Dynamic Routing
Dynamic routing makes automatic adjustments of the routes according to the current state of the route in the routing table. Dynamic routing uses protocols to discover network destinations and the routes to reach them. RIP and OSPF are the best examples of dynamic routing protocols. Automatic adjustments will be made to reach the network destination if one route goes down.
A dynamic protocol has the following features:
- The routers should have the same dynamic protocol running in order to exchange routes.
- When a router finds a change in the topology then the router advertises it to all other routers.
Advantages
- Easy to configure.
- More effective at selecting the best route to a destination remote network and also for discovering remote networks.
Disadvantage
- Consumes more bandwidth for communicating with other neighbors.
- Less secure than static routing.
Types of Routing
Routing is a process that is performed by layer 3 (or network layer) devices in order to deliver the packet by choosing an optimal path from one network to another.
