited for larger networks with dynamic and evolving topologies.
  3. Scalability:
    • Static Routing:
      • Not very scalable, as each change in the network requires manual configuration on every affected router.
    • Dynamic Routing:
      • More scalable, as routers can adapt to changes automatically without manual intervention.
  4. Maintenance:
    • Static Routing:
      • Requires manual maintenance and updates whenever there are changes in the network topology.
    • Dynamic Routing:
      • Requires less manual intervention for maintenance, as routers exchange information and update routes dynamically.
  5. Adaptability:
    • Static Routing:
      • Less adaptable to changes in the network, as adjustments must be made manually.
    • Dynamic Routing:
      • More adaptable to changes, making it suitable for large and dynamic networks.
  6. Examples:
    • Static Routing:
      • Configuring a default route pointing to a specific gateway.
    • Dynamic Routing:
      • Routing Information Protocol (RIP), Open Shortest Path First (OSPF), Border Gateway Protocol (BGP) are examples of dynamic routing protocols.

Static routing involves manually configuring routes, which is suitable for smaller, stable networks. Dynamic routing, on the other hand, relies on automated protocols to dynamically adapt to changes in larger and more dynamic networks.
