Routing

Routing is a network layer process that determines the optimal path for packet delivery between networks. It includes static routing, which is manually configured for security and resource efficiency but lacks flexibility, and dynamic routing, which automatically adjusts routes based on current conditions but consumes more bandwidth and is less secure. Default routing forwards all packets to a single router regardless of their destination.
Routing
- 3. Routing is a process which is performed by layer 3 (or network layer) devices in order to deliver the packet by choosing an optional path from one network to another.
- 4. Default Routing Dynamic Routing Static Routing
- 5. Static routing is a process in which we have to manually add routes in routing table.
- 6. • It is easy to implement. • It is most secure way of routing, since no information is shared with other routers. • It puts no overhead on resources such as CPU or memory. • It is suitable only for small network. • If a link fails it cannot reroute the traffic.
- 7. Dynamic routing is the process in which routes are automatically adjusted on the basis of a current state of the route in the routing table.
- 8. It is easy to configure. • More effective at selecting the best route to a destination remote network and also for discovering remote network. • Consumes more bandwidth for communicating with other neighbors. • Less secure than static routing.
- 9. The router is configured to send all packets towards a single router. It doesn’t matter to which network the packet belongs, it is forwarded out to router which is configured for default routing.
